The horns of the giraffe being solid, and their substance similar to those of the stag, there could be no doubt of his ranking in the same genus, especially if he sheds his horns annually of which, however, we are still uncertain; but we may safely assert he ought to be separated from that of the ox, and all those animals whose horns are hollow; and, indeed, until the contrary be proved to be the fact, we cannot do otherwise than consider the giraffe as a peculiar species, in the same manner as the elephant, rhinoceros, the hippopotamus, forming a species which has no collaterals, and which seems to be a privilege conferred by Nature simply on those which are of the largest magnitude. In the description of M. Allemand we freely acknowledge that he has displayed much accuracy, and a perfect intimacy with the subject; but yet I apprehend that the longest of the horns he did me the favour to transmit does not belong to a giraffe, for the short one is very thick, and that quite thin, comparatively with their different lengths. In an anonymous description which I received from Holland of this animal it is stated, that the horns of a full-grown giraffe are a foot long, and as thick as a man's arm; according to which the horn we are now considering being six inches long, it ought to be full twice as thick, as it is, in reality; and, indeed, it so perfectly resembles the first horns of a young stag, that we can have little doubt of its belonging to that animal. As to the nature of the giraffe's horns I feel no hesitation in coinciding with the opinion of M. Allemand. The protuberance on the front is osseous, and may be considered as a third horn; and as the horns adhere to the cranium, they should be considered as osseous prolongations of the head. In short the horn of the giraffe appears to be a bone, differing from that of the ox by its covering, the latter being entirely surrounded with a horny substance, and the former with hair and skin.
