![solution, these emulsions having been made and counted by us, in one instance by both the living and blood methods, in the other by the blood method only, with fairly uniform results. The figures are as follows:— 1.—Agar Emulsion “A ” of September ZOth. Counts, made at Royal Army Medical College :— A. Living Method (by dilution) .. .. 32,000 millions per c.c. B. Blood Method (by red B.C.):— I. by A.B.S., 26,240 millions \ 30 390 IT. „ W.B.L., 34,540 1 Weight Correlation, made at Lister Institute by Dr. Martin:— I.

Translating this figure into germs from the correlation obtained with agar emulsion “ A ” gives 10,300 millions per c.c., or within 8°/o of the value obtained by taking the average of three independent counts by different workers using Dr. Wright’s blood method— viz.: 9,596 millions per c.c. Working on the assumption that the correlation obtained from these agar emulsions was accurate. Dr. Martin further dried and weighed for me three samples of broth vaccines which 1 will call “A,” B and “ C,” made and sterilised under identical conditions, with the following results:— “ A.”—Unlgsolized.
