THE SIXTH ANNUAL MEETING OF THE SO- 

 CIETY OF AMERICAN BACTERIOLOGISTS. 



The sixth annual meeting of the Society 

 of American Bacteriologists was held at 

 the Laboratory of Hygiene, University of 

 Pennsylvania, Philadelphia, Pa., on De- 

 cember 27 and 28, 1904. 



The opening address was by President 

 F. G. Novy, of the University of Michigan, 

 on 'The Hematozoa of Birds.' 



On the Hematozoa of Birds: F. G. NovY, 



University of Michigan. 



An abstract or partial summary of the 

 results obtained in this study appeared in 

 American Medicine, November 26, 1904. 

 The work in full will come out in two 

 papers, the first of which, dealing with the 

 Trypanosomes in birds, will appear in the 

 second number (1905) of the Journal of 

 Infectious Diseases; the second paper, deal- 

 ing with the Cytozoa, may be expected in 

 the third number of that journal. 



The Effect of Freezing on Bacteria: Erwin 

 F. Smith and Deane B. Swingle, U. S. 

 Department of Agriculture. 

 More than 100 freezings were made 

 using about a dozen different bacteria — 

 saprophytes and plant and animal patho- 

 genic forms. Quantitative determinations 

 were made in all cases. With the excep- 

 tion of Bacillus radicicola, all of the ex- 

 posures were made in -|-15 peptonized 

 beef bouillon, using cultures 24 to 48 hours 

 old. Part of the freezings were made in 

 liquid air, the time of exposure varying 

 from 10 minutes to 24 hours, but usually 

 one half hour. The rest were made in salt
