urable state is indicated by an excessive flow of saliva, or what is
called "dribbling," and by a considerable amount of relaxation of the
bowels-a condition that must not be mistaken for diarrhoea, and checked
as if a disease, but rather, for the day or two it continues, encouraged
as a critical evacuant.

2535. Should there be much debility in the convalescence, half a
teaspoonful of stee wine, given twice a day in a little barley-water,
will be found sufficient for all the purposes of a tonic. This, with the
precaution of changing the child's food, or, when it lives on the
mother, of correcting the quality of the milk by changing her own diet,
and, by means of an antacid or aperient, improving the state of the
secretion. Such is all the treatment that this disease in general
requires.

2536. The class of diseases we are now approaching are the most
important, both in their pathological features and in their consequences
on the constitution, of any group or individual disease that assails the
human body; and though more frequently attacking the undeveloped frame
of childhood, are yet by no means confined to that period. These are
called Eruptive Fevers, and embrace chicken-pox, cow-pox, small-pox,
scarlet fever, measles, milary fever, and erysipelas, or St. Anthony's
fire.

2537. The general character of all these is, that they are contagious,
and, as a general rule, attack a person only once in his lifetime; that
their chain of diseased actions always begins with fever, and that,
after an interval of from one to four days, the fever is followed by an
eruption of the skin.

CHICKEN-POX, OR GLASS-POX; AND COW-POX, OR VACCINATION.

2538. CHICKEN-POX, or GLASS-POX, may, in strict propriety, be classed as
a mild variety of small-pox, presenting all the mitigated symptoms of
that formidable disease. Among many physicians it is, indeed, classed as
small-pox, and not a separate disease; but as this is not the place to
discuss such questions, and as we profess to give only facts, the result
of our own practical experience, we shall treat this affection of
glass-pox or chicken-pox, as we ourselves have found it, as a distinct
and separate disease.

2539. Chicken-pox is marked by all the febrile symptoms presented by
small-pox, with this difference, that, in the case of chicken-pox, each
symptom is particularly slight. The heat of body is much less acute, and
the principal symptoms are difficulty of breathing, headache
