568 PHILOSOPHICAL TRANSACTIONS. [aNNO J 7 10. 



were involved within a duplicature of the peritonaeum, so that I had much ado 

 to get them separated. 



Having given an account of the parts of generation in the female, I shall 

 add Dr. Moulins' account of those in the male, with my own thoughts about 

 them. In searching for the testes, he found two muscles very like them, which 

 he supposed to have been them, till he had traced them to the inner and lower 

 side of the ischion, where he found them implanted; he traced the tendons 

 likewise, and found, that when they had gone singly near 4 inches, they joined 

 in one, which went directly under the middle of the penis, and reached beyond 

 a crookedness he observed in it. This was in length about 8 inches, and ter- 

 minated within 6 or 7 inches of the glans, having expanded itself into a mem- 

 brane. There was beside these a nervous body, that began underneath near 

 the aforesaid tendons, about 8 inches from the root of the penis, and reached 

 (distinct from the yard) Q inches, before it was inserted again in it, at a place 

 5-f inches from the glans. He is of opinion, these muscles in that nervous body 

 being so conveniently placed for that purpose, that the elephant is a retromin- 

 gent, and probably retrocoient animal; which I cannot. agree to. 



The testes, he says, were not contained in a scrotum or capsula, but lay in 

 the perinaeum, close joined on each side to the penis. They were neither of 

 the usual shape nor size, nor included in a processus of the peritonaeum. Their 

 shape was very like that of a chesnut, thicker on the side that grew to the penis 

 than on the opposite; they were flat and round, and not suitable to the other 

 parts of the body, being no more than about 3 or 4 ounces in weight. They 

 were joined to the penis by a great many, at least 100 seminal tubes, which may 

 be properly called vasa deferentia, and which deposited the elaborated semen in 

 several rhomboid cells, placed in the body of the penis, which in this creature 

 was the common and only repository, where the seed could be found. These 

 cells were turgid with sperm, and so were the tubes; the latter were very large, 

 but being pursued further into the body of the testes, they became smaller and 

 smaller till they disappeared. The blood came into the testes by the vasa defe- 

 rentia. 



Though these were small and disproportionable, yet he took them to be the 

 testes, nothing else outwardly appearing that contained seminary vessels, till he 

 understood by Dr. Needham, that his description of the testes of the elephant 

 agreed with the prostatas of a bear: on which he mistook the testes for the 

 prostatas, there being a great resemblance between these animals; and having 

 found two substances between the kidneys and neck of the bladder, which 

 might very well be testes, and which, till he discoursed with that gentleman, he
