To the Surgeon Ganeral,
I beg to report that a number of tests of the germicidal value of the speciments of Red Cross soap and sublimate soap (Schieffelin & Co.), have been made with the following results:
A solution of Red Cross soap made by dissolving 3/8 of a cake in one litre of sterilized water destroys staphylococcus pyogenes aureus in two minutes. A solution of the sublimate soap prepared in the same proportion does not destroy aureus in 45 minutes. I believe that the first named soap possesses decided germicidal properties.
Surgeon, U.S. Army,
