vanilla, eleven grains;
rose-wood, half a drachm; rose-pink, eight drachms. All to be finely
powdered and mixed.

1691. Quinine Tooth Powder.

Rose pink, two drachms; precipitated chalk, twelve drachms; carbonate
of magnesia, one drachm; quinine (sulphate), six grains. All to be
well mixed together.

1692 Hair Dye.

To make good hair dye some lime must be first obtained, and reduced to
powder by throwing a little water upon it. The lime must then be mixed
with litharge in the proportion of three parts of lime to one of
litharge. This mixture, when sifted through a fine hair sieve, forms
the most effectual hair dye that has yet been discovered.

1693. Directions for Application.

Put a quantity of the mixture in a saucer, pour boiling water upon it,
and mix it up with a knife like thick mustard; divide the hair into
thin layers with a comb, and plaster the mixture thickly into the
layers to the roots, and all over the hair. When it is completely
covered with it, lay over it a covering of damp blue or brown paper,
then bind over it, closely, a hankerchief, then put on a night-cap,
over all, and go to bed; in the morning brush out the powder, wash
thoroughly with soap and warm water, then dry, curl, oil, &c. Hair
thus managed will be a permanent and beautiful black.

1694. Hair Dye, usually styled Colombian, Argentine, &c., &c.

Solution No. i., Hydrosulphuret of ammonia, one ounce; solution of
potash, three drachms; distilled or rain water, one ounce (all by
measure). Mix, and put into small bottles, labelling it No. i.

Solution No. ii. Nitrate of silver, one drachm; distilled or rain
water, two ounces. Dissolve and label No. ii.

1695. Directions for Application.

The solution No. i. is first applied to the hair with a tooth brush,
and the application continued for fifteen or twenty minutes. The
solution No. ii. is then brushed over, a comb being used to separate
the hairs, and allow the liquid to come in contact with every part.
Care must be taken that the liquid does not touch the skin, as the
solution No. ii. produces a permanent dark stain on all substances
with which it comes in contact. If the shade is not sufficiently deep,
the operation may be repeated. The hair should be cleansed from
grease before using the dye.

1696. To test Hair Dye.

To try the effect of hair dye upon hair of any colour, cut off a loc
