indicated by a line of from 4 to 8 bubbles extending down the line of inoculation within 48 

 hours at 20°C— Of 60 food strains studied 32 were of the aerogenes type and 20 of these (or 

 62.5 per cent) were positive in adonite and the same number, 62.5 per cent, produced gas in 

 peptone gelatine. Of the 17 strains of aerogenes that were Voges-Proskauer positive, 82.3 

 per cent were adonite fermenters and S8.2 per cent gave gas in peptone gelatine. Of 37 known 

 fecal strains studied 36 were negative in adonite and 36 did not produce gas on peptone 

 gelatine." — [Author's abst. of paper read before Soc. Amer. Bact.]

 pi. 1919.] Absts. Bact. 4: 102. 1920.— "The bio-chemical portion of this monograph repre- 

 sents a contribution of the highest value to our knowledge of the physiology of a puzzling 

 bacterial complex. From a systematic standpoint it is less illuminating. The evidence for 

 combining the streptococci and the Bulgarian bacillus group in one family is suggestive, but 

 hardly conclusive; while as in previous communications Jensen appears entirely innocent of 

 any knowledge of the principles of biological nomenclature or of any respect for the work of 

 previous investigators. His genus Betacoccus is apparently Leuconostoc of van Tieghem, 

 and his Thermobacterium is certainly Lactobacillus Beijerinck; while many of his specifio 

 names are merely confusing synonyms of perfectly valid names given by previous investi- 

 gators." — D. Reddick.

 Krumwiede, Jr., L. A. Rogers, and G. H. Smith. Abstract of final report of the committee 

 on characterization and classification of bacterial types. [Abstract.] Absts. Bact. 4: 1. 1920. 

 — "As a result of criticisms of the preliminary report of the committee (Jour. Bact. 2: 505) 

 made at, and subsequent to, the 1917 meeting of the Society, the committee presented a 

 revised classification of the families and genera of the Actinomycetales and Eubacteriales, 

 38 genera being finally included, with type species for each. In addition to the classification 

 itself the committee presented an artificial key to the families and genera recognized, and a 

 generic index of the commoner species of bacteria with the names ordinarily used referred to 

 their proper genera under the proposed classification. The committee recommended that 

 the following names be adopted by the Society as approved genera: 



Acetobacter Fuhrmann Leuconostoc Van Tieghan 



Actinomyces Harz Micrococcus Cohn 



Bacillus Cohn Rhizobium Frank 



Bacterium Ehrenberg Sarcina Goodsir 



Chromobacterium Bergonzini Spirillum Ehrenberg 



Clostridium Prazmowski Staphylococcus Rosenbach 



Erythrobacillus Fortineau Streptococcus Rosenbach 



Leptoteichia Trevisan Vibrio Mueller 



and that The Committee on Characterization and Classification of Bacterial Types be dis- 

 charged and that a new committee on Bacterial Taxonomy be appointed (1) to study and report 

 to the Society from time to time in regard to problems of nomenclature, including such revi- 

 sions of the nomenclature in the present report as may seem necessary; and (2) to take the 

 proper steps to secure action at the next International Botanical Congress leading to the gen- 

 eral ends contemplated in the 1916 recommendations of the Society. — (a) That French, Eng- 

 lish and German may be substituted for Latin in the diagnosis of bacterial species, (b) That 

 the date of publication of the third edition of Zoph's Spaltpilze (1883) be considered the 

 beginning of bacterial nomenclature for the purpose of determining priority, with the excep- 

 tion of a definite list of genera conservanda. (c) That such of the approved generic names 

 specified above as may be found to require such action be recognized as genera conservanda 

 in bacterial taxonomy. — Both the recommendations of the Committee were adopted by the 

 Society." — [Abst. by C.-E. A. Winslow of report made to Soc. Amer. Bact.]
