sopition

noun

1. (obsolete, uncountable)The act of putting to sleep.

   “But as for dementation, sopition of reason, and the diviner particle from drink, though American religion approve, and Pagan piety of old hath practised, even at their sacrifices; Christian morality and the doctrine of Christ will not allow.”

   “The fresh, loose opium pill will narcotize quickly; the old, compact, dry one will dissolve very slowly, act locally, produce little sopition, and thus be more effective as a contraria for a certain kind of diarrhœa.”
