' I cannot let pass this opportunity of pointing out an evolutional parallel in the history of phagocytes which tends to harmonize to some extent the views of those who insist on the bactericidal and the anti-toxic properties of serum, with Metschnikoff's view that the phagocytes are of prime importance. In the recent debate at the Pathological Society of London, it was pointed out by several speakers that even if it be admitted that the serum and exudations have, in relation to certain special cases, these properties or rather contain substances having these properties--those substances must be derived from the living cells of the organism, and probably from leucocytes. The parallel to which I refer is that of intra-cellular and cavitary digestion. The alimentary canal of some lower animals is lined by phago.

cytes, which individually ingulf solid particles of food, and digest them by means of ferments, acids, &c., formed within the phagocytes. A later stage of evolution of the digestive system consists in the discharge by these cells of the food-dissolving substances elaborated by them into the common liquid occupying the cavity which they surround. The food dissolving substances are no longer found exclusively in the cells, but in the liquid which bathes them. Yet no one ascribes a special power to the gastric juice, or hesitates to trace its qualities to the transformed intra-cellularly-digesting cells. So with bactericidal and anti-toxic juices: they must be traced (when their existence is proved) to the modification of the modus operandi of intracellularly-digesting phagocytes.
