Only a few instruments, for instance cystoscopes and other electricalapparatus, further hard rubber instruments cannot be boiled, but theycan be safely sterilized, if they are kept in closed glass receptacles, onthe bottom of which stands a layer of pure formalin. The ascendingformalin vapors suffice completely for the sterilization of these instru-ments (Menge, Stoeckel). The sterilization of the dressing material is done best by live steamto which the material is exposed for one hour. The apparatus of Lauten- £™Q-.

Instruments can be boiled, and dress-ing material sterilized at the same time (see Fig. 28). Small glass tubescontaining a metallic alloy melting at about 105° C. (221° F.) serve forthe control of the really resulting heat of 100° C. (212° F.) (Sticher). They are placed between the dressing material, and when examinedafter the sterilization should be found melted if the heat has beensufficient. Various methods are used for sterilizing suture material; silk, silk- 42 DISEASES OF WOMEN wormgut, linen thread, silver and bronze wire are boiled with the in-struments before being used. Many methods have been recommended for the sterilization ofcatgut. Unless they kill anthrax-spores, they are useless. The cumol catgut after Kroenig, which is distributed by the f
