'Mast and Pace ( '33, et seq.) designate all their culture solutions acetate-ammonium solutions, but the amount of sodium acetate in them varied, for some contained 150 mg. CH,COONa and others 150 mg. CH,COONa. 3 H,O. The solution described in table 1 contains 249 mg. of CH,COONa. 3 H,O which is equivalent to 150 mg. of CH,COONa.

S. 0. M A S T AND D. Rf. PACE assert that "addition of a small amount of II,SiO, notablT augments the yield of cultures of Bacille tuberculeux." Pace ('32) found that the rate of growth in Amoeba proteus increases greatly if sodium silicate is added to the cultures, and Mast and Pace ('33) found the
Hydrogen peroxide in oxygenated Ringer's solution increases the steady E.N.F. of frog skin from a just detectable amount at 1.5 x 10-6M peroxide to a maximum at,8 X lo-\* 31 (Marsh and Carlson, '41). Higher concentrations reversibly depress the steady potential difference below the control level. T
