822. Therapeutic Uses

Limon. f3ij., Aquae fviij., M. Dose for a child, gutt. x. - xij. every six or eight hours. The solution should be fresh. A diluted solution also forms an excellent gargle for the sore throat which accompanies this disease.

823. As a preventive to the infection of Puerperal Fever, its efficacy has been established by Dr. Semelweiss,** of Vienna. At one period a large number of cases of Puerperal Fever occurred in Vienna, and they were supposed to arise from the want of proper precautions in the surgeons and students engaged in postmortem examinations of puerperal subjects. Dr. Semelweiss therefore insisted on the necessity of their washing their hands in a solution of Chlorine, prior to and after every such postmortem; and the result was, that the rate of mortality was reduced from 30 to 7 per month, which was about the ordinary average. It is a precaution which should never be neglected.
