Says Professor B. R. Peaslee, MD., of the same school: "The
administration of powerful medicines is the most fruitful cause of
derangements of the digestion."

Says Professor H. G. Cox, M.D., of the same school: "The fewer
remedies you employ in any disease, the better for your patients."

Says Professor E. H. Davis, M.D., of the New York Medical College:
"The modus operandi of medicines is still a very obscure subject. We
know that they operate, but exactly how they operate is entirely
unknown."

Says Professor J. W. Carson, M.D., of the New York University Medical
School: "We do not know whether our patients recover because we give
medicines, or because Nature cures them."

Says Professor E. S. Carr, of the same school: "All drugs are more or
less adulterated; and as not more than one physician in a hundred has
sufficient knowledge in chemistry to detect impurities, the physician
seldom knows just how much of a remedy he is prescribing."

The authors disagree in many things; but all concur in the fact that
medicines produce diseases; that their effects are wholly uncertain,
and that we know nothing whatever of their modus operandi.

But now comes in the testimony of the venerable Professor Joseph M.
Smith, M.D., who says: "Drugs do not cure diseases; disease is always
cured by the vis medicatrix naturae."
