In 1681, a year after Grew's publication, Luc Schrockius printed a history of this animal at Vienna, in which we do not find any thing very exact, nor absolutely new. We shall, however, select such facts as may be collected from it, and which agree with those in other authors, and especially in the works of the more modern travellers. We have been under the necessity of contenting ourselves with collecting what has been said of this animal, which we have never seen, and which we have not been able to procure. By Grew's description, which is the only authentic work we can rely on, it appears, that the hair of this animal is long and rough, the muzzle pointed, and the tusks somewhat like those of the hog: in these characters it approaches the boar kind, or perhaps still more the babiroussa, which the naturalists have denominated the _Indian boar_; and which, though resembling the hog in many characters, like the musk animal, he is much smaller, and has longer and slender legs, like those of the stag, or roe-buck. On the other hand, the American hog, which we have called _pecari_, has a bag, or cavity, on its back, containing an odoriferous humour. The musk animal has a similar bag, not on his back, but under the belly. In general, those animals which produce odoriferous liquors, as the badger, the bearer, the pecari, the musk-rat, the civet, the zibet, are not of the stag or goat genus: thus we might be tempted to think, that the musk animal is nearer the hog kind, of which he has the tusks, if he had, at the same time, incisive teeth in his upper jaw; but his deficiency in that respect, makes him come nearer the ruminating animals, and especially the chevrotain, which ruminates, though it has no horns; but all these external indexes can only furnish us with conjectures. It is the inspection of the internal parts alone that can decide the nature of this animal, which is not even as yet perfectly known; nor have I placed him after the goats and antelopes from any conviction or even reason to conclude he belongs to those species. Marco Polo, Barbosa, Thevenot, and Marini, are all more or less deceived in the characters they have given of this animal[AB]. The only true point in which they agree is, that the musk is formed in a bag, or tumour, near the navel, and it appears by their testimonies, as well as those of other travellers, that the male only produces the musk; that the female has a similar bag near the navel, but that the humour which gathers there, has not the same smell; that this tumour of the male is only filled with musk at the rutting-time, and that at other times the quantity of this humour is less, and the odoriferous scent much weaker. [AB] There exists in fact, says Sonnini, a variety of the musk animal which is entirely white. It is however very rare. Pallas saw a female of this variety which came from the country of the Abakanks. _See Pallas, vol. iv. p. 14._
