Does the skin exert a great influence in removing disease from the
internal organs, as well as in keeping them in health? Give an
illustration 996. Why should every sick person, particularly, breathe
pure air?

_Illustrations._ 1st. In 1833, I was called, in consultation with
another physician, to Mr. H., who was much debilitated, and delirious.
For several successive days he had not slept. His room was kept very
warm and close, for fear he would "take cold." The only change that I
made in the treatment, was to open the door and window, at a distance
from the bed. In a short time, the delirium ceased, and he fell into a
quiet slumber. From this time he rapidly recovered, and the delirium
was probably the result of breathing impure air.

2d. Formerly, every precaution was used to prevent persons sick of the
small-pox from breathing fresh air. When Mrs. Ramsay had this disease
in Charleston, S.C., her friends, supposing that life was extinct,
caused her body to be removed from the house to an open shed. The pure
air revived the vital spark. The result probably would have been
different, had she been kept a few hours longer in the vitiated air.

997. The influence of habit should not be disregarded in the removal
of disease. If food or drink is to be administered, however small in
quantity or simple its quality, it should be given at or about the
time when the ordinary meals were taken in health.

998. Again, the usual time when the patient was in the habit of
retiring for sleep should be observed, and all preparation necessary
for the sick-room during the night should be made previous to this
hour. Efforts should also be made to evacuate the waste matter of the
digestive and urinary organs at the period which habit has formed in
health. This is not only a remedial agent in disease, but often
precludes the necessity of laxative or drastic cathartics.
