H9 is especially seen in old subjects: it corre- sponds with the anterior extremity of the Fig. Front view of the bladder and prostate. a, bladder; b, ureters ; c, uvula vesicaj; d, prostate gland ; e, openings of prostatic ducts ; f, a probe passed into the sinus pocularis ; g, g, bristles in vasa ejaculatorium ; h, membraneous portion of urethra, trigonum vesicce, and is known by the names of the uvula vesicce, luette vesicate, valvula pylorica of Amussat. In the healthy state of the bladder and prostate, this elevation is frequently scarcely perceptible, unless the bladder is much contracted ; but it is subject to considerable increase in size, and is gene- rally involved in those cases of enlarged pros- tate which are of such frequent occurrence in the old person, and where the third lobe is the seat of hypertrophy. Mercier describes this vesico-urethral valve as a semicircular fold, raised suddenly at a right angle from the posterior surface of the neck of the bladder, and composed of a tissue somewhat resem- bling muscle ; and Mr. Guthrie, in his lectures delivered at the College of Surgeons in the year 1830, directed attention to it as fre- quently the seat of disease totally independent of any enlargement of the third lobe of the prostate ; but to this I shall again direct attention when the morbid anatomy of the prostate is under consideration. Intimate Structure. — The prostate comes under that division of the glandular system, inappropriately termed conglomerate. Miiller places it in his fourth order of glands—"g/ati- dulcc ex ccllulorum contextu spongioso componitce, med'ris ccllulis in ductus excretorios hiantibus, sine lobulorum divisione ; It is ar- ranged by Cuvier under the head of supple- mentary glands of the male organs of genera- tion. The external covering of the gland, de- rived, as already described, from the vesical fascia
