322 EXPERIMENT STATION RECORD. 



FERMENTATION— BACTERIOLOGY. 



Report of the agricultural-bacteriological laboratory, 1896, A. 



Theoktistov (8elsl\ Khoz. i Lyesov, 185(1897), Jan.^pp. 1-4). — The work 

 of the Government laboratory during the year 1896 was confined mainly 

 to studies of cultures of bacilli which kill field mice. Preparations were 

 completed for field experiments in the destruction of marmots (Sper- 

 mopMlusfulvus) through the agency of bacteria. Four species of bacteria 

 were studied both microscopically and biologically. The investigation 

 is to be published in detail later. The number of shipments of these 

 bacteria cultures to correspondents and the amount of culture shipped 

 is noted. Experiments were also made to determine whether the dis- 

 ease caused by these bacteria is transmitted by means of the excrement 

 of diseased mice. It was found that the disease was readily trans- 

 mitted in this way. A more complete account of the results is to be 

 given later. — P. fireman.
