TO CLEAN INSTRUMENTS.

First of all, the knives, scissors, and needles should be laid carefully aside and cleaned at once. Scrub all instruments in cold water to remove blood and pus, then in hot water with plenty of soap. Rinse thoroughly in hot water, then place in boiling water, take them out singly and dry; do not drain. Following pus cases all instruments must be boiled for at least fifteen minutes in 1 per cent. soda solution.
