marked by a chill or a series of chills, which alternate with flushes of
heat. In this stage the tongue becomes coated, there is also nausea and
vomiting, pain in the limbs, back, and particularly in the loins, the
latter symptom being of diagnostic importance. This stage continues
about two days, and if the symptoms are light, it may be expected that
the disease will be comparatively mild, and of the _distinct_ variety.

_The stage of eruption._ The eruption begins to appear on the skin,
generally on the third day following the attack, though in the throat
and mouth may be discovered round, whitish, or ashy spots, several hours
previous to the appearance of vesicles on the surface of the body. These
are first seen on the face and neck, then on the trunk and upper
extremities, and, lastly, on the lower extremities. The eruption at
first appears in the form of small, red or purple spots, which change
the texture of the skin by becoming more hard, pointed, and elevated. On
the fifth day of the eruption they attain their full size, being
softened and depressed in the center, and hence are called
_umbilicated_. Now a change takes place, and the vesicles fill with
"matter" and become pointed, and there is a rise in the fever.

_The stage of suppuration_ commences thus: the pulse quickens, the skin
becomes hotter, and in many cases of the confluent variety, swelling of
the face, eyelids, and extremities occurs. Frequently there is passive
delirium in this stage, and if diarrhea sets in, it is an unfavorable
sign. The duration of this stage of the eruption is four or five days.

_The stage of desication_, or of the drying of the pustules, commences
between the twelfth and fourteenth day of the disease. In the confluent
variety, patches of scab cover all the space occupied by the eruption,
and the skin exhales a sickening odor.

THE TREATMENT should have reference to the determination of the eruption
to the surface. If there is thirst, allow cold drinks, ice-water, or
lemonade. Bathing the surface with cold water, breathing plenty of fresh
air, using disinfectants in the room, and taking antiseptic medicine
internally, are proper. Add one part of carbolic acid to six parts of
glycerine, mix from two to three drops of this with an ounce of water,
and of this preparation administer teaspoonful doses frequently. A few
drops of carbolic acid and glycerine may be rubbed up with vaseline, and
the surface anointed with it to prevent
