THE following is a continuation of the reports which have already appeared in the BRITISH MEDICAL JOURNAL (October 25th, 890o; May 28tl, I892; and Janualry 27th, i894). Again our standard of perfection is the absence of bacteria fromii the skin of the patient, from the hands of the surgeon and of his assistalits, from everything which came in contact with the wound, and, finally, from the wound itself. The test adopted is a simple one. A scrap of skin, towel, sponge, and so forth is cut off and
more » ... orth is cut off and dropped into nutrient broth, which is afterwards kept at a temperature of eitlher 200 C. or 360 C.; and a final opinion was not arrived at until the higher temperature had been used. If the broth reinained clear at the end of a fortnight, it was assumed that what had been put into it was sterile. In the last report some experiments were cited to show that the minute quantity of the chemical which was always conveyed into the broth with the material did not inar the result. These experiments have been continued. A number of the broth tubes which had remained clear after skin, towel, sponge, and so forth had been put into them, were inoculated witlh bacteria. An abundant and rapid growth always took place, thus proving that the amount of chemical conveyed into the broth upon the material was quite innocuous.]
