a Male and a Female Dromedary. 13 



VesiculcB seminales wanting. 



Membranous portion of the urethra six and one-fourth 

 inches long ; transversely, on the inner surface, one inch at 

 neck of bladder, one and seven-eighths inches at verumon- 

 tanum and five lines only at the commencement of the 

 penis. Yerumontanum two and one-quarter inches from the 

 neck of the bladder and not very prominent ; numerous 

 fine, dense rugae diverged ofi" from it, amongst which were con- 

 cealed the openings of ducts ; there were, also, longitudinal 

 rugae, more marked and extending off from it along the me- 

 dian line anteriorly and posteriorly. Spongy tissue external 

 to the mucous coat, and about one line thick. Muscular coat 

 very strongly developed, measuring one-half an inch at the 

 thickest part ; the fibres were transverse and met upon that 

 surface of the canal which was towards the rectum, in a thick 

 mass of condensed cellular membrane or tendon about three- 

 fourths of an inch wide. 



The Prostate gland consisted of a single, broad, thick, and 

 very regular lobe, of a somewhat triangular form, the apex 

 being directed towards the urethra, measuring two and three- 

 fourths inches transversely, and two inches in the opposite 

 direction. The texture was close, whitish and homoge- 

 neous ; filled with an opaque, creamy fluid, the ducts termi- 

 nating in many openings on each side of the verumontanum. 

 According to Cuvier, (Anat. Comp., 1st ed.. Vol. V., pp. 43 

 and 47,) this gland in the ruminants is always double, and has 

 but a single excretory duct ; he also remarks on the large size 

 of the central cavity in the camel. 



Cowpers glands, situated just behind the bulbo-cavernosus 

 muscle, were remarkably distinct. They were of a very reg- 

 ular, oval form, one inch long and one-half an inch at the 

 widest part, of a light red color, slightly granular in structure, 

 and directed obliquely forwards towairds the median line. 

 The ducts were large, filled with a starchy secretion, and 

 terminated at the bottom of a cul-de-sac, which was five 

 lines in depth and formed by the inner membrane of the 

 urethra. Each of these glands, separately, was surrounded 

 by a strongly developed expulsor muscle, which was from
