In the estimation of the efficiency of germicides it is well established that various factors may have an important influence on the results obtained. Among these factors may be mentioned the effects due to H-ion concentration, temperature, presence of organic matter and concentration of organisms. In connection with the salts of heavy metals such as HgCl2, a source of error is to be found in the bacteriostatic action of traces of the metal Hg introduced into the subcultures with the inoculum (Chick, 1908; Shippen, 1928; Leonard, 1931).
