Such is the whole information which we have been able to acquire concerning the different species of gazelles, and their natural dispositions and habits. Let us now see how far naturalists have been right in attributing the production of the oriental _bezoar_ to one kind of those animals only; and whether this animal be really the _pasan_ or _pazan_, which they have described by the name of the _bezoar gazel_. In examining the description and the figures of Koempfer, who has written a great deal on this subject, it is doubtful whether he means that the pazan or the algazel is the only animal which produces the oriental bezoar. If we consult other naturalists and travellers, we shall be tempted to believe that this stone is the production not only of gazelles but of wild and domestic goats, and even sheep, the formation of which probably depends more on the temperature of the climate, and the quality of the food, than on the nature or the species of the animal. If we believe Rumphius, Seba, and some other authors, the true oriental bezoar is the production of apes and not of gazelles, goats, or sheep. But this opinion of Rumphius and Seba is not founded, for we have seen many of these concretions, to which the name of ape bezoar has been given, but they are quite different from the oriental bezoar, which is certainly produced by a ruminating animal, and is easily distinguished from all other bezoars by its shape, substance, and colour, which is generally that of an olive, and brown within, while the _occidental_ bezoar is of a pale yellow. The substance of the first is soft and porous; that of the last hard, dry, and as it were petrified. Besides, as prodigious quantities of the oriental bezoar was consumed in the last century; and as it was used in Europe and Asia for all cases in which our present physicians give cordial medicines, and antidotes against poison, may we not presume, from the great quantities which were formerly, and are still, in some degree, consumed, that this stone is produced, not from a single species of animal but from many, and that it is equally the production of gazelles, goats, and sheep, who cannot produce it but in certain climates of the Levant and Indies.
