III.—Leloir has found the following of service. Clean the affected part with green soap or with alcohol, and then apply several coats of the following:
| Acid chrysophanic | 15 parts |
| Chloroform | 100 parts |
Mix. Apply with a camel’s-hair pencil.
When the application dries thoroughly, go over it with a layer of traumaticine. This application will loosen itself in several days, when the process should be repeated.
IV.—When the skin is only slightly discolored use a pomade of salicylic acid, or apply the following:
| Acid chrysophanic, from | 1 to 4 parts |
| Acid salicylic | 1 to 2 parts |
| Collodion | 40 parts |
V.—When there is need for a more complicated treatment, the following is used:
| (a) | Corrosive sublimate | 1 part |
|---|---|---|
| Orange-flower water | 7,500 parts | |
| Acid, hydrochloric, dilute | 500 parts | |
| (b) | Bitter almonds | 4,500 parts |
| Glycerine | 2,500 parts | |
| Orange-flower water | 25,000 parts |
Rub up to an emulsion in a porcelain capsule. Filter and add, drop by drop, and under constant stirring, 5 grams of tincture of benzoin. Finally mix the two solutions, adding the second to the first.
This preparation is applied with a sponge, on retiring, to the affected places, and allowed to dry on.
