This is an eruptive disease, which is found occasionally on the face, neck, arms or shoulders, but most frequently on the head. The disease usually occurs in circular patches which appear to increase in rings or circles, whence the name. The patch is composed of little vesicles, redder in colour than the natural skin. These vesicles usually break in about three or four days, and form little scabs, which dry up and fall off. The vesicles, however, are very apt to spread, and, if neglected at the commencement, may become very troublesome to eradicate. Ringworm is highly contagious; it is frequently propagated by children at school wearing each other's caps, or by using the same comb; also, sometimes, it may be transferred from one part to another of the same child from scratching or picking the original patch.
When the Ringworm is first discovered, the hair on and around the part should be clipped quite close with a pair of sharp scissors. The place should then be carefully washed with a little soap and warm water, on a piece of soft flannel; when dry, each little vesicle (or pimple) should be touched with a drop of Muriated Tincture of Iron, (Tinct. Ferri Mur.), on the point of a camel's hair brush, or the point of a small feather. This should be repeated every morning till the disease disappears. I have never known a case resist this mode of treatment. A cap should be worn con-etantly, so as to prevent any irritation to the part, and also to prevent the child rubbing or scratching it.
