mprises those who have lived reasonably, and who, if
annoyed by imperfect digestion, have sought relief by ascertaining and
by abandoning the errors from which it sprang."

Among the most pernicious and dangerous of all the patent medicines on
the market are the so-called "Headache Powders," whose almost
instantaneous effects testify to the potency of the drugs they contain.
Such powerful agents carry their own condemnation, for they cannot in
the nature of things _remove the cause_ of the pain; hence their action
is limited to narcotising the nerves. The disease continues, the damage
goes on, but the faithful sentinels are put to sleep. These headache
powders so increased the deaths from heart failure in New York City a
couple of years ago that it became necessary to warn the public against
them.

Memory, Loss of.--A more or less complete suspension of this faculty is
a not uncommon form of mental and bodily illness. We do not so much
mean the mere fading of past impressions as the loss of power to recall
them, so that we cannot recall what we wish to remember. This is a
result of any serious bodily weakness. It will come on through any
exhausting exertion, or prolonged and weakening illness. Stomach
disorder will also cause it. In this last case, drinking a little hot
water at intervals will usually put all right. A cup of very strong tea
will so derange the stomach in some cases as to cause temporary
suspension of memory. We mention these cases to prevent overdue alarm
at a perhaps sudden attack. The loss of mental power in such cases does
not always mean anything very serious.

Just as the stomach affects the memory, so also much use of memory and
mental strain tells severely upon the stomach. Digestive failures in
strictly temperate persons often arise from an overstrain of the mind.

We explain these two actions, the one of body on mind, and the other of
mind on body, so that care may be taken, on both sides, of the complex
nature we possess. If this is done, there will be little chance of
memory failing.

Mind in Disease.--Often a person, because of physical failure, becomes
possessed of an utterly erroneous _idea_, which no reasoning can change
or remove. Indeed, reasoning in such cases is best avoided. Attention
should rather be directed to the physical cause of the mental state,
with a view to its removal. Very probably you will find there is want
of sleep, with a dry hard state of the skin of the hea
