y be a danger to others).

The New York press accepts the situation philosophically; as follows:

"Infantile Paralysis cannot be cured by means of medicines. The
physician must of necessity limit his ministrations to easing the
pain, providing for easy movement of the bowels and so forth, but
otherwise _he must let nature take its course_."

Medical reference books vaguely define the disease with diverse and
indefinite theories, showing that science on the subject is practically
mute.

But the medically "unprofessional," random remark of the New York
press-man has exactly hit the mark: "Let nature take its course."

The fact is that nothing very clear or absolute can be said about
Infantile Paralysis; for observation shows that it is apparently a
matter of racial conditions and environment and that only from the
general application of the Laws of Nature, as taught by biology can we
reasonably hope to solve the problem or cure the disease.

As the result of careful study of many cases I simply confirmed the fact
that Infantile Paralysis belongs strictly to the class in which in the
foregoing chapter I have placed it, and is subject to the same rules,
influences and treatment. In most of the cases treated I have not failed
to discover the existence of spinal trouble in one or other of the
parents. This, engendering _predisposition_ to similar complaints _in
the children of the opposite sex_, which, acted upon by the irritants
bred of poor or irrational nutriment and unhygienic environment in
greater or lesser degree, results in attacks of this disease, in plain
or epidemic form as the case may be, to which all children so
predisposed are liable. Thus, incidentally, is my recently discovered
"Law of the Cross-Transmission of Characteristics" amply verified.

As to the cause which leads to the development of this predisposition in
the children, the answer, of course, is improper nourishment; and
amongst the contributory causes I would specially indicate,
"Pasteurized" and "sterilized" milk which has been absolutely banned by
science on the basis of Physical Chemistry, according to which it was
definitely proved in a report laid before the Paris Academy of Sciences,
that valuable bone-forming ingredients in the milk, (a combination of
carbonic and phosphoric lime,) are lost in course of Pasteurization,
since at the temperature necessary for the process they are _transmuted
by heat into insoluble elemen
