The universal instruments of Bransford Lewis and Tilden Brownpossess features of great practical utility. Sterilization of Cystoscopes and Ureteral Catheters.—In order to sterilizethe cystoscope before using, place it for five minutes in a solution of mercuryoxycyanid (i: 1000) or formaldehyd (i: 500). The steriUzing power of formalde-hyd gas is not to be relied on. Some operators use a 5 per cent, solution ofphenol, in which the instrument is immersed for twenty-four horns, after whichit is dipped into glycerin, which both neutralizes the phenol and lubricates the.

Should formaldehyd solution or formahn gas be used, always washthe instrument thoroughly with salt solution before using to prevent irritationby the sterilizing medium. Dr. M. P. Willard, of San Francisco, in Jour. Amer. Med. Assoc, Octo-ber 4, 1913, advocates the following method for sterilizing ureteral catheters:The ureteral catheter is placed in a muslin bag 2 cm. wide by 75 cm. long. Thebag is enclosed, with the catheter in it, in parafl&n paper, and secured by encir-cling strips of adhesive plaster. As many may be prepared as is thought neces-sary. The package is placed for twenty minutes in an autoclave with a pres-sure of 8 to ID pounds. When the catheter is to be used the paper is rerriovedand the end of the instrument is exposed by pulling back the Hnen bag and the Technic of Cystoscopy 1303 / tip of the catheter is engaged in the carryin
