under a well conducted course of hydriatic treatment is, in general, favorable. Much depends, however, on the season of the year (in damp and cold weather--partly owing to a lack of pure air in the sick-room--the disease is more dangerous than in summer); on the general health of the patient (not on his mere looks, for well-fed and stout children are subject to affections of the brain); on the age of the patient (adults are generally more in danger than children); on the form of the disease and the character of the fever (erethic or mild fever being the most favorable, whilst typhoid fever is the worst; a violent character of the fever is not very dangerous under hydriatic treatment, as we have plenty of means to limit its ravages without weakening the patient); on the eruption, the condition of the throat, the process of desquamation, &c.
are the following: Absence of internal inflammation; a bright florid rash; a regular, steady appearance, standing out, and disappearance of the latter; a regular and complete pealing off of the cuticle; a decrease of the pulse after the eruption of the rash; an easy and regular respiration; a natural expression of the features; a moist skin.
are: A fetid breath, with ulceration and sloughing of the throat and glands; a smarting and weakening diarrhoea; involuntary evacuations of the bowels; dizziness, deafness, coma, grinding of the teeth; retention of urine; petechiæ; a rapid decline of the patient's strength; a quick, small, weak pulse; rapid breathing; twitchings, tetanus, hiccough, &c.--Closing up of the nose frequently precedes a dangerous affection of the brain. A sudden disappearance of the rash, or of the inflammation of the throat, is a bad omen. With such symptoms as these, there is usually little or no rash, and the little there is, of a pale, livid color, and the skin, in general, inactive.
[1] The expression _scarlatina_ does not imply, as it is believed by many, on account of its diminutive form, a peculiar mild form of the disease: it is nothing but the Latin and scientific name for scarlet-fever.
