TABLE I 



Averages of the Production of Acid iy Bacillus 

 coli communis 



TABLE II 



Averages of the Production of Acid by Bacillus 

 coli aerogenes 



TABLE III 



Averages of the Production of Acid by Bacillus 

 coli acidi lactici 



1 Each result is the average of ten titrations. 



2 Each result is an average of ten titrations. 



3 Each result is an average of ten titrations. 



Conclusion 

 From the tables of averages it may be seen 

 that storage for a period of 14 weeks in steril- 

 ized Hudson River water (in tidal area) has 

 very little effect upon the amount of acid pro- 

 duced in dextrose, lactose, saccharose, maltose, 

 mannite, salicin and raffinose by various mem- 

 bers of the Bacillus coli group, i. e.. Bacillus 

 coli communis^ aerogenes and acidi lactici, 

 which indicates that production of acid is a 

 permanent characteristic of the Bacillus coli 

 group. The slight decline of acid production 

 may be due to diminished vitality of the organ- 

 isms as a result of long storage in the water.

The twenty-eighth annual convention of 

 the Association of American Agricultural Col- 

 leges and Experiment Stations, held at Wash- 

 ington, D. C, ISTovember 11-13, 1914, and ac- 

 companied as usual by meetings of about half 

 a score of related organizations, brought to- 

 gether college presidents, experiment station 

 and extension directors, and workers in many 

 fields of agricultural science to the number of 

 approximately five hundred. The sessions of 

 the various bodies were well attended and en- 

 thusiastic, and the programs included much 

 of interest to educators, scientific men and the 

 general public. 



The complete list of organizations included 

 in these meetings was as follows: American 

 Association of Farmers' Institute Workers, 

 November 9-11; American Farm Manage- 

 ment Association, November 9, 10; American 

 Society of Agronomy, November 9, 10; Na- 

 tional Association of State Universities, No- 

 vember 9, 10; American Association for the 

 Advancement of Agricultural Teaching, No- 

 vember 10 ; Society for the Promotion of Agri- 

 cultural Science, November 10; American So- 

 ciety of Animal Production, November 10,
