r the subsidence of all the
symptoms of the disease, a corrective course of medicine, and a regimen
of exercise, should be adopted for some weeks after the cure of the
disease. To effect this, an active aperient powder should be given every
three or four clays, with a daily dose of the subjoined tonic mixture,
with as much exercise, by walking, running after a hoop, or other bodily
exertion, as the strength of the child and the state of the atmosphere
will admit, the patient being, wherever possible, removed to a purer air
as soon as convalescence warrants the change.

2559. _Tonic Mixture_.--Take of infusion of rose-leaves, 6 ounces;
quinine, 8 grains; diluted sulphuric acid, 15 drops. Mix. Dose, from
half a teaspoonful up to a dessertspoonful, once a day, according to the
ago of the patient.

Scarlatina, or Scarlet Fever.

2560. Though professional accuracy has divided this disease into several
forms, we shall keep to the one disease most generally mot with, the
common or simple scarlet fever, which, in all cases, is characterized by
an excessive heat on the skin, sore throat, and a peculiar speckled
appearance of the tongue.

2561. _Symptoms_.--Cold chills, shivering, nausea, thirst, hot skin,
quick pulse, with difficulty of swallowing; the tongue is coated,
presenting through its fur innumerable specks, the elevated papillae of
the tongue, which gives it the speckled character, that, if not the
invariable sign of scarlet fever, is only met with in cases closely
analogous to that disease. Between the _second_ and __third_ day, but
most frequently on the _third_, a bright red efflorescence breaks out in
patches on the face, neck, and back, from which it extends over the
trunk and extremities, always showing thicker and deeper in colour
wherever there is any pressure, such as the elbows, back, and hips; when
the eruption is well out, the skin presents the appearance of a boiled
lobster-shell. At first, the skin is smooth, but, as the disease
advances, perceptible roughness is apparent, from the elevation of the
rash, or, more properly, the pores of the skin. On the _fifth_ and
_sixth_ days the eruption begins to decline, and by the _eighth_ has
generally entirely disappeared. During the whole of this period, there
is, more or less, constant sore throat.

2562. The _Treatment_ of scarlet fever is, in general, very simple.
Where the heat is great, and the eruption comes out with difficulty, or
