Preparatory and after treatment in operative cases . ito-urinary cases. The appa-ratus sterilizes the water abso-lutely and is constructed to with-stand pressure of 50 pounds to thesquare inch. To fill, the water ispoured into the funnel and thequantity noted on the water burner beneath is then lightedand the water heated until steam issues from the funnel, when the valve is screwed down. Suffi-cient steam pressure will then be generated to blow off safety valvewhich is set at 15 pounds or 250° F. This temperature is main-tained for fifteen to twenty minutes for absolute sterilization. Thecapacity of the apparatus should be about two gallons. Fig. 64 shows an apparatus similar to Fig. 63, except that thewater is not subjected to pressure. If the contents be heated toboiling for twenty minutes, the water is practically sterile, butthis apparatus is not so certain in its results as the former (). The objection to the steam pressure sterilizer (Fig. 63) isthat the water is liable to be either too hot or too cold when about.

This is obviated in the apparatus shown in Fig. 65by a coil within the tank, which may be connected with the coldwater tap. In this way the temperature of the water may bemodified, its range being indicated by a thermometer affixed to the apparatus. This apparatus is de-vised for office use and answers thepurpose very well. Neither of these apparatuses per-mits sufficient elasticity with respect tothe adjustment of the temperature ofwater, which is essential to the bestpossible work. The contingencies metin operative work are well met by theapparatus shown in Figs. 65 and 66. The hydrant water supply is di-rectly connected to filter M at point filter itself consists of a naturalporous stone bougie which can be takenout of the metal mantle for purpose ofcleaning and be placed ba
