Nitrogen, chlorin, and sulphates in rain and snow, B. Aetis (Cliem. Neics, 

 lis (1916), No. 2928, pp. 3-5). — This is a report of a continuation, during the 

 period from October 12, 1914, to June 19, 1915, of observations previously 

 reported (E. S. R., 32, p. 616). The results are given of determinations of 

 sulphates, nitrates, nitrites, nitrogen as free ammonia, nitrogen as albuminoid 

 ammonia, and chlorin, in 35 samples of rain aiud 16 of snow collected at 

 Mt. Vernon, Iowa. 



The rainfall amounted to 15.35 in. and the snowfall to 37.75 in., equivalent 

 to 18.49 in. of rain. The amounts of different substances brought down per
