Two objections to this method occur to us: (1) Whoever has performed or witnessed supra-pubic cystotomy, either for the purposes of removal of a calculus or a neoplasm from the interior of the bladder, must have been struck by the difficulties in the way of a thorough appreciation of the condition of its posterior wall low down, or of the cystic neck. Unless specially devised instruments are available for each particular form of prostatic enlargement, it would seem to be a matter of great uncertainty as to just how much of the growth is removed. (2) Until satisfactory granulation of the wound surfaces has been accomplished, drainage, to be efficient, must be facilitated by placing the patient upon one or the other side, a position difficult to maintain, particularly in old people. RESEARCHES UPON THE VAGINAL PROCESS OF THE PERITONEUM AS A PREDISPOSING CAUSE OF TENDENCY TO EXTERNAL INGUINAL HERNIA. H. Sachs (Archiv. f. Klinisch. Chirurgie, Band xxxv., p. 321–372) advocates quite decidedly the view, basing his opinions upon preparations of the spermatic cord examined and upon microscopic examinations of cross sections of the latter, particularly as to the relations of the vas deferens and the vessels to the vaginal process of the peritoneum, that the latter is formed before the beginning of the descent of the testicle rather than as a portion of the abdominal wall formed or dragged into position by the testicle in its descent. In proof, he alleges that he has always found, in cases of incomplete descent of the testicle, that organ upon the posterior wall of the vaginal process, and not on the floor of the same. In females, the formation of the canal of Nuck cannot be said to be due to any dragging.
