and, upon emerging from that of the lowest
temperature, he experiences a delightful sensation of vigor and
elasticity.

As a hygienic agent, the hot-air bath has been' constantly growing in
favor. Its value is now recognized by all physicians throughout the
world. The judicious use of the Turkish bath serves to secure perfect
equalization of the circulation. Glandular activity is increased,
elasticity and power given to the muscles, and a permanent, stimulating
and tonic influence imparted to the system, a condition at once
conducive to the enjoyment and prolongation of life. Dr. Erasmus Wilson,
of England, says, in a paper read before the London Medical Association:
"The inhabitant of a large city would live as healthy, immured within
city walls, as amid the fields and meadows of the country. His bath
would be to him in the place of a country house or horse--it would give
him air, exercise, freshness, health, and life."

"The bath that cleanses the inward as well as the outward man; that is
applicable to every age; that is adapted to make health healthier, and
alleviate disease, whatever its stage or severity, deserves to be
adopted as a national institution, and merits the advocacy of all
medical men; of those whose especial duty it is to teach how health may
be preserved, and how disease may be averted."

The hot, _dry_ atmosphere of the Turkish bath promotes rapid evaporation
from the surface of the body, and it is well known that rapid
evaporation from the surface is a cooling process. A person's finger may
be frozen in one minute's time, by throwing upon it a constant, fine
spray of rhigolene or sulphuric ether. The rapid evaporation of the
light fluid congeals the liquids of the tissues and a film of ice is
rapidly formed upon the part. In a less intense degree the same cooling
process is carried on over the whole surface of a person, when in the
hot room, or _sudatorium_, of the Turkish bath. The evaporation from the
surface is so rapid that one can hardly appreciate the profuseness of
the perspiration going on. The evaporation from the surface so rapidly
carries off the heat from the body that one finds himself able, with
little or no inconvenience, to remain in a room heated to from 180 deg. to
200 deg. or even 220 deg. Fahr.

As a hygienic measure to be regularly or occasionally employed by
persons in fair health, the Turkish or hot dry-air bath is far superior
to the Russian or vapor-bath. (1.) It produc
