[71] The deleterious effect of Cocculus Indicus (the fruit of the
memispermum cocculus) is owing to a peculiar bitter principle contained
in it; which, when swallowed in minute quantities, intoxicates and acts
as poison. It may be obtained from cocculus indicus berries in a
detached state:--chemists call it picrotoxin, from +pichros+, bitter;
and +toxichon+ poison.

_Counterfeit Tea-Leaves._

The late detections that have been made respecting the illicit
establishments for the manufacture of imitation tea leaves, arrested,
not long ago, the attention of the public; and the parties by whom these
manufactories were conducted, together with the numerous venders of the
factitious tea, did not escape the hand of justice. In proof of this
statement, it is only necessary to consult the London newspapers (the
