have added Aqua ammonia, which is contained in several of 
the recipes in the table, and is an excellent addition; and have 
substituted for the oil of Origanum the essential oil of the Mo- 
nar da punctata a native plant nearly resembling it in odor, 
though more stimulating, and more readily to be procured 
genuine. In preparing this tincture, it is necessary to use 
soaps made with animal fats, if we wish the preparation to 
remain solid. The soaps made with vegetable oils, form so- 
lutions in alcohol that remain liquid at the common tempera- 
ture.

Dissolve the soap in the alcohol with a gentle heat, add the 
remaining articles, suffer the impurities to subside, and pour 
off into vials while warm. 
8. British Oil. 
For the preparation of this patent medicine, there are in 
use two distinct classes of recipes, one having oil of turpen- 
tine and the other flaxseed oil or spermaceti oil as the basis. 
The character of the medicine as exhibited in the directions, 
and the uses to which it is now applied, would seem to require 
a preparation selected from both classes. With this view the 
following formula is adopted; omitting the oil of bricks, a nau- 
seous and unskilful preparation, which has long been banished 
from the pharmacopoeias, although contained in most of the 
recipes, and introducing Seneca oil in its place. As there ap- 
pears to be no good reason for retaining it, the spermaceti oil 
is also rejected.
