This is the doctrine of the true church on the subject of opium: of which
church I acknowledge myself to be the only member--the alpha and the
omega: but then it is to be recollected that I speak from the ground of a
large and profound           experience: whereas most of the unscientific
{13} authors who have at all treated of opium, and even of those who have
written expressly on the materia medica, make it evident, from the horror
they express of it, that their experimental knowledge of its action is
none at all.
