BY HERBERT FRENCH, M.B., E.Ch.Oxon., Late Gillson Research Scholar, Apothecaries' Society. ITHOUT entering into great detail upon the reasons for experiments of this nature, a few words of introduction seem necessary. The functions of the leucocytes of the blood in health are even yet but imperfectly understood, but one of them is held to be that of protecting, or helping to protect, the body from certain infections, particularly those due to micro-organisms. In some cases the microbial attack is local, and the leucocytes seem able to engulf or devour the bacteria, the process being termed phagocytosis; Metschnikoff is the strong champion of this view of leucocytic function. In other cases the infection is general throughout the body, though the microbes themselves may still be local. For example, in pneumonia, where the pneumococci seem confined to the lungs, and yet the whole system is affected by the poisons they produce. In yet other cases the microbes themselves are disseminated everywhere, as in cases of septicaemia; and in other cases, such as scarlet fever, the body is poisoned in some way, though no microbes have been found. Probably the nature of the process of
