n all cases of fever the diseased matter is
dissolved in the hot feverish blood and circulates in and with it. The
evaporation of the skin is increased, and with it the diseased matter is
absorbed by the compresses, which consequently diffuse an unpleasant
odor when removed, and when cleansed, give to the water a muddy
appearance. Thus it may be observed to what extent the pack removes
diseased matter from the body.

Packs must be changed as soon as they cease to give comfort to the
patient, and make him too warm. Highly flushed cheeks, increasing
temperature and unrest are sure signs that the pack requires to be
changed, and in case of high fever this may happen after 20 to 30
minutes.

For short packs, such as are prescribed in all inflammatory and feverish
diseases, water at from 59 degrees to 64 degrees is used.

A piece of linen cloth is folded from 4 to 8 times, wrung out, but not
too much, and then covered with moderately thick folds of woollen cloth.
The stronger the patient and the higher the fever, the thicker should be
the pack.

For infants a double linen strip is sufficient.

The faster the fever and inflammation recede, the longer may the pack
last, up to three hours. The convalescent will enjoy the moist warmth,
under the influence of which still existing diseased material is
thoroughly dissolved and completely excreted. The dissolving effect of
packs of long duration is most noticeable in chronic diseases.

Through the penetrating effect of the moist warmth on the body or parts
thereof, deposited diseased matter is dissolved, and dislodged, existing
excoriations are disintegrated, and withdrawn into the circulating
blood, and thus excreted.

The dissolving packs of long duration must be applied somewhat thinner
than the cooling ones (from 1 to 3 folds); they must be wrung out more
vigorously, and covered more closely.

If a pack should be applied for the sake of prevention of disease, it
may be put on in the evening and remain all night. In the beginning of
fever, while it remains moderate, the patient can endure the pack for
from 2 to 2-1/2 hours.

Biological hygienic therapy rejects the external application of ice, for
it causes severe congestion of the blood. Extensive application of the
ice pouch causes more or less paralysis of the nerves, which in many
cases prevents recovery and even causes chronic disease or fatal
results. The biological hygienic treatment desires _to moderate
