Compact apparatus for sterilization is supplied by every surgical instrument maker. The instruments are usually placed on a wire gauze tray with handles and then into the sterilizing dish, so that when the boiling is completed, they are lifted out on this tray by means of hooks supplied for the purpose. They are at once transferred to the shallow dish containing the 1 in 40 Carbolic Acid solution detailed above. By these means the instruments are cooled ready for use, for obviously they cannot be taken directly out of the boiling water with the fingers; and the fact that they are in an antiseptic solution, prevents the access of any germs during the short interval before they are actually handled. The _dressings_ used in Circumcision should consist only of _lint_ and _gauze_. It is necessary that the dressing should be sterilized and also impregnated with some antiseptic so as to render harmless any infective material which may accidentally contaminate the wound after circumcision. These dressings are supplied by manufacturers, already sterilized by exposure to super-heated steam, and rendered antiseptic by various chemical agents. Carbolic Acid used for the hands and the instruments, is often employed for the dressings, the antiseptic being fixed in the lint and the gauze by a special process. Most surgeons, however, prefer “_double cyanide_” dressings, in which the antiseptic used is a salt known as cyanide of zinc and mercury. From the first dressing until the circumcision is absolutely healed nothing but gauze need be used. In a normal case no other application of any kind whatsoever is required. It is usual however in applying the first dressing at the circumcision to use lint to surround the root of the penis as it is firmer than gauze. When this is done a piece of tape is twisted round the lint to retain it in position. The tape and the lint must both be sterilized like the gauze. The best course to adopt in regard to the dressings is to obtain them from a reliable firm of manufacturers, who will supply them ready cut to the pattern required, packed in small sealed aseptic tin cases ready for use.
