    These might be seen without dissection lying upon the surface of the bladder, just above the attachment of the rectovesical fascia, and receiving the veins from the wall of the bladder. Larger veins were placed more deeply in the angle between the prostate and the bladder, and these appeared to be the direct continuation of the sinuses of the prostatic plexus. Veins passed upwards into those from the lobes of the prostate, but the greater number of these prostatic veins appeared to pass out to join the plexus at the point of junction of the posterior and lateral surfaces and the Fig. 8. —Prostatic plexus of veins, side view.

Towards the posterior part of the prostate these plexuses came into relation with the end of the seminal vesicles, the vasa deferentia, and the lower ends of the ureters, and received veins surrounding these structures (fig- §)• Some variations were found in different subjects. Sometimes the vertical stem of the Y was short, and the arms began to spread outwards before reaching the base of the prostate. The veins were thus spread out over a greater surface of the front of the prostate. The prostate varies a good deal in size within normal limits, and it is in the longer prostates that the arrangement described is best seen. In small, short, poorly developed glands the vertical portion of the plexus is much shortened. It will be seen, therefore, that the prostatic plexus comes into relation
