Gives a brief outline of the history of the classification of bacteria, presenting in tabular 
form the various schemes proposed, as follows: Cohn in 1875, Winter in 1881, Van TieHiem 
Vin 1 , 884, 1 1 886 ’ Hue PT >H 111 1886 and later, Zopf in 1885, De Toni in 1889, Miqueliu 
K 91 and \Y oodhead in 1891. Kach ot these is briefly discussed. Suggests in conclusion 
that in the tuture notes be made on habitat, nutrient medium, gaseous environment, tem¬ 
perature, morphology and life history, special behavior, and pathogenic effects. («T. F. J.)

Describes apparatus for experiment and gives details of the results. The species experi¬ 
mented with were Monilia Candida , Oidium albicans, and Saccharomyces mycoderma. The 
results showed more rapid growth in the agitated than in the stationary flask, but a greater 
amount ot alcohol was found in the latter than the former. The increase in growth in the 
agitated flask is apparently due to more perfect aeration and better nutrition. (J. F. J.)
