which runs a groove leading from the clitoris to the vagina. Between 

 these two labia passes in the common vagina 1 , about an inch in length : 

 then begins the true vagina, at the mouth of which is the meatus 

 urinarius, and a sort of hymen or caruncula myrtiformis. The vagina 

 is pretty much like that of the human. The clitoris is pretty long, 

 and its end prominent, which is a little bifurcated. The plexus reti- 

 formis is much as in the human 2 . 



[The Wanderoo (Macacus Silenus, Linn.).] 



In another large one [full-grown] that I examined at the same time, 

 I found only these differences. There were not the two swellings on 

 the sides of the clitoris, nor was the clitoris so long ; but instead of 

 swellings there was a kind of prepuce that surrounded the clitoris, but 

 it was very 'long and wide ; and as the clitoris was not so long nor 

 so protuberant, they did not lie so far on ossa pubis. 



The bladder was not so pendulous. The pubis was larger, so that 

 its contents was more as in the human subject to appearance. There 

 was not the least sign of an appendix caeci. The caecum was as in the 

 human. 



The length of the animal was 3 feet ; the small intestines 8 feet ; the 

 great intestines 4 feet, which is four lengths of the animal. 



The heart is more like that of the human, that is, not so round, broader 

 at its basis, and more obtuse at its point. The hearts of both speci- 

 mens were pretty much fasciculated, as in the human. 



[The Brown Monkey (Macacus nemestrinus,IArm. 3 ).~\ 



In a pretty large male monkey I observed the digastric muscle ; and 

 in this animal it seems clear that the posterior belly depresses the lower 

 jaw, for it makes but a very little angle with the anterior belly. 



There was a cartilage on each side loosely fixed to the root of the 

 arytenoid cartilage, where the sacculus laryngis is fixed, passing up 

 to the rimula laryngis, making a point between the epiglottis and the 

 point of the arytenoid cartilage : this is a little more like [the larynx of J 

 the dog than [of] other animals. There was a congeries of small 

 glandular bodies placed in a row under the tongue, and in its direction 

 making a small protuberance along the surface : I imagine these to be 

 similar to the [part called the] ' worm* [in the dog]. 



The heart was pretty much like the human, but with not so much of
