I shall never cease to repeat (seeing the importance of the subject) that it is not by trivial particular characters we can judge of Nature, or distinguish the species; that methodical arrangements, far from elucidating the History of Animals, serve but to obscure it by multiplying unnecessary denominations and species; by making arbitrary genera which are not in Nature, and perpetually confounding real beings with imaginary creatures; by giving false ideas of the characteristics of the species, and mixing or separating them without foundation, without knowledge, and often without having seen a single individual. It is hence that our nomenclators constantly deceive themselves, and write almost as many errors as lines. We have already given so many examples of this, that he must be blindly prejudiced indeed, that can in the least doubt them. Monsieur Gmelin speaks very sensibly on this subject, when treating of the animal in question.[G] [G] Vide Voyage à Kamtschatka, par M. Gmelin. We are convinced, as M. Gmelin observes, that we cannot acquire a knowledge of Nature, but by making a judicious use of our senses, by reflecting, seeing, comparing, and, at the same time, by rejecting the bold freedom of forming methodical orders, and minute systems, in which animals are classed without the authors having seen them, and of which they are only acquainted with the names; names which are often equivocal, obscure, and misapplied. The wrong use of these names confounds the ideas in vague and indefinite words, and drowns the truth in a torrent of error. We are also convinced, after having compared the living mouflon with the description of M. Gmelin, that the argali is the same animal. We have said they are found in Europe, and in warm countries, such as Greece, the island of Cyprus, Sardinia, and Corsica; nevertheless, they are found also, and in great numbers, in all the mountains of the southern parts of Siberia, under a climate rather cold than temperate, and where they appear even to be bigger, stronger, and more vigorous. He might, therefore, have stocked the north and south parts, and his posterity have become domestic; after having long endured the rigours of this condition, he might have degenerated, taking relative characters, and new habits of body, according to the different climates, and the different treatments he has received; which being afterwards perpetuated by generation, have given rise to our domestic, and all other kinds of sheep, of which we have heretofore spoken. _Engraved for Barr's Buffon_ [Illustration: FIG. 141. _Barbary Wedder._] [Illustration: FIG. 142. _Ram of Tunis._] SUPPLEMENT.
