imes one of the exciting factors in production ofepithelioma of this part which, from the fact that it usually occurs in chimney-sweeps, is -called soot wart or chimne3-sweeps cancer. These furrows alsofavor retention of moisture, hence the liability of the scrotum to eczema and othercutaneous lesions. It is very elastic and permits of great distention, as is seenin large scrotal hernia, tumors of the testicle, and h3Tlrocele. Along the median line of the scrotum is the median raphe—a dark ridge, con-tinuous with the median raphe of the perineum, which shows the line of union ofthe two halves of the scrotum. When the scrotum is distended, the superficialveins are rendered prominent, and should be avoided when tapping a hydrocele. Dissection.—The integument of the penis and scrotum is reflected aftermaking two incisions, one along the dorsum of the penis and the other along theunder surface of that organ and along the raphe of the scrotum as far as the PLATE CCCXl, Tunica vasculosa

The dartos is the superficial fascia of the scrotum and penis. It contains nofat, and is a reddish-looking, thin, fascial layer, containing yellow elastic tissue andbundles of unstriped muscle fibers. Its superficial portion is elastic areolar tissue,and its deep portion is more membranous in character. It is continuous with thesuperficial fascia of the abdomen and perineum. In the scrotum the muscle fibersgenerally run at right angles to the scrotal wrinkles which they cause. The dartossends a median partition into the scrotum between the two testicles, which formsan incomplete scrotal septum. The External Spermatic Fascia is the fascia immediately beneath the dartos.It is the continuation of the intercolumnar fascia of the external abdominal ring,carried downward over the testicle and spermatic cord
