HYDROCYANIC ACID IN PLANTS, ii., 



part of the work much credit is due to my collaborators. 



The grasses were tested in a similar manner to the plants re- 



corded in Part i. (These Proc. xxxvii., 1912, 220). 



(1) grass 



in vapour of chloroform, for presence of cyanogenetic compounds 

 and free hydrocyanic acid, (2) grass and emulsin, in case of 

 enzyme deficient or absent, and (3) grass and amygdalin, for pre- 

 sence of /3 enzymes. 



These three tests are represented respectively by the three signs 

 in each column.
