_Care of Instruments_.--The endoscopist must either personally care
for his instruments, or have an instrument nurse in his own employ,
for if they are intrusted to the general operating room routine he
will find that small parts will be lost; blades of forceps bent,
broken, or rusted; tubes dinged; drainage canals choked with blood or
secretions which have been coagulated by boiling, and electric
attachments rendered unstable or unservicable, by boiling, etc. The
tubes should be cleansed by forcing cold water through the drainage
canals with the aspirating syringe, then dried by forcing
pipe-cleaning worsted-covered wire through the light and drainage
canals. Gauze on a sponge carrier is used to clean the main canal.
Forceps stylets should be removed from their cannulae, and the
cannulae cleansed with cold water, then dried and oiled with the
pipe-cleaning material. The stylet should have any rough places
smoothed with fine emery cloth and its blades carefully inspected; the
parts are then oiled and reassembled. Nickle plating on the tubes is
apt to peel and these scales have sharp, cutting edges which may
injure the mucosa. All tubes, therefore, should be unplated. Rough
places on the tubes should be smoothed with the finest emery cloth,
or, better, on a buffing wheel. The dry cells in the battery should be
renewed about every 4 months whether used or not. Lamps, light
carriers, and cords, after cleansing, are wiped with 95 per cent
