Penis. This organ ii free, and is suspended in front of the pubis. It is enveloped 

 by a fibrous covering t he superficial fascia, and a cutaneous cylinder the sin-ill h. It is 

 attached by two supensory ligaments : the superficial is elastic, and ari.-es Ir-'iu the lim-a 

 alba; the deep is inelastic, and is detached from the >ymphy.-is pubis and ti.c anterior 

 pillar of t!se inguinal ring, (ft is Usual to describe only one ligament the //;/?< 0//u 

 tuspensorium penis, separating to form two layers which give pa -.-age to the dorsal 

 vessels, and nerves of the penis.) The ylans is separated from the n .-t of tin- on_ r an l.\ .-. 

 constriction designated the cervix, and around this the skin forms a (circular) ibid the 

 prepuce, which covers the glans more or less completely. It is attached to the middle of 

 its lower face by a thin fold the frienum prxputii. The inner surface of the prepuce 

 has a large number of sebaceous glands. 



CHAPTER II. 



GENITAL ORGANS OF THE FEMALE. 



THESE organs resemble those of the male in their general disposition. Thus 

 we find in the female : 1, Two secretory organs, the ovaries, analogous to 

 the testicles, and charged with the elaboration of the germ; '2, The u/r/-// 

 (Fallopian} tube, disposed, like tho epididymis and vas deferens, as a flexuous 

 canal, through which the ovum passes on leaving the ovary ; 3, The uterus, 

 a single reservoir formed of two lateral moieties which may be compared to 

 the vesiculre seminales, as it is there that the germ remains until it is fully 

 developed ; 4, The vagina, a membranous canal analogous to tho urethra, 

 and giving passage to the foetus after it has been formed in the uterus : this 

 canal, which receives the penis during copulation, also shows, at its exterior 

 opening, the vulva, an erectile apparatus, and the clitoris, which is nothing 

 more than a rudimentary corpus cavernosum of the male. The female lias 

 also certain glands, which, in many species, exist in a rudimentary form in 

 the male : for instance, tho mammse, organs for tho secretion of milk, the 

 first nourishment of the young animal. 



(The glands of Duverney, in the female vagina, seem to be analogous to 

 Cowper's glands in the male, as they are present in the females of all 

 animals where the latter exist in the male, and their secretion appears to bo 

 of the same character.) 



It may bo remarked, after this enunciation, that tho male and female 

 genital apparatus are constructed on the same type: a circumstance which is 

 most clearly demonstrated at an early period of intra-utr,rine life, wlieu it is 

 impossible to distinguish tho sexes.

 organs of generation in the female, aro two ovoid bodies, smaller than tho 

 testicles, though of the same shape, situated in the abdominal cavity, 1 and

 observed them, in four swine, occupying litil< ca\ it ics, analogous t<> tho.-e of the male
