Rh is a matter of as great importance in chronic as in acute disease, hence any agent which diminishes the efficiency of these organs in ridding the system of poisons, either those normally and regularly produced, or those of an accidental or unusual character, must be pernicious and dangerous in use."

Among the more recent findings of science in regard to the effects of alcohol are the action of this drug upon the leucocytes or "guardian cells" of the body. Leucocytes are defined to be "minute, nucleated, colorless masses of protoplasm, capable of ameboid movements, found swimming freely in blood and lymph, in the reticulum of lymphatic glands, and in bone-marrow and other connective tissue." The white corpuscles of the blood are leucocytes. "The work of these cells is to prey upon and take into their substance bacteria and other micro-organisms within the blood and tissues. This destruction of bacteria, and other noxious organisms, has the biological name of phagocytosis."

Dr. Alonzo Brown in Physician and Surgeon says of phagocytosis:—

"Recently a brilliant theory has been projected into the histological world. It is the principle of phagocytosis. The beauty of it is so great that we are attracted by it, and its reasonings have riveted general attention. It is said that certain cells have the power to absorb and so destroy other cells. This is phagocytosis. It is said that 'the cells which are known to possess phagocytocic properties are the leucocytes, mucous corpuscles, connective tissue cells, endothelia of blood vessels and lymphatic vessels, alveolar eypithelium of
