    anatomy of the prostate. I shall only take np certain points which appear to me important surgically. The Sheath. The prostate is surrounded by a layer of fascia which envelops it except at its basal attachment to the bladder. At the apex of the gland this sheath blends with the muscular tissue surrounding the urethra. Sir J Fig. 1.—Undissected prostate and surrounding tissues removed from body. Anterior surface. A, Part of anterior surface of prostate between reflected lateral layers of sheath. B, Anterior wall of bladder. C, Rectovesical fascia on upper surface of levator ani muscle.

G, Apex of prostate showing termination of dorsal vein of penis. H, Striped muscle surrounding urethra. J, Urethra. K, Levator ani muscle. Henry Thompson described this fascial envelope as the “ sheath ” in his work on the prostate, and although the term has not been widely adopted by anatomical writers, I have used it here, as it clearly distinguishes this layer of fascia from the tissue immediately surrounding the prostate gland which Thompson called the capsule. This sheath is derived from the rectovesical layer of pelvic fascia. The rectovesical layer of pelvic fascia passes inwards from the side wall of the pelvis on the upper surface of the levator ani muscle, and meets the
