lacrymal sack with ideas of tender pleasure, or

XI. The secretion of sensorial power in the brain is probably increased by
opium or wine, because when taken in certain quantity an immediate increase
of strength and activity succeeds for a time, with consequent debility if
the quantity taken be so great as to intoxicate in the least degree. The
necessity of perpetual respiration shews, that the oxygen of the atmosphere
supplies the source of the spirit of animation; which is constantly
expended, and is probably too fine to be long contained in the nerves after
its production in the brain. Whence it is probable, that the respiration of
oxygen gas mixed with common air may increase the secretion of sensorial
power; as indeed would appear from its exhilarating effect on most
patients.
