    The wliole of the mechanical detail has been carefully worked out for me by Messrs. Blaise and Co., St. James’s Street, S.W. PERINEAL SECTION PROBE-POINTED CANNULA. In’ the operation of external urethrotomy, and of perineal section, most surgeons are desirous of ascer- taining the nature and size of the urethra posterior to the stricture; in the operation of opening an empty bladder per rectum (which I have twice performed in the Westminster Hospital for perineal fistulas), the catheter must be introduced; and for these three operations the probe-pointed cannula is a most valuable adjunct. The uppermost diagram illustrates at a glance the instrument. The slot running along the central length of the instrument is for the easy introduction and re- moval of a retentive catheter.
