In March, 1905, the Health Department of New York City appointed a commission for the investigation of cerebrospinal meningitis, and the work of the bacteriologists, Drs. Elser and Huntoon, of Cornell University Medical College, has been continued until this time, now being reported in a lengthy monograph.1 This exhaustive, careful piece of research will unquestionably find a place among the most important studies on meningitis yet recorded. The authors have studied bacteriologically 210 cases of epidemic meningitis, and have made extensive investigations of the biology of the causal organism, its differentiation from allied cocci, the serum reactions of man and laboratory animals, the pathogenicity of the meningococcus for lower animals, its viability, and the mode of transmission and invasion of man in epidemics.

Perhaps one of the most striking conclusions reached by the authors is the essential importance of meningococcus carriers in the transmission of epidemic meningitis. As shown
