Add the acids, ethers, etc., to the alcohol, and finally add the water. Let stand several days, and, if necessary, filter.
III.—The Berlin Apothecaries have adopted the following as a magistral formula:
| Aromatic tincture | 4 parts |
| Spirit of nitrous ether | 5 parts |
| Alcohol, 90 per cent | 1,000 parts |
| Distilled water, quantity sufficient to make | 2,000 parts |
Mix the tincture and ether with the alcohol, add the water and for every ounce add one drop of tincture of rhatany.
Of these formulas the first is to be preferred as a close imitation of the taste of the genuine article. To imitate the color use burnt sugar.
Liqueurs.
Many are familiar with the properties of liqueurs but believe them to be very complex and even mysterious compounds. This is, of course, due to the fact that the formulas are of foreign origin and many of them have been kept more or less secret for some time. Owing to the peculiar combination of the bouquet oils and flavors, it is impossible to make accurate analyses of them. But by the use of formulas now given, these products seem to be very nearly duplicated.
It is necessary to use the best sugar and oils obtainable in the preparation of the liqueurs. As there are so many grades of essential oils on the market, it is difficult to obtain the best indirectly. The value of the cordials is enhanced by the richness and odor and flavor of the oils, so only the best qualities should be used.
For filtering, flannel or felt is valuable. Flannel is cheaper and more easily washed. It is necessary to return filtrate several times with any of the filtering media.
As a clarifying agent talcum allowed to stand several days acts well. These rules are common to all. {769}
