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.
