Omelianski finds two niorphologicall}' similar bacteria 

 capable of ferinentin.g pure cellulose (S^vedish filter pa- 

 pen in mineral solutions with chalk. Both ijrow aiuero- 

 bically, and bear spores iu a swollen terminal part. One 

 called the hydrogen ferment breaks uyt cellulose with the 

 formation of hydnj^en, carbon dioxide, acetic acid, and 

 butyric acid The otlicr, called the marsh-iias ferment, 

 breaks ii]") cellulose with the formation of maish-gas, 

 carbon dioxide, acetic acid, and butyric acid. The 

 cultures were made tiy the selective method, by wdiich 

 means most of the accompanying forms were crowded 

 out. The hydrogen ferment was isolated from the 

 methane ferment by heating tlie material used for 

 the first transfer (from the methane-yielding ferment) 

 for 15 minutes at 70", the subsequently inoculated 

 flasks then gave oiil>' the hydrogen fermentation The 

 organism rif tli.' latter was isolated pure on potato, 

 but onh' after many trials and with feeble growth and 

 weak ferment powers. Tire methane bacterium was not 

 obtained pure in colonies. Neither organism colored 

 blue with iodine. The experiments were begun in 1894 

 and carried through a long series of years, involvin.g an 

 enormous amount ot painstaking labor.
