«Cologne Spirits or Deodorized Alcohol.»—This is used in all toilet

preparations and perfumes. It is made thus:

Alcohol, 95 per cent 1 gallon

Powdered unslaked lime 4 drachms

Powdered alum 2 drachms

Spirit of nitrous ether 1 drachm

Mix the lime and alum, and add them to the alcohol, shaking the mixture

well together; then add the sweet spirit of niter and set aside for 7

days, shaking occasionally; finally filter.

Oil of neroli 1⁠/⁠2 fluidrachm

Oil of lemon 1 fluidounce

Essence of jasmine 6 fluidounces

Essence of musk 2 fluidounces

Rose water 1 pint

Alcohol 8 pints

Mix, and if cloudy, filter through magnesium carbonate.

«Lavender Water.»—This, the most famous of all the perfumed waters, was

originally a distillate from a mixture of spirit and lavender flowers.

This was the perfume. Then came a compound water, or “palsy water,”

which was intended strictly for use as a medicine, but sometimes

containing ambergris and musk, as well as red sanders wood. Only the

odor of the old compound remains to us as a perfume, and this is the

odor which all perfume compounders endeavor to hit. The most important

precaution in making lavender water is to use well-matured oil of

lavender. Some who take pride in this perfume use no oil which is less

than 5 years old, and which has had 1 ounce of rectified spirit added

to each pound of oil before being set aside to mature. After mixing,

the perfume should stand for at least a month before filtering through

gray filtering paper. This may be taken as a general instruction:

Artificial Violet.—Ionone is an artificial perfume which smells

exactly like fresh violets, and is therefore an extremely important

product. Although before it was discovered compositions were known

which gave fair imitations of the violet perfume, they were wanting in

the characteristic tang which distinguishes all violet preparations.

Ionone has even the curious property possessed by violets of losing its

scent occasionally for a short time. It occasionally happens that an

observer, on taking the stopper out of a bottle of ionone, perceives no

special odor, but a few seconds after the stopper has been put back in

the bottle, the whole room begins to smell of fresh violets. It seems

to be a question of dilution. It is impossible, however, to make a

usable extract by mere dilution of a 10 per cent solution of ionone.

It is advisable to make these preparations in somewhat large

quantities, say 30 to 50 pounds at a time. This enables them to be

stocked for some time, whereby they improve greatly. When all the

ingredients are mixed, 10 days or a fortnight, with frequent shakings,

should elapse before filtration. The filtered product must be kept in

well-filled and well-corked bottles in a dry, dark, cool place, such as

a well-ventilated cellar. After 5 or 6 weeks the preparation is ready

for use.

TOILET WATERS.

Toilet waters proper are perfumed liquids designed more especially

as refreshing applications to the person—accessories to the bath

and to the operations of the barber. They are used sparingly on the

handkerchief also, but should not be of so persistent a character as

the “extracts” commonly used for that purpose, as they would then be

unsuitable as lotions.

Ammonia Water.—Fill a 6-ounce ground glass stoppered bottle with a

rather wide mouth with pieces of ammonium carbonate as large as a

marble, then drop in the following essential oils:

Oil of lavender 30 drops

Oil of cinnamon 10 drops

Oil of clove 10 drops

Finally fill the bottle with stronger water of ammonia, put in the

stopper and let stand overnight.

soft soap, 20 parts; glycerine, 15 parts; essential oil of birch buds,

sufficient to tint. Mix the water with an equal volume of spirit and

dissolve the soap in the mixture. Mix the oil and other ingredients

with the remainder of the spirit, add the soap solution gradually,

agitate well, allow to stand for 8 days and filter. For use, dilute

with an equal volume of water.

«The Preparation of Emulsions of Crude Petroleum.»—Kerosene has long

been recognized as a most efficient insecticide, but its irritating

action, as well as the very considerable cost involved, has prevented

the use of the pure oil as a local application in the various parasitic

skin diseases of animals.

In order to overcome these objections various expedients have been

resorted to, all of which have for their object the dilution or

emulsification of the kerosene. Probably the best known and most

generally employed method for accomplishing this result is that which

is based upon the use of soap as an emulsifying agent. The formula

which is used almost universally for making the kerosene soap emulsion

is as follows:

Kerosene 2 gallons

Water 1 gallon

Hard soap 1⁠/⁠2 pound

The soap is dissolved in the water with the aid of heat, and while this

solution is still hot the kerosene is added and the whole agitated

vigorously. The smooth white mixture which is obtained in this way is

diluted before use with sufficient water to make a total volume of 20

gallons, and is usually applied to the skin of animals or to trees or

other plants by means of a spray pump. This method of application is

used because the diluted emulsion separates quite rapidly, and some

mechanical device, such as a self-mixing spray pump, is required to

keep the oil in suspension.

It will be readily understood that this emulsion would not be well

adapted either for use as a dip or for application by hand, for in the

one case the oil, which rapidly rises to the surface, would adhere to

the animals when they emerged from the dipping tank and the irritating

effect would be scarcely less than that produced by the plain oil, and

in the second case the same separation of the kerosene would take place

and necessarily result in an uneven distribution of the oil on the

bodies of the animals which were being treated.

Within recent years it has been found that a certain crude petroleum

from the Beaumont oil fields is quite effective for destroying the

Texas fever cattle ticks. This crude petroleum contains from 40 to 50

per cent of oils boiling below 300° C. (572° F.), and from 1 to 1.5 per

cent of sulphur. After a number of trials of different combinations of

crude oil, soap, and water, the following formula was decided upon as

the one best suited to the uses in view:

Crude petroleum 2 gallons

Water 1⁠/⁠2 gallon

Hard soap 1⁠/⁠2 pound

Dissolve the soap in the water with the aid of heat; to this solution

add the crude petroleum, mix with a spray pump or shake vigorously, and

dilute with the desired amount of water. Soft water should, of course,

be used. Various forms of hard and soft soaps have been tried, but soap

with an amount of free alkali equivalent to 0.9 per cent of sodium

hydroxide gives the best emulsion. All the ordinary laundry soaps are

quite satisfactory, but toilet soaps in the main are not suitable.

An emulsion of crude petroleum made according to this modified formula

remains fluid and can be easily poured; it will stand indefinitely

without any tendency toward a separation of the oil and water and can

be diluted in any proportion with cold soft water. After sufficient

dilution to produce a 10 per cent emulsion, a number of hours are

required for all the oil to rise to the surface, but if the mixture is

agitated occasionally, no separation takes place. After long standing

the oil separates in the form of a creamlike layer which is easily

mixed with the water again by stirring. It is therefore evident that

for producing an emulsion which will hold the oil in suspension after

dilution, the modified formula meets the desired requirements.

In preparing this emulsion for use in the field, a large spray pump

capable of mixing 25 gallons may be used with perfect success.
