Bacterial Therapeutics—Mortality among Medical Men—Cerebral Abscess after Empyema—Portrait of William Harvey.
The theory of the survival of the fittest, and consequently that in the struggle for existence the weakest must go to the wall, has led Dr. Cantani to apply these principles in the case of one particular germ—the bacillus tuberculosus, or that which causes consumption—to be opposed by another species of germ. His idea is that of encouraging the natural warfare of the germs already noted. The battle-field here is the human lung. The combatants are the bacillus just mentioned and a certain other germ known as the bacterium termo. Both combatants are well known in the field of microscopic inquiry, and the hoped for result of the battle is the rout of bacillus by bacterium; in other words, the clearance from the lung of the former and disease-producing germ by one which is not disease-producing, and which
