There are examples in every language, of two different names being applied to the same animal, one of which has a relation to its wild state, and the other to its domestic. The wild boar and the hog are the same animal, under two names, no ways relative to any difference in their natures, but to the condition of the species; one part of which is under the power of man and the other independent. It is the same with respect to the lamas and the pacos, which were the only domestic animals of the ancient Americans: these names belonged to them in their domestic state. The wild lama was called huanacus, or guanaco; and the wild pacos, vicuna, or vigogne.[AJ] I conceived this remark necessary to avoid the confusion of names. These animals are to be found only in he New World: they seem even to belong to some particular parts, beyond the limits of which they are never to be seen. They appear confined to that chain of mountains which stretches from New Spain to Terra Magellanica: they inhabit the highest regions of the globe, and seem to require a purer and more refined air than that of our highest mountains. [AJ] The Peruvians yet call the lama by the name of _runa_, which signifies sheep. _Lama_ is a generic word signifying _animal_, _brute_, and at this day they understand by the word _runa llasna_, an Indian sheep. A modern traveller observes, that the _guanaco_, and the _chillebueque_ are animals quite distinct from the _lama_. It is therefore improperly that these names are found among these cited by Buffon as applied to the _lama_. It is singular, that although the lama and the pacos are domestic in Peru, Mexico, and Chili, like the horses in Europe, or the camels in Arabia, we scarcely know any thing of them; and notwithstanding the Spaniards have had possession of those vast countries for above centuries, not one of their authors have given us complete histories, nor an exact description of these animals, which they are using every day! It is pretended indeed, that they cannot be transported into Europe, nor even be brought from their heights, without, at least, risking their lives in a short time; but at Quito, Lima, and many other towns, where persons of literature reside, they might have designed, described, and dissected these animals. Herrera says but very little about them, and Garcilassa only speaks from other authors. Acosta and Gregoire de Bolivar have made the greatest collections of facts relative to the natural dispositions of lamas, and the advantages to be derived from them; but they have left us in the dark as to their interior conformation, and of the length of time they go with young; whether the lama and the pacos are two species absolutely separate from each other; whether they mix together, or whether there are any intermediate breed, and a number of other facts necessary to render their history complete.
