GENERAL CONSIDERATIONS. 



ENUMERATION AND CLASSIFICATION OF THE SPECIES OF DOMESTICATED 



ANIMALS. 



The object of this book is the study of veterinary anatomy. The 

 animals of which it treats belong to the mammiferous class and to that of 

 birds. 



The domesticated mammals of our regions have their representatives in 

 a large number of orders. Thus, we find among them : — 



1. Of the carnivora, the Doc/ and Gat; 



2. A rodent, the Bahbit ; 



3. A pachyderm, the Pig ; 



4. Of solipeds, the Horse and Ass ; the produce of the male ass with 



the mare, i.e., ±he Mule, and that of the horse with the female ass, 

 known by the name of Sinny ; 



5. Of ruminants, the Ox, Sheep, and Goat. 



With regard to poultry, they range themselves :— 



1. In the gallinaceous order, the genera to which the common fowl, 



guinea fowl, turkey, &ndi pigeon belong ; 



2. In the order of palmipeds, the geese and ducks. 



Girard has proposed a special classification for the domesticated mammals 

 based upon the number of digits terminating each of their limbs, and has 

 defined four categories: the first comprises the horse, ass, mule, and hinny 

 which take the name of monodactyles, because their digital region is composed 

 ot a single digit ; in the second, under the denomination of didactvles or 

 fciSMZcafe animals, those with two digits, such as the ox, sheep, and goat ■ in 

 the third, or regular tetradactyles, is found ranged the pig, each of whose 

 limbs shows four digits; lastly, the dog and cat, which most frequently 

 have four digits on the posterior members and five on the anterior ones, and 

 lorm the class of u-regular tetradactyles.
