animal model which the interested chemist would find necessary 
in monitoring his isolation work; and 2) the sparsity of field 
work of a scientific nature in the fast disappearing aboriginal 
societies. Further ethnobotanical field work will surely lead to 
the discovery of additional hallucinogenic plants and to more 
information on those already known. 
The Plant Kingdom remains a fertile and almost virgin 
territory for those interested in the discovery of new psycho- 
active drugs, not to mention other types of biologically active 
compounds waiting in silent hiding. Can we afford to neglect 
any longer the hunting ground that until now has provided, 
mainly through folklore and serendipity, leads that the pharma- 
ceutical industry has turned into products having annual sales in 
excess of $3,000,000,000 in the American prescription market 
alone? (Farnsworth and Morris 1976).
