298 GENERATIVE SYSTEM. 



tomy, a name it hardly merits in this instance. It has a celhilar 

 arrangement internally, which we may regard in the same light 

 as the spongy structure of the glans itself: indeed, if I might 

 be allowed here to draw a comparison between these parts in a 

 man and in a horse (the spongy body being more developed in 

 the penis of the former, the glans in that of the latter), I should 

 say, that the glans was an expansion of the corpus spongiosum, 

 and that the glans in the horse and the corpus spongiosum in 

 man bore strong evidence of some peculiar venous arrangement. 



OF THE PROSTATE GLANDS. 



These bodies are three in number: a single large one situated 

 around the neck of the bladder, corresponding to the gland of the 

 same name in the human subject ; and two small ones, which 

 answer in situation to two little glandular bodies occasionally met 

 with in man, named, from their discoverer, Coivper's glands. 



THE GREAT PROSTATE embraces the neck of the 

 bladder and incipient portion of the urethra, both superiorly 

 and laterally, being placed between those parts (by which it 

 is supported) and the rectum. It is firmly attached to the 

 parts it surrounds by cellular tissue; and has also a cellular 

 connexion in front with the vesiculae seminales, and above with 

 the rectum. We distinguish in this gland two lateral lobes, 

 and a uniting middle portion ; which, in man, Sir E. Home 

 has described as the third lobe, in consequence of its assuming 

 frequently the lobular form when in a state of disease. The lobes 

 are envelojied in incompact cellular cases, have exteriorly a con- 

 glomerate disposition, and are of a palish brown colour. Internally, 

 they possess a spongy or cellular structure, diffused through 

 which are sets of thin membranous tubes, very large for the size 

 of the gland, which are readily inflated, and then are seen to 

 open, through orifices before described, around the base of the 

 verumontanum. The gland secretes a whitish liquor resembling- 

 thin mucus, and this mingles with the sperm at the time of its 

 ejection ; but for what particular purpose has not been satisfac- 

 torily determined. 



THE LESSER PROSTATES are situated against the 

 sides of the urethra, contiguously to the posterior part of the 

 bulb, where they lie upon the branches of the ischium. Each 

 of them is about equal in bulk to one of the lateral lobes of 

 the large prostate. They are included in loose cellular sheaths, 

 that are continuous with the substance of the triangular mus- 

 cle. In figure, they are flattened ovals. In colour, they are 

 likewise a pale brown; but it is a lighter shade still than
