o the time-honored constitutional authority
of this great panacea in the class of cases to which he has devoted his
brilliant intelligence. Still, there is no telling what evils have
arisen from the abuse of this mineral. Dr. Armstrong long ago pointed
out some of them, and they have become matters of common notoriety. I am
pleased, therefore, when I find so able and experienced a practitioner as
Dr. Williams of this city proving that iritis is best treated without
mercury, and Dr. Vanderpoel showing the same thing to be true for
pericarditis.

Whatever elements nature does not introduce into vegetables, the natural
food of all animal life,--directly of herbivorous, indirectly of
carnivorous animals,--are to be regarded with suspicion. Arsenic-eating
may seem to improve the condition of horses for a time,--and even of
human beings, if Tschudi's stories can be trusted,--but it soon appears
that its alien qualities are at war with the animal organization. So of
copper, antimony, and other non-alimentary simple substances; everyone of
them is an intruder in the living system, as much as a constable would
be, quartered in our household. This does not mean that they may not, any
of them, be called in for a special need, as we send for the constable
when we have good reason to think we have a thief under our roof; but a
man's body is his castle, as well as his house, and the presumption is
that we are to keep our alimentary doors bolted against these perturbing
agents.

Now the feeling is very apt to be just contrary to this. The habit has
been very general with well-taught practitioners, to have recourse to the
introduction of these alien elements into the system on the occasion of
any slight disturbance. The tongue was a little coated, and mercury must
be given; the skin was a little dry, and the patient must take antimony.
It was like sending for the constable and the posse comitatus when there
is only a carpet to shake or a refuse-barrel to empty. [Dr. James Johnson
advises persons not ailing to take five grains of blue pill with one or
two of aloes twice a week for three or four months in the year, with half
a pint of compound decoction of sarsaparilla every day for the same
period, to preserve health and prolong life. Pract. Treatise on Dis.
of Liver, etc. p. 272.] The constitution bears slow poisoning a great
deal better than might be expected; yet the most intelligent men in the
profession have gradually got out of t
