e one. If left
to themselves, they are often and speedily followed by a refreshing
calm, and cannot be interfered with, as an aggravation of the symptoms,
without damaging the case.

These are all the rules which I have so far been able to infer from my
use of Apis. Further experience will have to decide whether they apply
to all periods, or only to the prevailing type of fever.

I am unable to say whether Apis will prove effectual against epidemic
marsh-intermittents, and if so, how the use of it will have to be
modified. May it please those, who can shed light on this subject, to
communicate their experience!

Two other exceptions to Apis, as a universal febrifuge, have occurred to
me in my practice: _The development of fever and ague in poisoned soil,
and fever and ague complicated with China-cachexia._

It is peculiar to intermittent fever to excite the morbid germs which
are slumbering in the organism. This is more particularly true in
reference to psora. In proportion to universality of the psoric miasm,
fever and ague will develop and complicate itself with psoric
affections; and it is such complications that give rise to the
inveterate character of intermittents and their disorganizing tendency.

In such cases, a cure cannot be effected without some suitable
anti-psoric. During the prevailing fever, Natrum muriaticum has proved
such an anti-psoric, provided it was used as follows: If the signs of
psoric complication became visible at the outset, I gave a pellet of
Natrum mur. 30, and awaited the result until after the third paroxysm.
If symptoms of improvement had become manifest, no other remedy was
given, and the improvement was permitted to progress from day to day. If
the signs of psoric complication were obscure at the beginning of the
attack, Apis was at once given. If no improvement became visible after
the third paroxysm, or if other symptoms developed themselves, this was
looked upon as a proof of the existence of psora, and Natrum mur. 30 was
given, and no other remedy, until after the third paroxysm. Either the
disease had ceased, or it required further treatment. In the latter
case, Apis 3 was continued in drop-doses, morning and evening, until the
patient was decidedly convalescent. No further medicine was given after
this, and the Natrum mur. was permitted to act undisturbed, without a
single repetition. Every such repetition is hurtful; it disturbs the
curative process, excites an excess of r
