Besides this purely local ailment, there is another skin affection which is seen over the body generally, and is known popularly by the name of _red gum_, or in Latin _strophulus_. I mention the Latin name because I have known persons sometimes, misled by the similarity of sound, fancy that it had some connection with scrofula. It is met with less commonly now than formerly, when people were accustomed to keep infants unduly wrapped up, and to be less careful than most are now-a-days about washing and bathing. It depends on over-irritation of the sweat glands of the delicate skin of the infant, the result of which shows itself in the eruption on the body and face of a number of small dry pimples sometimes surrounded by a little redness, itching considerably, and when their top has been rubbed off by scratching having a little speck of dried blood at their summit. A rash like this, a sort of _nettle rash_, more blotchy and causing little lumps on the skin, which in a day or two come and go, sometimes appears in the intervals between the pimples, sometimes takes their place, and causes, as they do, much irritation. This nettle rash is usually dependent on some error of diet, on some acidity of the stomach, and, on their being corrected soon passes away, leaving the pimples as they were before, but sometimes being reproduced if the pimples cause excessive irritation of the tender skin. The matter of chief importance for a mother to know, is that these rashes have no serious signification. Their treatment is very simple. It consists in dressing the child very lightly, in bathing it very frequently with tepid water, avoiding as far as may be the use of soap, and in sponging it often to relieve the irritation with some simple alkaline lotion; such for instance as one recommended by the late Dr. Tilbury Fox, and which is composed of twenty grains of carbonate of soda, two teaspoonfuls of glycerine, and six ounces of rose water. Of course if the stomach is out of order that must be attended to, but a little fluid magnesia, once or twice a day, is all that is usually needed in the way of medicine. One other affection of the skin, very common, very distressing, very tedious, of which there are many varieties, generally known by the technical name of _eczema_, from a compound Greek word which signifies to flow, needs that I should say something about it. It is not limited in its occurrence to infancy, nor does it of necessity cease when childhood is over, but continues to recur even in grown persons, and shows itself still from time to time even in the aged.
