A summary of all these cases shows that there were forty -seven operations with twenty -three deaths, a rather high mortality.el. That there are cases of spontaneous recovery from malaria is an undoubted fact. One has known of numbers of cases of persons at Cedros and Chag- uanas, who with typical mild malarial attacks have taken no drugs whatever and have yet recovered in a couple of weeks. Probably in such cases the para- sites run a natural course, and the process of ex- tinction is helped by the phagocytic action of the leucocytes as well as the endothelial cells of the spleen. The writer, on two occasions, in fresh blood preparations under the microscope, saw the process of pha`ocytosis. The leucocyte (mononuclear) was near a free spherical form of parasite, and gradually by throwing out pseudopodia, envelóped the parasite and its included pigment. Hence, pigment- ed leucocytes are always found in the blood after a time in all cases of malaria.
