Abstract
IN many widely separated tropical countries it has been the rather curious custom of the natives to catch fish in lakes, rivers, and creeks by means of certain poisonous plants; the leaves, stems, or roots being used for this purpose. The water extract obtained by macerating the appropriate part of the plant is poured into the stream, and the fish being rapidly stupefied by it are readily caught. The practice is now generally discouraged, owing to the heavy mortality ensuing amongst the small and immature fish.
