The writer says aristol should not be used in the form of an ointment but should be applied directly to the wound. It is insoluble in water, but forms a tough brown pap with olive oil, which is, however, difficult of application. The undissolved powder itself is inert. Therefore, the ulcer should be strewn with powder, and a drop of olive oil be allowed to fall slowly from a glass rod upon it. Without waiting for the solution to be effected, the ulcer is promptly covered with some fine impermeable tissue, under which the solution takes place slowly. No cotton or charpie should be applied to the ulcer. If the secretions are very profuse, or if the ulcer is in an unfavorable location, this dressing must be secured by means of court plaster. The application should be renewed twice daily, after careful removal ofthat previously applied. Its advantages are that it is painless, odorless and non-irritating, and that there are no inconveniences attaching to its use. Painful ulcers become painless, and previously bedridden patients become able to go about after its use. If, however, as is the case in corroding or torpid ulcers, the healing tendency is not sufficiently rapid, recourse to iodoform must be had.
Although aristol is not curative in soft chancres, nevertheless, where it is substituted for iodoform, there is no danger that the lesions will assume a more serious character. This happens frequently when mercurial ointments are used. In hard chancres its action is better. But it is of especial value in secondary lesions, in ulcerating gummata, in tubercular syphilides, etc. Although if continued long enough, this treatment will effect a cure, nevertheless it is hastened by the internal administration of anti-syphilitics.
