    « of the life cycle of the plasmodium, fascinating and original though they may be.” While the great question of malarial fever is one of widespread interest, it is the one phase of it that the writer is investigating, viz.: The waterborne means of infection. Laveran says:1 “Numerous facts tend to prove that the infection may take place through drinking water, and that persons who have contracted paludism (malarial fever) have almost always made use of water of palustral (with humid or marshy soil) localities.” He says further: 1. “It has been found repeatedly that in the same localities, among persons living under the same con- ditions, but drinking water from different sources, some were attacked by palustral fever while others escaped. 2. “In certain localities which were formerly in- salubrious it has been sufficient to place pure water at the disposal of the inhabitants, instead of the stagnant water which was formerly used, for palus- tral fevers to disappear. 3. “In some localities, otherwise very healthy, peo- ple may contract fever, whose drinking water comes from unhealthy localities, and the persons most ex- posed to infection in these conditions are those who consumed most water, 4. “Travelers passing through unhealthy countries often succeeded in escaping fevers, by only drinking water that has been boiled, while people who do not take that precaution suffer severely.” Dr. Norbury2 in the Medical Record of Oct. 6, 1894, says on the subject of “Malaria a Waterborne Dis- ease:” “I wish to add my experience and observa- tion to the line of inquiry pursued by Dr. W. H. Daly, of Pittsburg, Pa., in his most excellent paper in the Medical Record of Sept. 15, 1894, regarding malarial infection. In the summer of 1881, while employed under the directions of Maj. G. J. Ly- decker, U. S. A., in the construction of the Kamps- ■ Paludism. By A. Laveran. New Sydenham Society, published 1898.
