Another of these is ren- dered particularly remarkable by the fact that the gas (subcutaneous) took fire with slight detonation (as in M. Bally'scase), and burned with a bluish flame ; here the patient had died of haemorrhage after removal of a tumour from the back, and was examined six hours after death, the thermometer (Reaum.) mark- ing only + 2°. Similarly Dr. Graves has noticed emphysema of the abdominal parietes in a sufferer from frequent epistaxis. In all this there is much mystery. M. Rerolle conjectures that, in such cases, air is absorbed b}' the radicles of the pulmonary veins, — the air would then have no claim to be considered adventitious, and the hypo- thesis is, perhaps, not to be rudely rejected. ( Walter Hayle Walshe.) PROSTATE GLAND. (Corpus ghmdu- lostim ; IT(jooTar»jc, Gr. ; die Vorste/ierdntse, Germ.; La Prostate. Fr.).—The prostate is a glandular body surrounding the neck of the bladder and beginning of the urethra of the male, deriving its name from its position in front of the vesiculae seminales. It is situated in the anterior part of the pelvis, behind and below the level of'the symphysis pubis, posterior to the triangular ligament of the urethra, with which it is connected by a continuation of the latter with its capsule. It has the mem- branous part of the urethra in front of it, and somewhat below its level, and it rests upon the anterior surface of the middle of the rec- tum. The prostate is perforated by the ure- thra, two thirds of the gland are below this canal ; it inclines obliquely downwards and forwards fr
