A study of the antigenic potency of influenza virus inactivated by ultraviolet radiation has been made. Virus so inactivated is still capable of functioning as an immunizing agent when given to mice by the intraperitoneal route. In high concentrations inactivated virus appears to be nearly as effective as active virus but when quantitative comparisons of the immunity induced by different dilutions are made, it is seen that a hundredfold loss in immunizing capacity occurs during inactivation.

Chemical extraction of lyophilized and ground staphylococci of type A has yielded a type-specific, antigenic fraction which has been shown to be protein. In precipitin tests this fraction reacts in high dilution with homologous immune sera prepared by the injection of animals either with the whole organisms or with the protein itself. Reactions with sera prepared against heterologous types of staphylococci occur only in low dilutions.

The action of NaCl upon the effect of MgCl(2) upon oxalate buffer systems, interpreted by Simms as an instance of antagonism of Na(+) and Mg(++), has been shown to be capable of formulation as the effect of increasing ionic strength upon the dissociation of MgC(2)O(4) into magnesium and oxalate ions.
