When the skin is as yet unbroken, Hugo Kuhl advises the following:

I

Carbolized water. .. 4 drachms

Nitric acid......... 1 drop

Oil of geranium .... 1 drop Mix. Pencil over the skin and then hold the penciled place near the fire until the skin is quite dry.

If the skin is already broken, use the following ointment:

II

Hebra's ointment.. 500 parts

Glycerine......... 100 parts

Liquefied carbolic

acid........... 15 parts

Mix. Apply to the broken skin occasionally.

III

Camphor.........     25 parts

Iodine, pure......     50 parts

Olive oil..........   500 parts

Paraffine, solid....   450 parts Alcohol, enough.

Dissolve the camphor in the oil and the iodine in the least possible amount of alcohol. Melt the paraffine and add the mixed solutions. When homogeneous pour into suitable molds. Wrap the pencils in paraffine paper or tin foil, and pack in wooden boxes. By using more or less olive oil the pencils may be made of any desired consistency.

Dissolve 5 parts of camphor in a mixture consisting of 5 parts of ether and 5 parts of alcohol; then add collodion sufficient to make 100 parts.
