Dr. Blake inhaled about six quarts of the air, was affected during
the process of respiring it with a slight degree of vertigo, which
was almost immediately succeeded by a thrilling sensation extending
even to the extremities, accompanied by a most happy state of mind and
highly pleasurable ideas. He felt a great propensity to laugh, and
his behaviour in some measure appeared ludicrous to those around him.
Muscular power seemed agreeably increased, the pulse acquired strength
and firmness, but its frequency was somewhat diminished. He perceived
rather an unpleasant taste in the mouth and about the fauces for
some hours afterwards, but in every other respect, his feelings were
comfortable during the remainder of the day.
