272 Expeditious Mode of Manufacturing Vinegar. 
Art. X.—Expeditious Mode of Manufacturing Vinegar, practiced 
in Germany ; by Dr. Lewis Frucurwaneer, of New York. 
Turs method depends principally upon bringing the fluid, intend- 
ed to be converted into vinegar, into contact with the ferment and at- 
mospheric air, at a temperature of 100° F., in very thin layers, so 
that at the same time the menstruum may be deprived of its foreign 
matter, but not of any of its spirit and acid vapors. 
The annexed drawing of an apparatus for manufacturing any 
quantity of strong vinegar, within twenty four hours, shall now be 
explained. 
The principal part forms the concentrating tub A, resting on @ 
pedestal about 14/ or 2’ distant from the floor, which is 9 high, at 
the lower end 3’ and above 33’ in diameter, and provided with from 
seven to nine iron hoops. At the distance of 3” or 4” from the bot- 
tom there are some small holes c,c, 4” or 3 wide, and bored down- 
wards and covered with iron gauze, for permitting the air to enter- 
1” above the bottom the glass or tin tube g is fastened, through a 
cork, and is bent a little upwards, in order to keep the liquor in the 
cask constantly at a certain height, and to prevent the tube from 
being stopped up by swimming splinters or sediment; but the ori- 
fice must be at least 1” deeper than the holes c: this tube is to be 
connected with the recipient 6, for the ready vinegar. On two 
boards, fastened within the concentrator with wooden screws, 3
