work." This was not the first of Dr. Sternberg's works in bac- 

 teriological research. It was preceded by a work on Bacteria, of 

 498 pages, inclnding 152 pages translated from the work of Dr. 

 Antoine Magnin (1884); Malaria and Malarial Diseases, and Pho- 

 tomicrographs and How to make Them. The manual is at once a 

 book for reference, a text-book for students, and a handbook for 

 the laboratory. Its four parts include brief notices of the history 

 of the subject, classification, morphology, and an account of meth- 

 ods and practical laboratory work — "all clear and concise"; the 

 biology and chemistry of bacteria, disinfection, and antiseptics; a 

 detailed account of pathogenic bacteria, their modes of action, the 

 way they may gain access to the system, susceptibility and immu- 

 nity, to which Dr. Sternberg's own contributions have been not 

 the least important; and saprophytic bacteria in water, in the soil, 

 in or on the human body, and in food, the whole number of sapro- 

 phytes described being three hundred and thirty-one. " The merit 

 of a work of this kind," Nature says, " depends not less on the 

 number of species described than on the clearness and accuracy of 

 the descriptions, and Dr. Sternberg has spared no pains to make 

 these as complete as possible." The bibliography in this work 

 fills more than a hundred pages, and contains 2,582 references. 

 A later book on a kindred subject is Immunity, Protective Inocu- 

 lations, and Serum Therapy (1895). Dr. Sternberg has also pub- 

 lished a Text-Book of Bacteriology. 



Bearing upon yellow fever are the Report upon the Preven- 

 tion of Yellow Fever by Inoculation, submitted in March, 1888; 

 Report upon the Prevention of Yellow Fever, illustrated by photo- 

 micrographs and cuts, 1890; and Examination of the Blood in Yel- 

 low Fever (experiments upon animals, etc.), in the Preliminary 

 Report of the Havana Yellow-Fever Commission, 1879. Other 

 publications in the list of one hundred and thirty-one titles of Dr. 

 Sternberg's works, and mostly consisting of shorter articles, relate 

 to Disinfectants and their Value, the Etiology of Malarial Fevers, 

 Septicaemia, the Germicide Value of Therapeutic Agents, the Eti- 

 ology of Croupous Pneumonia, the Bacillus of Typhoid Fever, the 

 Thermal Death Point of Pathogenic Organisms, the Practical Re- 

 sults of Bacteriological Researches, the Cholera Spirillum, Disin- 

 fection at Quarantine Stations, the Infectious Agent of Smallpox, 

 official reports as Surgeon General of the United States Army, ad- 

 dresses and reports at the meetings of the American Public Health 

 Association, and an address to the members of the Pan-American 

 Congress. One paper is recorded quite outside of the domain of 

 microbes and fevers, to show what the author might have done if 

 he had allowed his attention to be diverted from his special absorb-
