If the patient is at a hospital the instruments needed,except the knife, will be found on the examining trayand should be freshly sterilized. The knife (myringo-tome) should be placed in 95 per cent, alcohol and theblade should never be wrapped in cotton, but should betreated with the same care as a cataract knife.
