BRAIX. 



Its brain is larger than thatof tlie ox, but smaller than that of the 

 horse. 



BUCCAL MUCOUS MEMBRANE. 



The buccal mucous membrane of the dromedary hangs in the 

 pharynx ; when the animal is rutting, or when it is greatly agitated, 

 that mucous membrane is expelled from the mouth with a loud noise, 

 produced by the air ; it presents wrinkles and folds sufficiently large 

 to form a pouch where the food remains during the act of rumination ; 

 on its surface that pouch is covered with papillae larger than those 

 of the ox. The mucous membrane of the tongue also contains nervous 

 papillae of remarkably irregular forms. 



NECK. 



The neck of the dromedary has on each side two veins and one 

 artery, as is the case with all the ruminating animals ; it is of a de- 

 formed length. 



TRACHEA. 



The trachea is formed by a tube, longer but not so large as those 

 of all the other animals ; the nostrils being also very narrow, it fol- 

 lows that the air has a small passage by which to arrive at the lungs, 

 the main organ of respiration. 



SUBSTANCE OF THE HUMP. 



The substance of the hump is greasy, and can be compared to that 

 of the udder of the cow. 



ANTERIOR WALL OF THE ABDOMEN. 



The anterior wall of the abdomen of the dromedary is much stronger 

 than that of other animals ; the white line which divides it into two 

 parts in the middle is very prominent. The muscles of that region 

 cross each other in the most solid manner. 



COMPARTMENTS OF THE STOMACH. 



The ox has his stomachic apparatus composed of four stomachs ; it 

 is the same case with the dromedary ; those of this last, although hav- 

 ing diiferent and better defined forms, can receive the same names. 

 We will content ourselves, nevertheless, with designating them by 

 their numbers of order. 



PAUNCH, OR FIRST STOMACH. 



In the cases of all the dromedaries which had died the evening be- 

 fore, we have remarked that the paunch, the first stomach of the ru-
