Part 6

In Tartary they have an animal called _czigithai_, which possibly is of the same species as the zebra, as the principal difference between them is in the colour; a difference which, we have repeatedly observed, may be occasioned by the varieties of the climates. This czigithai is common in the southern parts of Siberia, Thibet, Dauria, and Tartary. Gerbillan says they are to be met with in the country of the Mongoux and Kakas; that they differ from mules, and cannot be brought to carry burthens. Muller and Gmelin both assert that there are numbers of them in the countries of the Tongusians, who hunt them like other game: that they resemble a bright bay horse, excepting they have long ears, and a tail like a cow. It is probable that if they had compared him with the zebra they would have found a much greater resemblance. In the Petersburgh cabinet there are stuffed skins both of the zebra and czigithai; they differ very much in colour, but yet they may belong to the same, or nearly the same species. Besides there is no other animal in Africa but what is to be found in Asia, and, therefore, if these are different species the zebra alone would stand as an exception to that general rule. If the czigithai does not belong to the zebra species it may possibly be the onagre, or wild ass of Asia; which latter should not by any means be confounded with the zebra. According to all travellers there are various kinds of wild asses, and the onagre is supposed to rank at the head of them. The horse, ass, onagre, and czigithai, may form four distinct species; and if there are but three, it will remain uncertain whether the latter is an onagre or zebra. The onagre is said to exceed the horse in swiftness, and the very same remark is made of the czigithai. Let this particular fact be as it may, the horse, ass, zebra, and czigithai, belong to the same genus, and are only different branches thereof. From the two first being rendered domestic, mankind have received great advantages, and the two last being reduced to a similar state would, no doubt, prove likewise a useful acquisition.

THE HIPPOPOTAMUS.

Though the Hippopotamus has been celebrated from the earliest ages; though mentioned in the sacred writings under the name of _behemoth_, and though his figure is engraved upon the obelisks of Egypt, and on the Roman medals; yet he was but imperfectly known to the ancients. Aristotle scarcely mentions him, and in the little he does say, there are more errors than facts. Pliny copied Aristotle, and far from correcting, adds to the number of his errors. It was only towards the middle of the sixteenth century that we had any precise information concerning this animal; Belon being then at Constantinople, saw a living one; of which, however, he has given but an imperfect representation, for the two figures which he has joined to his description, were not taken from the hippopotamus he has seen, but were copied from the reverse of a medal of the Emperor Adrian, and from the colossus of the Nile at Rome; so that we must carry the epoch of the knowledge of this animal to the year 1603, when Frederico Zerenghi, a surgeon of Narni, in Italy, printed at Naples, the history of two of these animals, which he had killed in Egypt, in a great ditch he had caused to be dug in the environs of the Nile, near Damietta. This little work was written in Italian, and appears to have been neglected by his contemporary and succeeding naturalists; notwithstanding, it is the only good and original one on the subject, and has so strong pretensions to credit, that I shall here give an extract and translation from it.

"With a view of obtaining an hippopotamus, (says Zerenghi) I suborned the people about the Nile, (who had seen two of these animals come from the river) to dig a large pit in the place where they passed over, and to cover it with light wood, earth, and grass. Returning in the evening to the river, they both fell into the pit. The people came immediately and acquainted me with the event, and I hastened thither with my Janissary. We killed both the animals by firing three charges from a large arquebuse into each of their heads. They expired immediately, uttering a doleful cry, which more resembled the bellowing of a buffalo, than the neighing of a horse. This exploit was performed on the 20th of July, 1600. The following day I had them drawn out of the pit, and skinned with care; the one was a male and the other a female. I had both the skins salted, and filled with the leaves of the sugar cane, in order to transport them to Cairo, where I had them salted a second time with greater attention and more convenience. In doing of which we used near 400lbs. of salt to each skin. At my return from Egypt, in 1601, I brought these skins to Venice, and from thence to Rome. I shewed them to many learned physicians. Doctor Jerome Aquapendente and the celebrated Aldrovandus, were the only persons who knew them to be the skins of the hippopotamus; and as the work of Aldrovandus was then printing, he had (with my consent) a figure drawn from the skin of the female, which he has given with his book.

"The hippopotamus has a very thick and hard skin; it is impenetrable, unless it be soaked some time in water: the mouth is not, as the ancients have said, of a moderate size, but enormously large; neither are his feet as they say, divided into two hoofs, but into four. His size is not that of an ass, for he is much bigger than the largest horse, or buffalo; he has not a tail like that of the hog, but rather that of the tortoise, except being incomparably larger; his mouth or nose is not elevated, but resembles that of the buffalo, and is much larger; he has no mane like the horse, but only some short hairs; he does not neigh like the horse, but his voice is between the bellowing of the buffalo, and the neighing of the former. His teeth do not jut out of his mouth, for when it is shut, the teeth, although extremely large, are all hid under the lips. The inhabitants of this part of Egypt call him _foras l'bar_, which signifies a _sea-horse_. Belon is much deceived in his description of this animal, he attributes to him teeth like those of a horse, which would induce me to think he had never seen him, although, as he tells us he had, for the teeth of the hippopotamus are very large and very singular. To clear up every doubt and uncertainty, continues Zerenghi, I have here given the figure of the female hippopotamus; every proportion has been taken exactly after nature, as well as the measure of its body and limbs.

"The length of this hippopotamus, from the extremity of the upper lip to the beginning of the tail, is nearly eleven feet two inches.[O]

[O] This measurement is according, to Paris feet and inches.

"The circumference of the body is about ten feet.

"The height, from the bottom of the foot to the top of the back, is four feet five inches.

"The circumference of the legs near the shoulders is two feet nine inches; and taken lower, is one foot nine inches and a half.

"The height of the legs, from the bottom of the feet to the breast, is one foot ten inches and a half.

"The length of the feet, from the extremity of the nails, is about four inches and a half.--_Note._ I have taken the medium measure between the two that Zerenghi gives, for the length of the feet.

"The nails are as long as they are broad, being rather more than two inches.

"There is one nail on each toe, and four toes on each foot.

"The skin upon the back is nearly an inch, and that upon the belly about half an inch thick.

"The skin is so hard when dried, that it cannot be pierced by a musket shot. The people of the country make great shields of it, and cut it into thongs or kind of whips. On the surface of the skin there are a few very fine hairs of a greyish colour, and which cannot be perceived at first sight; on the neck there are some longer, but they are all placed one by one, more or less distant from each other; but on the lips they form a kind of mustachio: for there springs out ten or twelve of them from the same points; these hairs are of the same colour as the rest, they are only harder, thicker, and somewhat longer, though the longest is not more than half an inch.

"The length of the tail is rather more than eleven inches, and its circumference, taken at the beginning, is something more than a foot, and at its extremity, is two inches and upwards.

"The tail is not round, but from the middle to the end is flat, like an eel. Upon the tail and the thighs, there are some round scales of a whitish colour, broad as a French bean; these small scales are also seen upon the breast, the neck, and upon some parts of the head.

"The head, from the extremity of the lips to the beginning of the neck, is two feet four inches, and its circumference about five feet eight inches.

"The ears are two inches and near an half long, more than two inches in breadth, are a little pointed, and furnished on the inside with thick, short, and fine hairs, of the same colour as the others.

"The space between each angle of the eyes is two inches and upwards, and from one eyelid to the other, is one inch and one line.

"The nostrils are two inches four lines long, and little more than one inch broad.

"The mouth, when open, measures about one foot six inches; it is of a square form, and furnished with forty-four teeth of different shapes. All these teeth are so hard, that they strike fire with steel. The enamel of the canine teeth in particular, have this hardness; the interior substance being not so hard. When the hippopotamus keeps his mouth shut there are no teeth to be seen, for the lips, which are extremely large, completely cover them.

"In respect to the figure of this animal, it may be said to be constructed between that of the buffalo and hog, because it participates of both, except the incisive teeth, which have no resemblance to those of either of these animals. The grinders are a little like those of the buffalo or horse, but much larger. The colour of the body is dark and blackish. It is affirmed that the hippopotamus produces but one young at a birth; that he lives on fish, crocodiles, and even the flesh of dead bodies; however, he eats rice, grain, &c. though on considering his teeth, we should conclude that Nature had not made him for grazing, but for the destruction of other animals."

Zerenghi finishes his description by affirming that all the above measures were taken from the female hippopotamus, whom the male perfectly resembled, excepting that he was a third bigger in all his dimensions. It were to be wished that the figure given by Zerenghi had been as good as his description; but the drawing was not taken while this animal was living, but from the skin of the female. It appears also, that it was from this same skin preserved in salt, that Fabius Columna designed his figure; but the description Columna has given, is not so good as that of Zerenghi's, and he must be reproached for only quoting the name and not a word about the work of this author, though published three years before his own: he must also be accused of swerving from his description in many essential points, without giving any reason for it; for example, Columna says, that in his time, in 1603, Frederico Zerenghi brought from Egypt to Italy an hippopotamus preserved in salt, while Zerenghi himself says, he brought only the skin. Columna also gives to his hippopotamus thirteen feet in length, to the circumference fourteen, and the legs three feet and a half long; while the measures of Zerenghi makes the length of the body but eleven feet two inches, the circumference ten, and the legs one foot ten inches and a half, &c. We must not, therefore, rely on the description of Columna; nor excuse him upon the supposition that he took it from another subject; for it is evident, from his own words, that he made it from the smallest of Zerenghi's two hippopotami; since he acknowledges that some months after Zerenghi shewed a second hippopotamus much larger than the first. What makes me so strenuous on this point is, that no one has rendered justice to Zerenghi, who, notwithstanding, is the only person who deserves eulogiums on this subject. On the contrary, every naturalist, for this hundred and sixty years, have attributed to Fabius Columna what they should have given to Zerenghi; and instead of searching for the work of the last they have set down contented with copying and applauding that of Columna's, who, however deserving of praise in other respects is, upon this, neither original, exact, nor even honest.

The description and figures of the hippopotamus that Prosper Alpinus published more than a hundred years after, are still worse than those of Columna, having been drawn from skins but badly preserved; and M. de Jussieu, who wrote of the hippopotamus in 1724, has only described the skeleton of the head and feet.

By comparing these descriptions, and especially that of Zerenghi, with the information we have drawn from travellers, the hippopotamus appears to be an animal whose body is longer and as thick as that of the rhinoceros; that his legs are much shorter; that his head is not so long, but larger in proportion to his body: that he has no horns, either on the nose like the rhinoceros, or on the head like the ruminating animals. His cry when hurt, according to ancient and modern travellers, resembles the neighing of a horse and the bellowing of the buffalo; his usual voice may be like the neighing of a horse, from which, however, he differs in every other respect. If thus be the fact, we may presume that this resemblance in the voice has been the reason for giving him the name of _hippopotamus_, which signifies the _river horse_, as the howling of the lynx, which resembles that of the wolf, occasioned him to be called the _lupus cervarius_. The cutting teeth of the hippopotamus, and especially the two canine of the lower jaw, are very long, and so hard and strong that they strike fire with a piece of steel. This is probably what, gave rise to the fable of the ancients, that the hippopotamus vomited fire: these canine teeth are so white, so clean, and so hard, that they are preferable to ivory for making artificial teeth. The cutting teeth, especially those of the lower jaw, are very long, cylindrical and furrowed; the canine teeth are also very long, crooked, prismatic, and sharp, like the tusks of a boar: the grinders are square, or rather oblong, nearly like those of a man, and so large that a single one weighs more than three pounds; the largest of the cutting, and the canine teeth are twelve and even sixteen inches in length, and sometimes weigh twelve or thirteen pounds each.

In short, to give a just idea of the size of the hippopotamus we shall make use of Zerenghi's measures, increasing them one third, because his measures were taken from the female, who was one third less than the male in all her dimensions. This male hippopotamus was consequently sixteen feet nine inches long, from the extremity of the muzzle to the beginning of the tail; fifteen feet in circumference, and six feet and a half in height; his legs were about two feet ten inches long; the length of the head three feet and a half, and eight feet and a half in circumference ; the width of the mouth two feet four inches, and the largest teeth more than a foot long.

Thus powerfully armed, and with such prodigious strength of body, he might render himself formidable to every animal; but he is naturally gentle, and is besides so heavy and slow that he could not outrun any other quadruped. He swims quicker than he runs, pursues the fish, and makes them his prey. He delights much in the water, and lives in it as freely as upon land, yet he has no membranes between his toes like the beaver and otter, and it is plain, that the great ease with which he swims is owing to the great capacity of his body, which makes his specific gravity nearly equal to the water. Besides, he remains a long time under water, and walks at the bottom as well as in the open air; and when he quits it to graze upon land he eats sugar-canes, rushes, millet, rice, roots, &c. of which he consumes great quantities, and does much injury to cultivated lands; but as he is more timid on land than in the water he is very easily driven away, and his legs are so short that he cannot save himself by flight, if he be far from any water. His resource, when in danger, is to plunge into the water, and proceed under it to a great distance before he reappears. He commonly retreats from his pursuers, when hunted, but if wounded he becomes irritated, and faces about with great fury, rushes against the boats, seizes them with his teeth, tears pieces off, and sometimes sinks them. "I have seen, says a traveller,[P] an hippopotamus open his mouth, fix one tooth on the gunnel of a boat, and another on the second plank under the keel (that is at least four feet distant), pierce the side through and through, and in this manner sink the boat. I have seen one lying by the side of the sea-shore, upon whom the waves tossed a Dutch boat heavily laden, and then retreating left it dry on his back, and which was afterwards carried off again by another wave, without the animal appearing to have received the least injury. I could not discover the exact arrangement of his teeth, but they appear to form the figure of a bow, and were about sixteen inches long. We fired several times at one of them, but the shot rebounded from his skin. The natives consider him as a kind of deity, and that he cannot be destroyed, and frequently declare, if they were to use him as we do he would soon be the destruction of their nets and canoes. When they go a fishing in their canoes, and meet with an hippopotamus, they throw fish to him, and then he passes on without disturbing their fishery any more. He does the most injury when he can rest himself against the earth, but when he floats in the water he can only bite. Once, when our boat lay near the shore, I saw one of them get underneath, lift her above water upon his back, and overset her with six men aboard, but fortunately they received no hurt."----"We dare not, says another traveller, irritate the hippopotamus in the water, since an adventure that had nearly proved fatal to three men; they had proceeded in a small canoe to attack one in a river where there was about ten feet water; they discovered him walking at the bottom, according to his usual custom, and wounded him with a long lance, upon which he rose immediately to the surface of the water, looked at them with a dreadful aspect, and, at one bite, took a great piece out of the side of the canoe, which had very nearly overturned it, and it was with difficulty they could make the shore." These two examples are sufficient to give an idea of the strength of these animals; and a number of like facts are to be met with in the General History of Voyages, by the Abbé Prevost, who has given a summary of whatever travellers have reported concerning the hippopotamus.

[P] Dampier, vol. II.

These animals are not numerous, except in particular places, and it even appears that they are confined to the rivers of Africa. The greatest part of naturalists have said, that the hippopotamus is to be found also in the Indies, but the evidence they have of this circumstance is very equivocal; the most positive would be that of Alexander, in his letter to Aristotle, if we could assure ourselves, that the animals of which Alexander speaks, were really hippopotami. What occasions me to have some doubts on this head is, that Aristotle, in describing the hippopotamus in his history of animals, must have said, that they were natives of India, as well as Egypt, if he had thought that the animal, of which Alexander speaks in his letter, had been the true hippopotamus. Onesicritus, and some other authors, say the hippopotamus is to be found in the river Indus, but modern travellers, at least those who merit most confidence, have not confirmed this fact; they all agree, that this animal is found in the Nile, the Senegal, or Niger, the Gambia, the Zara, and other great rivers and lakes of Africa, especially in the southern and eastern parts. Father Boyn is the only one who seems to insinuate that the hippopotamus is to be met with in Asia, but his recital appears suspicious, and I think only proves that he is common in Mosambique, and all the eastern parts of Africa. At present the hippopotamus, which is called the _Nile-horse_, is so rare in the lower Nile, that the inhabitants of Egypt have no idea of the name. He is equally unknown in all the northern parts of Africa, from the Mediterranean to the Bamboo river, which flows at the foot of Mount Atlas; the climate which the hippopotamus actually inhabits, therefore extends only from Senegal to Ethiopia, and from thence to the Cape of Good Hope.

As most authors have called the hippopotamus the _sea-horse_, or _sea-cow_, it has sometimes been confounded with the latter, which is a very different animal, and which only inhabits the northern seas. It appear, then, to be certain, that the hippopotami, which the author of the description of Muscovy says are found upon the borders of the sea of Petzora, are no other than sea-cows, and Aldrovandus merits reproach for adopting this opinion without examination, and asserting that the hippopotamus is found in the northern seas: for he not only does not inhabit the north seas, but it appears that he is rarely found in those of the south. The testimonies of Odoardus, Barbossa, and Edward Wotton, recounted by Aldrovandus, and which seem to prove that the hippopotamus inhabits the Indian seas, appear to be almost as equivocal as that in the description of Muscovy; and I am inclined to believe that the hippopotamus is not to be found, at least at present, but in the greatest rivers of Africa. Kolbe, who says, he has seen many of them at the Cape of Good Hope, affirms, that they equally plunge themselves into the sea and rivers, and which is asserted by other authors. Although Kolbe appears to be more exact than common in his description of the hippopotamus, yet it is doubtful whether he saw it so often as he says, since the figure he has joined to his description is worse than those of Columna, Aldrovandus, and Prosper Alpinus, which are all drawn from stuffed skins. It is easy to discover that the figures and description in Kolbe's works, have neither been made on the spot, nor taken from Nature. His descriptions are written from memory, and most of the figures been copied from those of other naturalists; the figure which he gives of the hippopotamus, in particular, bears a great resemblance to the cheropotamus of Prosper Alpinus.

Kolbe, therefore, in affirming, that the hippopotamus lives in the sea, might possibly have copied Pliny, and not spoken from his own observations. Most other authors tell us, that this animal is only to be found in the fresh water lakes and in rivers, sometimes at their mouths, but oftener at a great distance from the sea. There are even travellers, who, like Merollo, are surprised, that the hippopotamus should have been called the sea-horse, because, say they, this animal cannot bear salt water. He commonly remains all day under water, and only quits it at night to graze upon land. The male and female rarely separate. Zerenghi caught both male and female the same day, and in the same ditch. Dutch travellers say, that they bring forth three or four young at a time, but this fact appears to me very suspicious from the evidence which Zerenghi has mentioned. Besides, as the hippopotamus is of an enormous bulk, he is in the class of the elephant, rhinoceros, whale, and all other large animals, who bring forth but one at a time; and this analogy appears to me more certain than all the suppositious testimonies of different travellers.
