74 THEPHILOSOPHY 



The tefticles of the male are fituated on each fide of the back- 

 bone, and are very large in proportion to the fize of the animal. 

 From the tefticles proceed two feminal du£ts, which at firfl: are 

 ftraight, but afterwards acquire a convoluted form, as in the epidy- 

 dymus of man. Thefe duds terminate in the penis, of which the 

 cock has two, one on each fide of the common cloaca. They are 

 very fmall and fliovt ; and, from this circumftance, they long efcaped 

 the notice of anatomifts. 



In the female, the clufter of yolks, being analogous to the human 

 ovaria, are attached to the back-bone by a membrane- This mem- 

 brane is very thin, and continues down to the uterus. The yolk, 

 after feparating from its ftalk, pafles into a canal called the infundi- 

 huluniy where it receives a gelatinous liquor, which, with what it 

 farther acquires in the uterus, compofes the white of the egg. The 

 uterus is a large bag, fituated at the end of the infundibulum, and 

 is full of wrinkles on the infide. Here the egg receives it laft co- 

 vering, or fhell, and is pufhed out of the vagina at an aperture pla- 

 ced immediately above the anus. 



From this defcription of the ftrudure of granivorous birds, the 

 analogy between them and the herbivorous quadrupeds is confpi- 

 cuous. In both, the number of their ftomachs, the length and ca- 

 pacity of their inteftines, and the quality of their food, are very fi- 

 milar. But this analogy is not confined to ftrudure and organs : It 

 extends to manners and dii'pofitions. Like the herbivorous quadru- 

 peds, this order of birds are diftinguiihed by the gentlenefs and com- 

 placency of their tempers. Contented with the feeds of plants, or 

 fmall infeds, the ftronger never wage war with the weaker. Their 

 chief attention is occupied in procuring food, in hatching and rear- 

 ing their young ; and their vigilance is kept perpetually a<5tive in 

 eluding the fnares of men and other rapacious animals. The whole
