FREEZING PREVENTIVES
Liquid For Cooling Automobile Engines.
A practical manufacturing chemist of wide experience gives this:
A saturated solution of common salt is one of the best things to use. It does not affect the metal of the engine, as many other salts would, and is easily renewed. It will remain fluid down to 0° F., or a little below.
Equal parts of glycerine and water is also good, and has the advantage that it will not crystallize in the chambers, or evaporate readily. It is the most convenient solution to use on this account, and may repay the increased cost over brine, in the comfort of its use. It needs only the occasional addition of a little water to make it last all winter and leave the machinery clean when it is drawn off. With brine an incrustation of salt as the water evaporates is bound to occur which reduces the efficiency of the solution until it is removed. Water frequently must be added to keep the original volume, and to hold the salt in solution. A solution of calcium chloride is less troublesome so far as crystallizing is concerned, but is said to have a tendency to corrode the metals.

When the skin is as yet unbroken, Hugo Kuhl advises the following: {364}
| 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.
IV.—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.
V.—Dissolve 1 part of thymol in 5 parts of a mixture of ether and alcohol, then add collodion sufficient to make 100 parts.
| VI.— | Carbolic acid | 2 parts |
|---|---|---|
| Lead ointment | 40 parts | |
| Lanolin | 40 parts | |
| Olive oil | 20 parts | |
| Lavender oil | 1 1/2 parts | |
| VII.— | Tannic acid | 15 parts |
| Lycopodium | 15 parts | |
| Lard | 30 parts | |
| VIII.— | Zinc oxide | 15 parts |
| Glycerine | 45 parts | |
| Lanolin | 40 parts | |
| IX.— | Ichthyol | 10 parts |
| Resorcin | 10 parts | |
| Tannic acid | 10 parts | |
| Distilled water | 50 parts |
Any of these is to be applied about twice a day.
