the bath, it may be necessary to give an aperient
powder, possibly also to repeat the dose for once or twice every three
hours; in which case the following prescription is to be employed. Take
of

Powdered scammony 6 grains.
Grey powder 6 grains.
Antimonial powder 4 grains.
Lump sugar 20 grains.

Mix thoroughly, and divide into three powders, which are to be taken as
advised for an infant one year old; for younger or weakly infants,
divide into four powders, and give as the other. For thirst and febrile
symptoms, give drinks of barley-water, or cold water, and every three
hours put ten to fifteen drops of spirits of sweet nitre in a
dessert-spoonful of either beverage.

THRUSH, AND ITS TREATMENT.

2523. This is a disease to which infants are peculiarly subject, and in
whom alone it may be said to be a disease; for when thrush shows itself
in adult or advanced life, it is not as a disease proper, but only as a
symptom, or accessory, of some other ailment, generally of a chronic
character, and should no more be classed as a separate affection than
the petechae, or dark-coloured spots that appear in malignant measles,
may be considered a distinct affection.

2524. Thrush is a disease of the follicles of the mucous membrane of the
alimentary canal, whereby there are formed small vesicles, or bladders,
filled with a thick mucous secretion, which, bursting, discharge their
contents, and form minute ulcers in the centre of each vessel. To make
this formal but unavoidable description intelligible, we must beg the
reader's patience while we briefly explain terms that may appear to many
so unmeaning, and make the pathology of thrush fully familiar.

2525. The whole digestive canal, of which the stomach and bowels are
only a part, is covered, from the lips, eyes, and ears downwards, with a
thin glairy tissue, like the skin that lines the inside of an egg,
called the mucous membrane; this membrane is dotted all over, in a state
of health, by imperceptible points, called follicles, through which the
saliva, or mucous secreted by the membrane, is poured out.

2526. These follicles, or little glands, then, becoming enlarged, and
filled with a congealed fluid, constitute thrush in its first stage; and
when the child's lips and mouth appear a mass of small pearls, then, as
these break and discharge, the second stage, or that of ulceration, sets
in.
