Lather of this soap, made in this way, may be spread on the most sensitive sores (when ulcers have eaten through both outer and inner skins) with only a very slight feeling of smarting to the patient, and with the most healing effect. It is very different with soda soap made in the usual way. When the skin of the head has got inflamed (as we saw in the case of a child the other day, where the back of the head was a matted mass of most distressing sores), it is charming to see the effect of this lather. We took a number of handfuls of it, and soaked the matted hair and inflamed skin till the poor child looked up with an expression of astonished relief. Legs, Pricking Pains in.--Sometimes curious pricking pains are felt in the legs, becoming so severe as even to confine a patient to bed. Nothing can be seen on the skin, and no swelling or other visible sign of trouble is present. Evidently this requires treatment more particularly of the nerves, which go to maintain a proper balanced state of feeling in the skin where the pricking is felt. The patient must give up using alcohol in any form, and should rest in bed. In treatment we do not look to the skin itself, but rather to the nerves, to effect a cure. There is a failure at the nerve roots, and indeed the patient will usually be weak and nervous generally. A popular remedy in such a case might be arsenic, which must be avoided, as likely greatly to injure instead of help. The cure is in increased nutrition of the nerve substances, by rest and light dietary. _See_ Biscuits and Water, Diet.
