Instruments which fall upon the floor should not be again used until
thoroughly disinfected.
The clothing of the patient, in the vicinity of the part to be
operated upon, and the blanket and sheets used there to keep him warm,
should be covered with dry sublimate towels. All dressings should be
kept safe from infection by being stored in glass jars, or wrapped in
dry sublimate towels.

INFLUENCE OF REPOSE ON THE RETINA.
Some interesting researches have lately been published in an Italian
journal concerning the influence of repose on the sensitiveness of the
retina (a nervous network of the eye) to light and color. The
researches in question--those of Bassevi--appear to corroborate
investigations which were made some years ago by other observers. In
the course of the investigations the subject experimented upon was
made to remain in a dark room for a period varying in extent from
fifteen to twenty minutes. The room was darkened, it is noted, by
means of heavy curtains, through which the light could not penetrate.
After the eyes of the subject had thus been rested in the darkness, it
was noted that the sensitiveness of his sight had been increased
threefold.
