And I must here observe, that if there is any precision in the definition of Linnæus, this animal does not answer to it, either in the cauda recta or annulata, for he never carries his tail erect, but always close behind him like a dog when afraid, or unless when he is in full speed; nor is the figure given by M. de Buffon marked like the hyæna of Atbara, though, as have I said, perfectly resembling that of Syria, and the figure I have here given has, I believe, scarcely a hair misplaced in it. Upon the whole, I submit this entirely to my reader, being satisfied with having, I hope, fully proved what was the intent of this dissertation, that the saphan is not the hyæna, as Greek commentators upon the scripture have imagined. [Illustration: _Jerboa._ _London Published Dec^r. 1.^{st} 1789. by G. Robinson & Co._] JERBOA. I have already observed that the Arabs have confounded the Saphan with several other animals that have no sort of resemblance to it; there are two of these very remarkable, the Fennec and Jerboa, of which I am now to treat. As I have given excellent figures of both, by drawings taken from the creatures alive, I have no doubt I shall prevent any confusion for the future, and throw some light upon sacred scripture, the greatest profit and use that can result from this sort of writing. If the rabbit has been frequently confounded with the saphan, and stood for it in the interpretation of the Hebrew text, the same has likewise happened to another animal, the Jerboa, still more dissimilar in form and in manners from the saphan, than even the rabbit itself, and much less known. The Jerboa is a small harmless animal of the desert, nearly the size of a common rat: the skin very smooth and shining, of a brown tinged with yellow or gold colour, and the ends of the hairs tipt with black. It lives in the smoothest plains or places of the desert, especially where the soil is fixed gravel, for in that chiefly it burrows, dividing its hole below into many mansions. It seems to be apprehensive of the falling in of the ground; it therefore generally digs its hole under the root of some spurge, thyme, or absinthium, upon whose root it seems to depend for its roof not falling in and burying it in the ruins of its subterraneous habitation. It seems to delight most in those places that are haunted by the cerastes, or horned viper. Nature has certainly imposed this dangerous neighbourhood upon the one for the good and advantage of the other, and that of mankind in general. Of the many trials I made, I never found a Jerboa in the body of a viper, excepting once in that of a female big with young, and the Jerboa itself was then nearly consumed.
