Kainit. 

 A coinmercial sample of Kainit was emploj^cd. It was 

 dried at 100"^ in a water oven. When dry it contained 4 • 8 x>er 

 cent, of insoluble matter. This should therefore be deducted 

 from the percentages given below. The percentage which 

 inhibits germination is therefore 14-0-67 = 13-33, for this 

 particular sample. The 17 percent, solution was not alkaline. 



Temperatvire, 73-81" F. 



Common Salt. 

 Ordinary Table Salt, dried at 100° C, was used. 



Temperature, 73-81° F. 

 PeniciUium grew subsequently in the 7, 8, and 9 per cent, 

 solutions on keeping.
