A, OR SORE-THROAT SCARLET-FEVER.

Wherever the _throat_ is affected, which is almost always the case, the
disease is called _scarlatina anginosa_, or _sore-throat scarlet-fever_.
This is the form described at the commencement of this article. There
are several varieties, however, of scarlatina anginosa.

In any case, the organism, invaded by the contagious poison, will try to
rid itself of its enemy. The reaction is necessarily in proportion to
the violence of the miasma and to the quantity of organic power
struggling against it.

11. MILD REACTION (ERETHIC).

If the poison is not virulent, and the body of the patient in a
favorable condition, the _reaction_ is _mild_, and the poison is
eliminated without any violent efforts on the part of the organism. This
is the case in scarlatina simplex, and in mild forms of scarlatina
anginosa.

12. VIOLENT REACTION (STHENIC).

If both, the contagious poison and the organism, are very strong, a
_violent reaction_ will take place, and the safety of the patient will
be endangered by the very violence of the struggle, by which internal
organs may be more or less affected.

13. TORPID REACTION (ASTHENIC).

The more violent the contagious poison, and the weaker the organic
power, the less decidedly and the less successfully will the organism
combat against the poison, and the more inroad will the latter make upon
the system, affecting vital organs and paralyzing the efforts of the
nervous system by attacking it in its centres. In such cases of _torpid
reaction_, the patient frequently passes at once into a _typhoid state_.
This is what we call _scarlatina maligna_, or _malignant scarlet-fever_.

14. SCARLATINA MILIARIS

Sometimes the red patches of the rash are covered with small vesicles of
the size of mustard-seed, which either dry up or discharge a watery
liquid, leaving thin white scurfs, that come away with the cuticle
during desquamation. Although this form, called _scarlatina miliaris_,
being the result of exudation from the capillary vessels, shows an
intensely inflamed state of the skin, its course is usually mild and its
issue favorable; because the morbid poison comes readily to the
surface.

15. SCARLATINA SINE EXANTHEMATE.

There are also mild cases of scarlet-fever, when little or no rash
appears, and the throat is very little affected. These are the result of
a particularly mild character of the epidemy, together with a peculiar
condition of the
