ANATOMY OF THE STOMACH. 59 



contracted, or at the distance of six inches from 

 the pylorus, after which it dilated to twelve 

 inches, and then contracted again at the pylorus, 

 to four and a half inches. This cavity at the 

 left extremity was of about a uniform size 

 throughout the first five inches, but there was 

 not the slightest appearance of a separate cavity 

 as generally described, and as is strongly repre- 

 sented by Home in the Bactrian camel ; other- 

 wise the form of this third cavity corresponded 

 perfectly with his figure. He remarks upon the 

 intermediate cavity as so small that it might 

 be overlooked, were it not for the distinctness of 

 its orifices ; but this last was not found in either 

 of the individuals under description. He remarks, 

 also, upon the absence of septa and of the cuticle 

 which generally characterize the third cavity of 

 ruminants, and which absence, in the present 

 case, seemed to be a strong additional reason 

 for denying the existence of an intermediate 

 cavity. The mucous membrane generally was 

 smooth, soft, extremely thin, and thrown into 

 loose longitudinal folds, of which there were 

 counted about forty, commencing towards the 

 left extremity, where the dilatation began, and 

 terminating within six inches of the pylorus ; in 

 it were some small mucous follicles. Upon the
