8 MANUAL OF BACTERIOLOGY. 



consulting the large text-books and weekly medical journals, 

 obtain much assistance from technical periodicals. The 

 Journal oj Experimental Medicine, Journal of Medical Research, 

 and the Journal of Infectious Diseases, published in this country, 

 and the English Journal of Pathology and Bacteriology and 

 Journal oj Hygiene devote much valuable space to the 

 subject. 



The Journal of Tropical Medicine also contains contribu- 

 tions. 



A reading knowledge of German and French is very desirable. 

 The Centralblatt fur Bakteriologie, etc., a German periodical, 

 and the Bulletin de VInstitut Pasteur, published semimonthly 

 in Paris, contain abstracts of most of the important researches 

 made in all parts of the world. The Annales de Vlnstitut 

 Pasteur, the Zeitschrijt fur Hygiene, the Archiv fur Hygiene 

 and the Hygienische Rundschau contain many original arti- 

 cles on bacteriological subjects. 



The whole literature of any specified subject in bacteriology 

 can be most conveniently found in Baumgarten 's Jahresbericht 

 der Mikroorganismenlehre. 



Those who are interested in agricultural bacteriology should read the ex- 

 periment station records and the various bulletins issued by the Department 

 of Agriculture of the United States. They can usually be obtained upon appli- 

 cation to the Department at Washington, D. C. The bacteria that produce 

 disease in domestic animals are described in Dr. V. A. Moore's book, "The 

 Infectious Diseases of Animals," Taylor & Carpenter, Ithaca, N. Y., 1906, and 

 in the "Special Report on the Diseases of Cattle," United States Department of 

 Agriculture, 1904; also Diseases of the Horse, Department of Agriculture, 1907 



Historical Sketch. Nearly all that we know of bacteria 

 and the part they play in producing disease has been learned 

 during the last half of the last century. Nevertheless, many 

 facts were known long ago, and even by the ancients, which 

 were effective in directing the thought of later years. The 

 epidemic nature of certain maladies was naturally among 

 the earliest of these to be noticed, and was, even until com-
