found to possess cyanogenetic properties, i. e., would yield hydrocyanic 

 acid ("prussic" acid) upon suitable treatment. 



That this might be expected was, in a measure, suggested by the 

 symptoms observed in the feeding experiments. In the literature it 

 appears that Greshoff 1 found from 0.02% to 0.6% of hydrocyanic acid

in Triglochin maritima. Later Blanksma 2 in working with the same 

 plant found hydrocyanic acid in amounts varying from 0.056% to 

 0.184%,^
