J. H. S. asks: "Will you kindly print formulas for preserving fresh ripe fruits? We desire to put the fruits in jars for display purposes and wish to use a solution that will effectively preserve the fruit and not change its color."

The following preservatives have been suggested by the U. S. Department of Agricul

ture:

1. Formaldehyde, 1 pound; water, 44 pounds; alcohol, 5 pints. Allow the mixture to stand, and should there be any sediment, pour off the clear liquid and add to it the remainder after filtering it through filter-paper.

2. Boric acid, 1 pound; water, 45 pounds. Dissolve by agitation, then add 5 pints of alcohol. If the fluid is not clear, allow to stand and settle, when the clear upper portion may be poured off and the remainder filtered.

3. Dissolve 1⁄2 pound of zinc chloride in 15 pounds of water. Agitate till dissolved, then add 1 2/3 pints of alcohol. Allow to stand until settled, then pour off the clear liquid and filter the remainder.

4. Sulphurous acid, 1 pint; water, 8 pints; alcohol, 1 pint. Allow the mixture to stand, and should there be any sediment pour off the clear liquor and filter the remainder.

The following is a list of fruits and the numbers indicate which preservative should be employed. Where two numbers are given either may be used, but the first is preferred:

Pears, green or yellow...

Select the finest specimens of fruit as to form and size. Handle carefully, and place in bottles, arranging them to show to best advantage. Fill each bottle to the neck with fruit, then pour on the liquid recommended, filling the bottles to within 1⁄2 inch of the stopper, so as to entirely cover the fruit. Then place the stopper in the bottle and run a little melted beeswax or paraffin over the joint to make it air-tight. Wrap the bottles in paper, to exclude the light, and preserve in a cellar or other cool place until required for shipment. Strawberries and raspberries should be cut from the plants or bushes with a pair of scissors, leaving a short piece of stem attached to each. Of course, fruits preserved in this manner should not be eaten.

Carbon in Automobile Cylinders.

A. N. writes: "Can you tell me the composition of a solution that will, when put in the cylinders of a gasoline engine, eliminate the

carbon?"

According to several garage owners with whom we have consulted, the formula for a

liquid preparation that will remove carbon effectually is as yet unannounced.

There are, however, a number of preparations on the market which are claimed to do the work but which upon examination or trial have proved unsatisfactory. Some of them, indeed, are evident frauds-for instance, those consisting essentially of gasoline or kerosene or of mixtures of the two. Another combination that is sold to a considerable extent is. said to be composed of a mixture of naphthalene dissolved in denatured alcohol. Mixtures of alcohol, gasoline, and ether have sometimes been recommended, but to employ such combinations is far from satisfactory.

If the carbon is firmly encrusted in the cylinders ordinary solvents have but little effect. The best way to accomplish the removal is by means of the so-called oxygen process. This method, however, is not practicable for the owner, but should be left to experienced repair men whose equipment is adequate for carrying on the work.

Provided the cleaning is done every ten days or two weeks, carbon may be removed to a certain extent by putting kerosene oil in the cylinders and allowing it to stand over night, starting the motor the next morning in the regular way. Such a frequent cleaning prevents the carbon from becoming deposited solidly and allows it to be removed by the solvent action of the kerosene. Some motorists content themselves by starting the motor and then pouring a little kerosene every minute or two through the air intake in the carbureter.

Syrup of Cinnamon and Tincture of Ferric Citrochloride.

S. M. writes: "Please state methods for the extemporaneous preparation of syrup of cinnamon and tincture of ferric citrochloride."

It is not practicable to make either one of these preparations extemporaneously. Both galenicals, however, are in quite frequent demand, and it should work no great hardship to keep a small amount of each one always on hand.

A passable substitute for syrup of cinnamon can be made by mixing a little spirit of cinnamon with syrup, but such a product is rather unsightly and should only be employed when the official syrup is unobtainable. Tincture of ferric citrochloride is not suited to extemporaneous preparations as, when freshly made, it contains an excess of saline matter that gradually settles out and which must be removed by filtration.

Working formulas for both preparations are to be found in the National Formulary, fourth edition.

Preserving Eggs.

V. W. E. asks: "What is the method followed in preserving eggs by the use of waterglass?"

For preserving eggs a solution of one part water-glass (silicate of soda) to nine parts of pure water is the most suitable one to use.

The silicate and water are mixed by merely

stirring them together with a wooden stick. The eggs may be packed in an earthen jar or in a wooden pail or cask provided with a cover. Sufficient liquid is then poured over them to cover the top layer of eggs with at least one inch of liquid. If preferred, the liquid may be poured into the jar first and the eggs dropped in a few at a time, as they are obtained. Under no conditions, however, should there be less than an inch of liquid covering the eggs, for the efficacy of the solution depends upon the exclusion of air.

It sometimes happens that the liquid, upon standing a while, assumes a semi-viscid, jellylike consistency. The eggs, however, will keep just as well in this mixture as in the more liquid medium. It is imperative to use only strictly fresh eggs, for those more than a week old are not likely to keep so well. Eggs preserved in silicate solution should be rinsed with water before they are used in order to remove all traces of the solution. If they are to be boiled in the shell a hole should first be pricked with a pin in the larger end, otherwise the egg will be likely to expand and break while boiling.

First sponge the hat with "A," then lay aside in a damp place, preferably a cellar, for a few hours; then apply "B," and put away again for 24 hours. Finally iron with a flat-iron which should not be too hot.

Sodium perborate has also been recommended for cleaning Panama hats. The steps in the process are: (1) Brush the hat in a solution of Castile soap in warm water to remove any superficial dirt, rinse, and (2) immerse for five minutes in a solution of hydrochloric acid in water containing 1⁄2 ounce of acid to the gallon; (3) transfer to a bath of sodium perborate-2 ounces to a gallon of lukewarm water-and allow to remain over

Questions of therapeutics are somewhat outside our province, but we are of the opinion that the continued use of copper sulphate, in susceptible cases, might give rise to symptoms of metallic poisoning. A color similar to that given by copper sulphate may be imparted to the mixture by using an oil-soluble color such as can be obtained from any large wholesaler or dealer in dyestuffs.

If you wish to market the preparation in tin boxes, we suggest that you lacquer the inside of the tins with flexible collodion. The question of perfume is almost entirely one of personal taste, and your selection of rose geranium oil will probably suit a considerable part of your

customers.

Concerning a Hair Preparation.

F. D. D. writes: "I have been marketing a scalp and hair oil the base of which consists of petrolatum with which has been incorporated a small amount of sulphur and copper sulphate. I have had no complaints concerning the product, but I would like to know whether or not the continued application of copper sulphate is harmful to the hair or scalp. If it is, what can I use in place of it to obtain the same color? I would also like to know if it would be safe to put the preparation in tin boxes and whether or not there would be any objection to the use of oil of rose geranium as a perfume.'
