SUMMARY. 



The above list contains the names of about 300 native 

 plants, representing sixty-five Natural Orders. Twenty-nine 

 plants gave positive results, in which hydrocyanic acid was 

 liberated by the natural ferment in the plant. Seven exotic 

 plants are also recorded for the first time, as containing cya- 

 nogenetic glucosides. 



The N.O. Gramineae has been reserved for a separate paper.
