which it may be distmc, % N .^ .^ .i^y when enlarged. It is about the size 



of a horse chestnut and somewhat conical in shape, and presents for examination 

 a base, an apex, an anterior, a posterior, and two lateral surfaces. 



The base (basis prostatae) is directed upward, and is applied to the under 

 surface of the bladder. The greater part of this surface is directly continuous 

 with the bladder wall; the urethra penetrates it nearer to its anterior than to its 

 posterior border. 



The apex (apex prostatae) is directed downward and rests upon the deep layer 

 of the triangular ligament. The apex is fixed, except for the slight mobility of 

 the triangular ligament; the rest of the gland is somewhat movable. 



Surfaces. The posterior surface (fades posterior) is flattened from side to side 

 and convex from above downward; it rests on the rectum, and is distant about 

 an inch and a half from the anus. Near its upper border there is a depression 

 through which the two common ejaculatory ducts enter the prostate. This de- 

 pression serves to divide the posterior surface into a lower larger and upper smaller 

 part. The upper smaller part constitutes the so-called "middle lobe" of the pros-* 

 tate and intervenes between the ejaculatory ducts and the urethra; it varies greatly
