der your chilling patient's tongue, it will usually register anywhere

This method of attack is especially common, not only in influenza, but
also in all the other so-called "common colds." In fact, when we begin
to shiver and sneeze and hunt around for an imaginary draft or lowering
of the temperature which has caused it, we are actually in the first
stage of the development of an infection which was contracted hours, or
even days, before.

When you begin to shiver and sneeze and run at the eyes you are not
"catching" cold; you have already caught it long before, and it is
beginning to break out on you. Mere exposure to cold will never cause
sneezing. It takes a definite irritation of the nasal mucous membrane,
by gas or dust from without, or toxins from within, to produce a sneeze.

As to mere exposure to cold weather and wet and storm being able to
produce it, it is the almost unanimous testimony of Arctic explorers
that, during their sojourn of from two to three years in the frozen
North, they never had so much as a sneeze or a sore throat, even though
frequently sheltered in extemporized huts, and running short of adequate
food-supply before spring. Within a week of their return to civilization
they would begin sneezing and coughing, and catch furious colds.

Lumbermen, trappers, hunters, and prospectors in Alaska give similar
testimony. I have talked with scores of these pioneers, visiting them,
in fact, in their camps under conditions of wet, cold, and exposure that
would have made one afraid of either pneumonia or rheumatism before
morning, and found that, so long as they remained up in the mountains or
out in the snow, and no case of influenza, sore throat, or cold happened
to be brought into the camp, they would be entirely free from coughs and
colds; but that, upon returning to civilization and sleeping in the
stuffy room of a rude frontier hotel, they would frequently catch cold
within three days.

One unusually intelligent foreman of a lumber camp in Oregon told me
that an experience of this kind had occurred to him three different
times that he could distinctly recollect.

It is difficult to catch a cold or pneumonia unless the bacilli are
there to be caught. Boswell has embalmed for us, in the amber of his
matchless biography, the fact that it had been noted, even in those
days, that the inhabitants of one of the Faroe Islands never had colds
in the head except on the rare occa
