ANATOMY AND PHYSIOLOGY 
OP ..THE SEXUAL ORGANS. 
“ The sexual organs in both sexes of this order of 
animals come nearer in form to those of the ruminating 
than of any others, and this similarity is perhaps more 
remarkable in the female than in the male, for their 
situation in the male must vary on account of external 
form, as was before observed. The testicles retain the 
situation in which they were formed, as in those 
quadrupeds in which they never come down into the 
scrotum. They are situated near the lower part of the 
abdomen, one on each side, upon the two great depressors 
of the tail. At this part of the abdomen the testicles 
come in contact with the abdominal muscles anteriorly. 
The vasa defferentia pass directly from the epididymus 
behind the bladder, or between it and the rectum, into 
the urethra, and there are no bags similar to those called 
vesiculae seminales in certain other animals. The struc- 
ture of the penis is nearly the same in them all, and 
formed much upon the principle of the quadruped. It 
is made up of two crura, uniting into one corpus caver- 
nosum, and the corpus spongiosum seems first to enter 
the corpus eavernosum. The glans does not spread out 
as in many quadrupeds, but seems to be merely a plexus 
of veins covering the anterior end of the penis, yet is 
extended a good way further on, and is in some not 
more than one vein deep. The crus penis are attached 
to two bones, which are nearly in the same situation, 
and in the same part of the pelvis as those to which the 
penis is attached in quadrupeds ; but these bones are
