Chap. 60.—The Nature of the Murex and the Purple.

And yet pearls may be looked upon as pretty nearly a possession of everlasting duration—they descend from a man to his heir, and they are alienated from one to another just like any landed estate. But the colours that are extracted from the murex [Or “conchylium.” We find that Pliny generally makes a difference between the colours of the “murex,” or “conchylium,” and those of the “purpura,” or “purple.” Cuvier says, that they were the names of different shell-fish which the ancients employed for dyeing in purple of various shades. It is not known exactly, at the present day, what species they employed; but it is a fact well ascertained, that the greater part of the univalve shell-fish, more especially the Buccini and Murices of Linnæus, distil a kind of red liquid. The dearness of it arose, Cuvier thinks, from the remarkably small quantity that each animal afforded. Since the coccus, or kermes, he says, came to be well known, and more especially since the New World has supplied us with cochineal, we are no longer necessitated to have recourse to the juices of the murex.] and the purple fade from hour to hour; and yet luxury, which has similarly acted as a mother to them, has set upon them prices almost equal to those of pearls.

(36.) Purples live mostly seven [Aristotle, Hist. Anim. B. v. c. 14, says, “about six.” The murex of Pliny is the κήρυξ of Aristotle.] years. Like the murex, they keep themselves in concealment for thirty days, about the time of the rising of the Dog-star; in the spring season they unite in large bodies, and by rubbing against each other, produce a viscous spittle, from which a kind of wax is formed. The murex does the same; but the purple [Aristotle says, that the purple consists of three parts, the upper being the τράχηλος, or neck; the middle the μήκων, or poppy; and the lower the πυθμήν, or trunk; and that the juice lies between the first and second of these parts, or the throat. This juice, which Pliny calls “flos,” “flower,” “ros,” “dew,” and “succus,” “juice,” is distilled, Cuvier says, not from the fauces of the animal, but from the mantle or membranous tissue which lines the shell.] has that exquisite juice which is so greatly sought after for the purpose of dyeing cloth, situate in the middle of the throat. This secretion consists of a tiny drop contained in a white vein, from which the precious liquid used for dyeing is distilled, being of the tint of a rose somewhat inclining to black. The rest of the body is entirely destitute of this juice. It is a great point to take the fish alive; for when it dies, it spits out this juice. From the larger ones it is extracted after taking off the shell; but the small fish are crushed alive, together with the shells, upon which they eject this secretion.

In Asia the best purple is that of Tyre, in Africa that of Meninx [See B. v. c. 7. See also B. vi. c..] and the parts of Gætulia that border on the Ocean, and in Europe that of Laconia. It is for this colour that the fasces and the axes [Which preceded the Roman consuls, who were clothed with the toga prætexta, the colour of which was Syrian purple.] of Rome make way in the crowd; it is this that asserts the majesty of childhood; [Hardouin seems to think that “majestate pueritiæ” means “children of high birth;” but it was the fact that all children of free birth wore the prætexta, edged with purple, till they attained puberty. It is much more probable that by these words Pliny means the “majesty of youth,” in its simplicity and guileless nature, that commands our veneration and respect.] it is this that distinguishes the senator [He means that the purple laticlave or broad hem of the senator’s toga distinguished him from the eques, who wore a toga with an angusticlave, or narrow hem.] from the man of equestrian rank; by persons arrayed in this colour are prayers [From Cicero, Epist. Ad. Attic. B. ii. Ep. 9, we learn that purple was worn by the priests when performing sacrifice. Ajasson, however, agrees with Dalechamps in thinking that this passage bears reference to the consuls, who wore purple when sacrificing to the gods.] addressed to propitiate the gods; on every garment [The prætexta, for instance, the laticlave, the chlamys, the paludamentum, and the trabea.] it sheds a lustre, and in the triumphal vestment [On the occasion of a triumph, the victor was arrayed in a “toga picta,” an embroidered garment, which, from the present passage, would appear to have been of purple and gold. Pliny tells us, B. xxxiii. c. 19, that Tarquinius, on his triumph over the Sabines, wore a robe of cloth of gold.] it is to be seen mingled with gold. Let us be prepared then to excuse this frantic passion for purple, even though at the same time we are compelled to enquire, why it is that such a high value has been set upon the produce of this shell-fish, seeing that while in the dye the smell of it is offensive, and the colour itself is harsh, of a greenish hue, and strongly resembling that of the sea when in a tempestuous state?

The tongue of the purple is a finger [Aristotle says the same, Hist. Anim. B. v. c. 14, and De Partib. Anim. B. ii. c. 17. Cuvier says, that the buccinus and murex have a long neck, in which there is a tongue armed with little teeth, but very sharp, by means of which the animal is enabled to pierce other shell-fish.] in length, and by means of this it finds subsistence, by piercing other shell-fish, [“Conchylia;” other fish of the same kind apparently; as Pliny uses the word “conchylium” synonymously with “murex.”] so hard is the point of it. They die in fresh water, and in places where rivers discharge themselves into the sea; otherwise, when taken, they will live as long as fifty days on their saliva. All shell-fish grow very fast, and purples more especially; they come to their full size at the end of a year.

Chap. 61.—The Different Kinds of Purples.

Were I at this point to pass on to other subjects, luxury, no doubt would think itself defrauded of its due, and so accuse me of negligence; I must therefore make my way into the very workshops even, so that, just as among articles of food the various kinds and qualities of corn are known, all those who place the enjoyment of life in these luxuries, may have a still better acquaintance with the objects for which they live. [“Præmia vitæ suæ.”]

There are two kinds of fish that produce the purple colour; the elements in both are the same, the combinations only are different; the smaller fish is that which is called the “buccinum,” from its resemblance to the conch by which the sound of the buccinus or trumpet is produced, and to this circumstance it owes its name: the opening in it is round, with an incision in the margin. [Cuvier says that the buccini, properly so called, have at the bottom of the orifice of the shell an incision, which is the characteristic of the genus. Our whelks are the best known specimen of the buccinum that we have. They received their name, he says, from the buccinum, or buccina, the conch-shell, (with which Triton is commonly painted), and that in its turn was so called from its resemblance to a buccina, trumpet or herdsman’s horn.] The other fish is known as the “purpura,” or purple, and has a grooved and projecting muzzle, which being tubulated on one side in the interior, forms a passage for the tongue; [It is not the tongue, Cuvier says, that occupies this passage, but a prolongation of the skin or coat that envelopes the animal, and its office is to conduct to the branchiæ the water necessary for the purposes of respiration.] besides which, the shell is studded with points up to the very apex, which are mostly seven in number, and disposed [This description, Cuvier says, is applicable to the Murex brandaris, the Murex tribulus of Linnæus, and other species that denote their growth by the increase of the spirals furnished with spines.] in a circle; these are not found on the buccinum, though both of them have as many spirals as they are years old. The buccinum attaches itself only to crags, and is gathered about rocky places.

(37.) Purples also have another name, that of “pelagiæ” [Or “deep sea” purples. Dalechamps remarks, that Pliny here unwittingly gives to the purples in general, a name which only belonged to one species; there being some that only frequent the shore, and are not found out at sea.] there are numerous kinds of them, which differ only in their element and place of abode. There is the mud [“Lutensis.”] purple, which is nurtured upon putrid mud; and the sea-weed [“Algensis.”] purple, which feeds on sea-weed; both of which are held in the very lowest esteem. A better kind is the reef-purple, [“Tæniensis.”] which is collected on the reefs or out at sea; still, however, the colour extracted from this is too light and thin. Then, again, there is the variety known as the pebble-purple, [“Calculensis.”] so called from the pebbles of the sea, and wonderfully well adapted for dyeing; and, better than any of them, that known by the name of “dialutensis,” [From the Greek διαλυτὸς, “free,” or “roving;” in consequence of its peculiar mode of life.] because of the various natures of the soil on which it feeds. Purples are taken with a kind of osier kipe [Nassis. See Note in p. 421.] of small size, and with large meshes; these are cast into the sea, and in them cockles are put as a bait, that close the shell in an instant, and snap at an object, just as we see mussels do. Though half dead, these animals, as soon as ever they are returned to the sea, come to life again, and open their shells with avidity; upon which the purples seek them, and commence the attack, by protruding their tongues. The cockles, on the other hand, the moment they feel themselves pricked, shut their shells, and hold fast the object that has wounded them: in this way, victims to their greediness, they are drawn up to the surface hanging by the tongue.

Chap. 62. (38.)—How Wools Are Dyed with the Juices of the Purple.

The most favourable season for taking these fish is after the rising of the Dog-star, or else before spring; for when they have once discharged [“Quum cerificavere.” Cuvier remarks that Aristotle, Hist. Anim. B. v. c. 14, says, that these shell-fish make “waxen combs,” meaning thereby collections of cells, similar to those formed by the bee; and it is to this notion that Pliny refers in the use of the word “cerificavere.” It is the fact, Cuvier says, that the univalve sea shell-fish, and more particularly the buccini and the murices, envelope their eggs with glutinous vesicles of varied forms, according to the respective species; which, when massed together, may be not inappropriately termed “combs.”] their waxy secretion, their juices have no consistency: this, however, is a fact unknown in the dyers’ workshops, although it is a point of primary importance. After it is taken, the vein is extracted, which we have [In c. 60. As Cuvier remarks, with considerable justice, this description by Pliny of the process of dyeing in purple, is very difficult to explain, seeing that the art is now entirely lost. Reaumur, he says, made some attempts at dyeing with a small buccinum found off the French coasts, the Buccinum lapillus of Linnæus; but without any result.] previously spoken of, to which it is requisite to add salt, a sextarius [About twenty ounces.] about to every hundred pounds of juice. It is sufficient to leave them to steep for a period of three days, and no more, for the fresher they are, the greater virtue there is in the liquor. It is then set to boil in vessels of tin, [Because iron or brazen vessels might impart a tinge to the colour. The same would probably be the case if the word “plumbo” were to be considered as signifying “lead.” As, however, Pliny uses this word in the signification of “tin,” it is most probable that that is his meaning. Littré, however, translates the word “plombe,” “lead.”] and every hundred amphoræ [Hardouin says, that the weight of the contents of the amphora would be about eighty pounds: it would therefore take eight thousand pounds of material to make five hundred pounds of dye. The passage, however, which runs as follows, “Fervere in plumbo, singulasque amphoras centenas ad quingentenas medicaminis libras æquari,” may be rendered, “It is then set to boil in vessels of tin, and every hundred amphoræ of water ought to be proportioned to five hundred pounds of the material;” indeed, this is probably the correct translation, though Littré, who is generally very exact, adopts that given in the text.] ought to be boiled down to five hundred pounds of dye, by the application of a moderate heat; for which purpose the vessel is placed at the end of a long funnel, which communicates with the furnace; while thus boiling, the liquor is skimmed from time to time, and with it the flesh, which necessarily adheres to the veins. About the tenth day, generally, the whole contents of the cauldron are in a liquified state, upon which a fleece, from which the grease has been cleansed, is plunged into it by way of making trial; but until such time as the colour is found to satisfy the wishes of those preparing it, the liquor is still kept on the boil. The tint that inclines to red is looked upon as inferior to that which is of a blackish hue. The wool is left to lie in soak for five hours, and then, after carding it, it is thrown in again, until it has fully imbibed the colour. The juice of the buccinum is considered very inferior if employed by itself, as it is found to discharge its colour; but when used in conjunction with that of the pelagiæ, it blends [“Alligatur:” which word may also mean, that mixed with the buccinum, it will hold fast, and not speedily fade or wash out.] with it very well, gives a bright lustre to its colour, which is otherwise too dark, and imparts the shining crimson hue of the kermes-berry, a tint that is particularly valued. By the admixture of their respective virtues these colours are thus heightened or rendered sombre by the aid of one another. The proper proportions for mixing are, for fifty pounds of wool, two hundred pounds of juice of the buccinum and one hundred and eleven of juice of the pelagiæ. From this combination is produced the admirable tint known as amethyst colour. [So called from the gem of that name; see B. xxxvii. c. 40.] To produce the Tyrian hue the wool is soaked in the juice of the pelagiæ while the mixture is in an uncooked and raw state; after which its tint is changed by being dipped in the juice of the buccinum. It is considered of the best quality when it has exactly the colour of clotted blood, and is of a blackish hue to the sight, but of a shining appearance when held up to the light; hence it is that we find Homer speaking of “purple blood.” [Aἵματι πορφυρέῳ. Il. Ρ. l. 360, for instance.]

Chap. 63. (39.)—When Purple Was First Used at Rome: When the Laticlave Vestment and the Prætexta Were First Worn.

I find that, from the very first, purple has been in use at Rome, but that Romulus employed it for the trabea. [The “trabea” was similar in cut to the toga, but was ornamented with purple horizontal stripes. Servius mentions three kinds of trabea; one wholly of purple, which was sacred to the gods, another of purple and white, and another of purple and saffron, which belonged to the augurs. The purple and white trabea was the royal robe, worn by the early kings, and the introduction of which was assigned to Romulus. The trabea was worn by the consuls in public solemnities, such as opening the temple of Janus. The equites also wore it on particular occasions; and it is sometimes spoken of as the badge of the equestrian order.] As to the toga prætexta and the laticlave [The latus clavus, or laticlave, was originally worn on the tunic, and was a distinctive badge of the senatorian order. It consisted of a single broad band of purple colour, extending perpendicularly from the neck down the centre of the tunic. The right of wearing the laticlave was given to children of the equestrian order, at least, as we learn from Ovid, in the reign of Augustus.] vestment, it is a fact well ascertained, that Tullus Hostilius was the first king who made use of them, and that after the conquest of the Etruscans. Cornelius Nepos, who died in the reign of the late Emperor Augustus, has left the following remarks: “In the days of my youth,” says he, “the violet purple was in favour, a pound of which used to sell at one hundred denarii; and not long after, the Tarentine [Hardouin says, that in his time there were still to be seen the remains of the ancient dyeing houses at Tarentum, the modern Otranto, and that vast heaps of the shells of the murex had been discovered there.] red was all the fashion. This last was succeeded by the Tyrian dibapha, [Cloths doubly dyed, or twice dipped: from the Greek δὶς, twice, and βάπτω, to dip.] which could not be bought for even one thousand denarii per pound. P. Lentulus Spinther, the curule ædile, was the first who used the dibapha for the prætexta, and he was greatly censured for it; whereas now-a-days,” says he, “who is there that does not have purple hangings [“Triclinaria.” This word probably signified not only the hangings of the table couches, but the coverings, and the coverlets which were spread over the guests while at the meal.] to his banqueting-couches, even?”

This Spinther was ædile in the consulship of Cicero, and in the year from the Building of the City, 691. “Dibapha” was the name given to textures that had been doubly dyed, and these were looked upon as a mighty piece of costly extravagance; while now, at the present day, nearly all the purple cloths that are reckoned of any account are dyed in a similar manner.

Chap. 64.—Fabrics Called Conchyliated.

Fabrics that are called conchyliated are subjected to the same process in all other respects, but without any admixture of the juice of the buccinum; in addition to which, the liquid is mixed with water and human urine in equal parts, [“Pro indiviso.”] one-half [“Dimidia et medicamina adduntur.” This, no doubt, is the sense of the passage, as it is evident that only a thinner dye was required for tint, though at first sight it would appear as though one-half more were required for the same quantity of wool. The quantity therefore would be 155½ pounds of dye to fifty pounds of wool.] only of the proportion of dye being used for the same quantity of wool. From this mixture a full colour is not obtained, but that pale tint, which is so highly esteemed; and the clearer [“Tantoque dilutior, quanto magis vellera esuriunt.” This seems to be the meaning of the passage: some commentators would read “dilucidior” for “dilutior,” and it would appear to be preferable.] it is, the less of it the wool has imbibed.

(40.) The prices of these dyes vary in proportion to the quantity produced by the various shores; still, however, those who are in the habit of paying enormous prices for them, may as well be informed that on no occasion ought the juice of the pelagiæ to exceed fifty, [There can be little doubt that Salmasius is right in his conjecture that the reading here should be “quingentos,” “five hundred,” instead of “quinquagenos,” “fifty:” as it is evident from what Pliny has said in previous Chapters, that the juices of the pelagia were considerably more valuable than those of the buccinum.] and that of the buccinum one hundred sesterces for one hundred pounds. [He states this by way of warning to those who are in the habit of paying enormous prices for dyes, such as one hundred denarii for a pound, as mentioned in the last Chapter.]

Chap. 65.—The Amethyst, the Tyrian, the Hysginian, and the Crimson Tints.

But no sooner have we finished with one branch of this subject than we have to begin upon another, for we find that it is made quite a matter of sport to create expense; and not only this, but the sport must be doubled by making new mixtures and combinations, and falsifying over again what was a falsification of the works of Nature already; such, for instance, as staining tortoise-shell, [This is mentioned more fully in B. xvi. c. 84.] alloying gold with silver for the purpose of making electrum, [See B. xxxiii. c. 23. Electrum was an artificial metal, resembling amber in colour, and consisting of gold alloyed with one-fifth part of silver.] and then adding copper to the mixture to make Corinthian metal. [See B. xxxiv. c. 3. It was a mixture of gold, silver, and copper.]

(41.) It was not sufficient to have borrowed from a precious stone the name of “amethyst” for a dye, but when we have obtained this colour we must drench it over again with Tyrian tints, [Described at the end of c. 62.] so that we may have an upstart name [“Nomen improbum.”] compounded of both, and at the same moment a two-fold display of luxury; for as soon as ever people have succeeded in obtaining the conchyliated colour, they immediately begin to think that it will do better as a state of transition to the Tyrian hues. There can be little doubt that this invention is due to some artist who happened to change his mind, and alter a tint with which he was not pleased: hence a system has taken its rise, and spirits, ever on the rack for creating wonders, have transformed what was originally a blunder into something quite desirable; while, at the same time, a double path has been pointed out to luxury, in thus making one colour carry another, and thereby become, as they say, softer and more mellow. And what is even more than this, human ingenuity has even learned to mingle with these dyes the productions of the earth, and to steep in Tyrian purple fabrics already dyed crimson with the berry of the kermes, in order to produce the hysginian [From the Greek ὕσγινος, after the herb hysge, which was used in dyeing. Judging from the present passage, it would almost appear to have been the colour now known as puce. See B. xxi. c. 36 and c. 97; and B. xxxv. c. 26.] tint. The kermes of Galatia, a red berry which we shall mention when we come to speak [See B. xvi. c. 8, and B. xxiv. c. 4.] of the productions of the earth, is the most esteemed of all, except, perhaps, the one that grows in the vicinity of Emerita, [See B. iv. c. 35.] in Lusitania. However, to make an end, once for all, of my description of these precious dyes, I shall remark, that the colour yielded by this grain [This is in reality the Coccus ilicis of Linnæus, a small insect of the genus Coccus, the female of which, when impregnated, fastens itself to a tree from which they derive nourishment, and assumes the appearance of a small grain: on which account they were long taken for the seeds of the tree, and were hence called grains of kermes. They are used as a red and scarlet dye, but are very inferior to cochineal, which has almost entirely superseded the use of the kermes. The colour is of a deep red, and will stand better than that of cochineal, and is less liable to stain.] when a year old, is of a pallid hue, and that if it is more than four years old, it is quickly discharged: hence we find that its energies are not developed either when it is too young or when old.

I have now abundantly treated of an art, by means of which men, just as much as women, have an idea that their appearance may be set off to the greatest possible advantage.

Chap. 66. (42.)—The Pinna, and the Pinnotheres.

Belonging to the shell-fish tribe there is the pinna [Or pina. The Pinna marina, Cuvier says, is a large bivalve shell-fish, which is remarkable for its fine silky hair, by means of which it fastens itself to the bottom of the sea.] also: it is found [The poet Oppian, Halieut. B. ii. l. 186, relates the same story about the pinna and its protector; which is also mentioned by Cicero, Plutarch, and Aristotle.] in slimy spots, always lying upright, and never without a companion, which some writers call the pinnotheres, [We have already had an account of one pinnotheres, in c. 51. Some of the editions, however, make a difference in the spelling of the name, and call the animal mentioned in the 51st Chapter, “pinnotheres,” and the one here spoken of, the “pinnoteres,” the “guardian of the pinna;” from the Greek verb τηρέω, “to keep,” or “guard.” “Pinnophylax” has the same meaning.] and others, again, pinnophylax, being a small kind of shrimp, or else a parasitical crab. The pinna, [Cuvier says, that in the shell of the pinna, as, in fact, of all the bivalves, there are often found little crabs, which are, as it were, imprisoned there; and that it is this fact that has given rise to the story of the treaty of amity between these two animals, which appears in various authors, and is related in various forms, which only agree in being devoid of truth. Cuvier says that a careful distinction must be made between the pinnotheres of this Chapter, the one of which Aristotle makes mention, and that which is mentioned by Pliny in c. 51, the hermit-crab of the moderns. There can, however, be but little doubt that they are different accounts of the same animal.] which is destitute of sight, opens its shell, and in so doing exposes its body within to the attacks of the small fish, which immediately rush upon it, and finding that they can do so with impunity, become bolder and bolder, till at last they quite fill the shell. The pinnotheres, looking out for the opportunity, gives notice to the pinna at the critical moment by a gentle bite, upon which the other instantly closes its shell, and so kills whatever it has caught there; after which, it divides the spoil with its companion.

Chap. 67.—The Sensitiveness of Water Animals; the Torpedo, the Pastinaca, the Scolopendra, the Glanis, and the Ram-fish.

Upon [The whole, nearly, of this Chapter is taken from Aristotle, B. v. c. 16.] reflecting on such facts as these, I am the more inclined to wonder at the circumstance that some persons have been found who were of opinion that the water animals are devoid of all sense. The torpedo [Plutarch speaks of this fish, in his “Treatise on the Instincts of Animals;” also Oppian, Halieut. B. ii. l. 62. The Raia torpedo of Linnæus, Cuvier says, has on each side of the body a galvanic organ, which produces an electric shock, similar to that communicated by the use of the Leyden vial. By this means it baffles its enemies, and drives them away; or else, having stupefied them, devours them at its leisure.] is very well aware of the extent of its own powers, and that, too, although it experiences no benumbing effects from them itself. Lying concealed in the mud, it awaits the approach of the fish, and, at the moment that they are swimming above in supposed security, communicates the shock, and instantly darts upon them: there is no delicate [Cuvier confirms this statement. The liver of the torpedo, he says, is very delicate eating, as, indeed, is that part in most of the ray genus.] morsel in existence that is preferred to the liver of this fish. And no less wonderful, too, is the shrewdness [Oppian, Halieut. B. ii. l. 86; Ælian, Hist. Anim. B. ix. c. 24; and Cicero, De Nat. Deor. make mention of this.] manifested by the sea-frog, [The Lophius piscatorius of Linnæus, the baudroie of the French. This is a fish, Cuvier says, with a large wide mouth, and having upon the top of the head moveable filaments, surmounted by a sort of membranous lashes. It seems that it is the fact that it buries itself in the sand, and then employs the artifice here mentioned by Pliny, for the purpose of attracting the fish that serve as its food.] which is known by us as the “fisher.” Stirring up the mud, it protrudes from the surface two little horns, which project from beneath the eyes, and so attracts the small fish which are sporting around it, until at last they approach so close that it is able to seize them. In a similar manner, too, the squatina and the rhombus [Or turbot. This fish, the Pleuronectes maximus of Linnæus, and the Squalus squatina of Linnæus, presents no sufficiently distinct filaments at the extremity of the fins to justify what Pliny says. But the word “rhombus,” Cuvier says, which ordinarily means the common turbot, here means the psetta of the Greeks, the Pleuronectes rhombus of Linnæus, which has the anterior radii of the dorsal fin separated, and forming small filaments. For an account of the psetta, see c. 24, p..] conceal themselves, but extend their fins, which, as they move to and fro, resemble little worms; the ray also does the same. The pastinaca, [The sting-ray, the Raia pastinaca of Linnæus. This fish, Cuvier says, has upon the tail a pointed spine, compressed and notched like a saw, which forms a most dangerous weapon. It is again mentioned in c. 72 of the present Book, under its Greek name of “trigon.”] too, lies lurking in ambush, and pierces the fish as they pass with the sting with which it is armed. Another proof of instinctive shrewdness is the fact, that although the ray is the very slowest of all the fish in its movements, it is found with the mullet in its belly, which is the swiftest of them all.

(43.) The scolopendra, [Aristotle, Hist. Anim. B. ii. c. 17, and B. ix. c. 51; Oppian, Halieut. B. ii. l. 424; and Ælian, Hist. Anim. B. vii. c. 35, make a similar statement as to the scolopendra.] which bears a strong resemblance [The animal, Cuvier says, which is here mentioned as the scolopendra, is in reality of the class of worms that have red blood, or annelides, such, for instance, as the Nereides of larger size. These having on the sides tentacles, which bear a strong resemblance to feet, and sharp jaws, might, he says, be very easily taken for scolopendræ. They have also a fleshy trunk, often very voluminous, and so flexible that it can be extended or withdrawn, according to the necessities of the animal. It is this trunk, Cuvier thinks, that gave occasion to the story that it could disgorge its entrails, and then swallow them again.] to the land insect which we call a centipede, if it chances to swallow a hook, will vomit forth all its intestines, until it has disengaged itself, after which it will suck them in again. The sea-fox [This fish, Cuvier says, was doubtless a species of squalus; which have the power, in consequence of the sharpness of their saw-like teeth, of cutting a line with the greatest ease. It is mentioned by Aristotle, B. ix. c. 52; Ælian, Var. Hist. B. i. c. 43; and Oppian, Halieut. B. iii. l. 144.] too, when exposed to a similar peril, goes on swallowing the line until it meets with a weak part of it, and then with its teeth snaps it asunder with the greatest ease. The fish called the glanis [The fish that has been previously mentioned in c. 17 of this Book, under the name of silurus.] is more cautious; it bites at the hooks from behind, and does not swallow them, but only strips them of the bait.

(44.) The sea-ram [“Aries.” The Delphinus orca of Linnæus. See c. of the present Book.] commits its ravages just like a wary robber; at one time it will lurk in the shadow of some large vessel that is lying out at sea, and wait for any one who may be tempted to swim; while at another, it will raise its head from the surface of the water, survey the fishermen’s boats, and then slily swim towards them and sink them.
