ORDER V. THE CAKXIVORA. 

 The BuTciiEinxG and Flesii-eatinc Animals. 



The dcntiti(jn of tiicse animals harmonizes with their sanguineous appe- 

 tite, furnishing tlie instruments neeessarv for its gratification. Tlicy have, 

 invarialily, four stout and long separated canines, between which arc six 

 incisors to each jaw, of which the second inferior arc inserted a little moi-c 

 iiiwai-d than tlic rest. The molars are either entirely trenchant, or ha\e 

 some blunted tuberculous parts, but have no sharp conical projections. 

 The appetite for tlesh and blood is stronger in proportion as the teeth are 

 more exclusively trenchant; and by a comparison of the tubercular surface 

 of the teeth with the cutting portion, may be determined the degree to 

 which the carnivorous proi)cnsity pre\ails in animals. The anterior molars 

 arc the most trenchant ; next follows a molar larger than the others, which 

 has usiiallv a tuberculous projection diU'cring in size ; and then billow one 

 or two smallr-r teeth that are entirely ilat. It is with these latter that the 

 dog chews the herbs wdiich he sometimes swallows. 



Cuvier designates this large upper molar and the op[)ositc one below 

 C((ri)ir<ir<ii(s teeth ; the anterior [)ointed ones, falxe molars, and the posterior 

 blunt ones liilnTvuloiis luahirs. Those genera ■which have the shortest 

 jaws are best adapted for biting. 



The hinil I'eet also rcrpiire examination. Some I'cst the whole sole on the 

 ground when walking, ^\hich circumstance is generally indicated by the 

 aljscnce of fur on that part. These are called I'liiiitiijradvs. Other gen- 

 era walk on the toes, witli the tarse elevated. These ha\e a more rapid 

 gait, and are called Itlij'diijrudvfi. To this primary difference are added 

 many others in the habits and even internal conformation of animals. 



This Order is divided into six families, at the head of which we prefer to 

 place the 



CANID.Ti — The Dogs.
