.--Isolation means the complete seclusion of the
patient in a room by himself, so that no one will see him or come in
contact with him except the physician and the nurse or mother who will
tend him during the entire course of the disease. Isolation implies more
than it would seem to mean. It implies that every article used during
the sickness will be thoroughly disinfected before it leaves the room in
which the patient himself is isolated. Mothers must always remember that
every article used by the patient may carry the germs of the disease to
some other member of the family or to some other individual. These
articles are the clothing of the child, the bedclothes, napkins,
handkerchiefs, towels, dishes, knives and spoons, rags, the various
discharges--sputum, urine, and bowel passages--and, we may add to this
list, flies, insects, and domestic animals. Every precaution must,
therefore, be taken to safeguard any dissemination of the disease by
means of these articles.

Thorough isolation also implies that the nurse shall frequently bathe
and disinfect her person and her clothing, and that the sick-room itself
shall be carefully dusted with a moist cloth and disinfected from time
to time.

The Contagious Sick-Room.--The contagious sick-room will be prepared
in exactly the same way as the ordinary sick-room which has been
previously described. In addition, however, it will be safeguarded in
the following manner. A wet sheet will be hung up outside the door. This
sheet will be kept constantly moistened with a solution of chloride of
lime. One-half pound to an ordinary house-pail of water is the strength
of the solution to use. Every window must be effectively screened to
prevent the ingress and egress of flies and other insects.

Conduct and Dress of the Nurse.--She will remain in the sick-room all
the time unless when she takes outdoor exercise. Her dress will consist
of a long gown which will entirely cover her person from the neck to the
shoes and will be of plain, white, easily washed material, without tucks
or ruffles or adornment of any kind. She should wear an ordinary pair of
house slippers made of light leather. Her cap will be large enough to
cover and include her hair and head. When she leaves the room, she will
remove her cap, gown, and slippers, disinfect her hands in a
disinfecting solution and wash her face, neck, and hands in soap and
water. She should go directly out and in, without coming in contact with
