a Male and a Female Dromedary. 15 



wide, was apparently diseased ; about two-thirds of it occu- 

 pied by a cyst filled with a watery mucus, and lined by a 

 proper villous membrane ; in the remaining portion was a dark 

 grey cyst. 



In each of the Broad Ligaments were distinct, but scat- 

 tered and irregular, transverse muscular fibres. 



The Heart was about as larse as in the horse, and had the 

 same conical form. Auricles of a regular, rounded form, and 

 equal to about two and one-half or three inches square ; ap- 

 pendices not strongly marked ; muscular substance in the left 

 from two to three lines thick, but in the right it was thinner ; 

 fossa ovalis deep. In the female, the left ventricle was nine 

 inches long and the right seven and one-half, measuring on 

 the outside ; the left was ten lines thick at the upper extrem- 

 ity, then diminished to eight, increased again to twelve, and 

 at the apex was but two, without the fat, of which there was 

 some at that part ; the right was from two to four, averaging 

 about three ; inner surface of the left for the most part smooth. 

 Mitral valve divided into two distinct portions, and measured 

 along its adherent edge eight inches ; the tricuspid eight and 

 one-third. Pulmonary artery six inches transversely on the 

 inner surface, just above the valves, and one and one-half 

 lines in thickness ; ascending aorta four and one-half inches 

 and three lines thick. From the arch of the aorta there 

 arose two vessels, so near to each other as almost to have a 

 common origin ; one of these was the left subclavian ; the 

 other was the common trunk of the right subclavism and the 

 two carotids. The above measurements were taken from 

 the female ; the heart of the male was rather larger. 



The Trachea of the male had seventyone rings, ranging 

 from five to nine lines in width, and expanded posteriorly, so 

 as to overlap each other ; also overlapped so as to form more 

 than a complete circle, except at the lower extremity. Trans- 

 verse diameter inferiorly one and one-half inch, the antero- 

 posterior being rather less ; superiorly the flattening was lat- 

 eral. On the right side a large bronchus was given oil just 

 above the proper bifurcation. Muscular coat very strongly 

 developed, the fibres measuring one and one-fourth Jnch in
