PRUSSIC ACID IN THE LEGUMINOS^ 



237 



Investigations have been made of peas which have been 

 pounded up and digested in water. 



At the same time it should be remarked that even some 

 edible peas contain very small quantities of prussic acid. 



Above is a highly interesting table on the prussic acid 

 content of various peas from Java, Mauritius, Burma, 

 France, and Madagascar. For purposes of comparison 

 analyses made by Dunstan, Guignard, Kohn Abrest, and 

 Tatlock have been tabulated. 



A few samples obtained from London merchants and 

 examined at the Imperial Institute have given : —

Other samples from London and Paris of white and black 

 Algerian beans, reddish-black beans and Danube peas have 

 given negative results.
