fold receives the combined vesicular and seminal ducts, g } g. A 

 small style passed into it, as at/, penetrates a pyriform sac in the 

 middle lobe of the prostate, which is the rem- 

 nant of the protometra: it is exposed by 

 removal of the glandular covering, at e, fig. 

 533. Cowper's glands are rounded bodies, 

 about the size of an ordinary pea ; of a solid 

 texture, a palish red colour, and conglomerate. 

 The lobules are connected together by areolar 

 tissue, and are surrounded by a fibrous cap- 

 sule : they are composed of elongate follicles, 

 from the fiftieth to the twenty-fifth of a line 

 in length, and about the thirty-sixth of a line 

 in breadth. Their slender ducts, of about the eighteenth or six- 

 teenth of a line in diameter, usually coalesce into a single excre- 

 tory duct. The ducts of each gland run parallel for the distance 

 of half an inch beneath the mu- 

 cous membrane of the bulb, and 

 approaching each other, they 

 pierce the urethra by two ex- 

 ceedingly minute orifices. 



The penis consists of the erec- 

 tile tissues called e corpora caver- 

 nosa ' and c corpus spongiosum,' 

 the latter inclosing the urethra 

 and expanding at its hind end 

 into the 'bulb' and at its fore 

 end into the ' glans. ' The 

 8 corpus caver nosum' forms in 

 Man more than two-thirds of 

 the bulk of the penis: it is a 

 lengthened subdepressed cy- 

 linder, with a median groove 

 both above and below; the upper 

 groove lodging the dorsal vein, 

 arteries, and nerves, and the 

 under one the corpus spongio- 

 sum. Anteriorly the corpus 

 cavernosum terminates in an ob- 

 long and rounded extremity, 

 which is received into a depres- 

 sion on the posterior surface of the glans ; posteriorly it is at- 

 tached to the ischiopubic rami by its two crura ; and above it
