Morton recommends making fresh solutions foreach case, because of the fact that cocaine solutions deteriorate and losetheir anaesthetic property in a large measure in a few days. CATAPHORESIS. 241 Fig. Apparatus.—The apparatus necessary for j^roducing electrococaineausestliesia are a suitable primary galvanic battery ; preferably a dry-celichloride of silver, or a dry-cell Leclanche battery, having an electro-motive force of from ten to thirty-five volts; a reliable rheostat or con-troller so arranged that the currentmay be increased or diminished byslow gradations at the will of the oiDcr-ator; a milliamperemeter graduatedto register the twentieth part of amilliampere 5 conducting cords andelectrodes. The secondary or storage batteryis sometimes employed for producingcataphoresis. When this form of bat-tery is used the plates should besmall,—three by three inches. Thepotential of a cell of this size willbe about two volts, and the normalstrength of current at eight hoursdischarge is five-eighths of an ampere. The Edison one-hundred-and-ten-volt street current may also be em-ployed by suitably reducing thestrength of the current. The objec-tions which have been raised to theuse
