This interesting but highly technical book represents a summary of a series of lectures on the "immunity reactions" delivered at the University of California in the summer of 1904. The character of the subjects discussed may be appreciated by citing the following chapter subheads: Reversibility of Reactions Between Antibodies. Velocity of Reactions. Homogeneous Systems. Velocity of Reaction. Heterogeneous Systems. Equilibria in Absorption Processes. Neutralization of the Hemolytic Properties of Bases and of Lysins of Bacterial Origin. Neutralization of Diphtheria Toxin, Ricin, Saponin and Snake Venoms. The Compound Hemolysins, and the Precipitins and Their Antibodies.
Without question scientific medicine is to be congratulated on the entrance of one of the world's greatest students of physico-chemical processes, into the obscure field of the chemistry of the immunity reactions, and that Arrhenius has entered into this subject with a great deal of seriousness is evident from the scope of the undertaking, and the
