Experiments have shown that the solution of bichloride of mercury, fre-quently employed in surgical work, does not manifest its germicidal powersunder all conditions.

The inefficiency of bichloride ofmercury as a cutaneous germicide can be tested for practical purposes by im-mersing the hands for ten minutes in a 1-500 aqueous solution, and then in asterilized ammonium sulphide solution to precipitate the mercury. After this,by scraping the epithelium, cultures can usually be obtained which will grow inordinary media. If dishes and porcelain ware are to be efficiently sterilized by this means,they must be kept in a strong solution of corrosive sublimate (1-500) for fif-teen minutes after they have been thoroughly scrubbed with soap and water; thesublimate kills most of the bacteria and renders the rest inactive. Decidedly. Fig. 3.—Instrument Sterilizer. the best way to sterilize dishes is to put them into the large steam sterilizeralong with the operating suits, towels, sheets, and gauze, and subject them tothe same process of sterilization. In the experiments on skin disinfection we have to consider a factor whichwe do not encounter in the sterilization of the dishes. The albuminate of mer-cury which is formed in the tissues, when brought in contact with corrosivesublimate solutions, may incapsulate the organisms, and so render them in- 8 SEPSIS, ASEPSIS, AND ANTISEPSIS IN HOSPITALS. capable of growth. When dishes, on the other hand, are submerged in the dis-infectant solution, the organisms are at once brought in contact with thebichloride of mercury without the formation of this albuminate, and the sterili-zation is more effective. The use of chemical solutions, such as carbolic acid and corrosive sublimate,for disinfection of wounds is objectionable, because their value de
