The scrotum is rich in sebaceous glunds, and the tunica vagimdis is separated by a serous layer from the peritoneal cavity. 'Jesticles.—Tliese are ovoid, and situated in an oblique direction downwards and inwards ; their largest curvature is forwards. The epididymis oti'ers the same arrangement as already noticed, except that the vns deferens, in being detached from the globus minur, is bent .omewhat suddenly to reach the abdominal cavity. There are several diverticuli annexed to the epididymis, named the pediculated hydatid of Morgagni, non-jediculated hydatid uherrant vessels, anl roipus innominatum of Giraldes. Fie;.

The hydatid of Morgagni is a little projection at the head of the epididymis, filled with a serous fluid which is never mixed with tlie semen. The non-pedicuhited hydatid is a small white mass which rises from tlie testicle Ht some distance from t
