MR. YOUNGER’s (OLD-STREET) for @ 
METHOD of extradling WORTS from 
MALT, BARLEY, and other GRAIN 
a@nd SUBSTANCES. 
Mr. Younger’s invention may be thus 
defcribed: :—the veffel in which the ingre- 
dients are put, from which the worts are 
to be extraéted, is to be guarded from 
the immediate ation of the fire by which 
it is to be heated; and the proper degree 
of heat is to be communicated to it by 
boiling water, or any other liquid, which 
will-receive.and communicate the fame de- 
gree.of zheat as water againft the bottom, 
fides, or other parts of the veflel in which 
the ingredients are put. Let the cauldron 
or boiler, in which the fubftance is to be 
put, be immerfed in another boiler con- 
tainmg water, and heated bya fire or fur- 
nace. As this part of the apparatus has 
no claim to novelty, Mr. Younger has 
not given any particular deferistion of it, 
and of courfe lays no claim to any exclu- 
five privilege to it. The inner boiler ts 
to be fixed at a convenient diftance (fay 
fix inches, if for two quarters of malt, 
&c.) from the bottom and fides of the 
outer one, and the two fhould ‘be joined 
together at or near the tops. A cock 
may be made to pa{s from the inner boiler 
quite through the outer one. In the in- 
ner one, which ferves as a mafh-tub, a 
falfe bottom is advantageous, as are alfo 
agitators or ftirrers, which may be work- 
ed either by machinery or hand. After 
the grain is bruifed, it is to be intreduced 
into the inner veffel, and a proper quan- 
tity of cold water added, viz. about feven 
or eight barrels of water to four quarters 
of malt. After the materials have been 
fuffered to macerate, the outer boiler is 
then to be filled with water, and a very 
ftrong fire applied. "The contents of the 
inner boiler fhoujd occafionally be ftirred, 
and after the firft extract is drawn off, 
more water, at a heat alittle below the 
boiling point, is to be introduced for the 
purpole of making up the length, or the 
quantity of worts. By this method the 
faccharine and other foluble matter is 
more effectually extracted from the malt, 
' &c., the extract is obained free from ‘aci- 
dity, and the beer will’ be much better 
than that made from worts, prepared in 
the ufual manner. Worts may be extraét- 
ed in the fame way for the malt diftillery, 
and for making vinegar. ee 
Obfervations by the patentee.—lIt is an 
advantage in this mode of mafhing, that 
the pores of the grain are fo completely

opened. by the maceration in cold water’, 
that ona quick application of heat, every 
particle of the faccharine matter may be ex- 
traéted, and nothing left but the mere husks. 
The quantity of coals ufed in this mode of 
operation is not greater-than is confumed 
in the common way. Malt newly taken 
from the kiln, will not yield fo much or 
fo good wort, as that which has been 
for fome time expoféd to the atmofphere 
of the granary: the reafon oi which iS, 
according to the patentee, that the. for- 
mer poffeffes no moifture, which acts as a 
conductor for the hot liquor ; but the lat- 
ter being mellowed by time, and having 
imbibed the moifture-of the atmoiphere, 
oppofes lefs refiftance to the introduction 
of the water into the particles of which 
the math is compofed. 
We are difpofed to think that the ad- 
vantages Mr. Younger imputes .to the 
mere moifture of the atmofphere, fhould 
rather be referred to the oxygen of the 
atmofphere. 
The extra&, when properly managed, 
is fo ftrong in the firf mafh, that a fecond 
completely exhaufts the ftrength of the 
grain, by which the expence of a third 
math is faved ; and Mr. Younger afferts 
that, from comparative experiments care- 
fully made, this mode of ‘mafhing exceeds 
that obtained by the ulual procefs by at 
leaft 20 per cent.

MR. FRANCIS GODBOLD’S (WESTMIN- 
STER) for an AMPROVEMENT ia the 
MANUFACTURE Of DICE. 
The dice are made in the ufual form, 
and the difference between thole of Mr. 
Godbold’s and, thofe in common ufe is, 
that in?ead of niaking holes in them, 
and filling the holes with a coloured fud- 
ftance, he recommends the drilling or 
punching {mall circles, and filling the cavi- 
ties of the circle with a coloured fubftance.

to the movements as to aét with the

enabled to write feveral copies of a letter,

the ufual trouble of writing one letter, 
They have already been conftructed with 
two, three, and five pens, and more, if ne- 
ceflary, might be managed. The utility 
of this machine is obvious in all cafes de-
