On Monday, the 19th ult. Mr. Carlisle 
enmmenced. his course of anatomical 
lectures at the Royal Academy, which 
shall be noticed in our next; .as shall be 
the Rev. Mr. Foster’s new Number of 
his elegant selection from the works of 
the best masters; and we are glad to see 
Patents lately Enrolled 
[Dec. 4, 
that he has included Sir Joshua Reys

MR. MICHAEL SHANNON’S,. (BERWICK- 
STREET, LONDON,) for Improvements 
an the Art of Brewing. 
1‘ the specification, giving an account 
of these improvements, we have out- 
Iined drawings exhibiting representations 
of the machinery, seen on different sides. 
From the lower part of the copper is a 
communication, through a cock and pipe, 
into a box or chamber from which there 
are five communications, viz. one through 
acock to empty it; another to the bottom 
of the infusing vessel to draw off the con- 
tents ; another to the top of the infusing 
vessel ; one with a pump, worked by the 
first mover; and another with the air 
vessel, which keeps up a constant re-action 
when required. The infusing vessel may 
be made of different forms and inaterials, 
but itis recommended, by way of prever- 
ence, that it should be cylindrical, and of 
wood, and it is to be provided with two 
false bottoms, or perforated partitions, 
one near each extremity, for the purpose 
of allowing the liquor or wort to pass 
more freely into and out of the same, 
during the time of operating, The pro- 
eess is described as follows: Malt is put 
into the infusing vessel, which in must 
eases may be filled, or nearly filled, with 
the same, excepting between the false 
beitoms or perforated partitions and the 
end thereof, and the water is.to be put in 
due quantity into the boiler, and heat ap- 
F3 as usual. When the water is suth- 
ciently hot, it is to be so ¢ app! lied by means 
oF the: cocks and pipes above described, 
that it will rise through the malt to the 
level in the boiler ; but it would not pass 
through if it were not for the pump, which 
is, at the same time, to be worked by any 
adequate and convenient first mover, 
and it draws the water through a lower 
valve; and, at its returning stroke, forces 
it thro ugh an upper valve, placed within 
the receptacle on.each end of the barrel. 
By this action: the hot water 7. forced 
gradually through the malt in a constant 
_ stream, the air escaping through a pipe, 
“which returns through the boiler by means 
of the cock and pipe, and by this means 
the wort is kept hot, and repeatedly pase 
sed through the grain until the strength 
of the malt is entirely extracted. , And 
whenever it may be found necessary and 
expedient to cause the water, liquor, or 
wort, to pass down the infusing vessel 
instead of upwards, it will then be only 
necessary that one set of cocks should be 
shut, and another set opened, and in that 
situation the heated water will be forced 
up the pipe, and downwards through the 
vessel; out of which it will pass mto the 
boiler, by a reverse operation; in this 
case, it will be needful to keep the cock 
shut, until the infusing vessel is filled with 
liquor. By. these improvements, « the 
wort may be made as strong as the pro» 
portions of materials will allow; the in« 
convenient and. imperfect operation of 
mashing is avoided, and the sprout, or 
exhausted. grain, may. be. afterwards 
drawn out with great facility and saving 
of labour. A like apparatus may be 
applied for passing the wort. through 
heps, instead of boiling, in case the saine 
should be preferred, either for purposes 
of economy, or giving a peculiar strength 
or difference of flavour to the fiquar by 
this method, 
MR. CHARLES WILLIAMS’S,(GRAVEL*LANB,

Malt, &c. G 
The machine, or mill, used on this oce 
casion, is composed of a ‘cylindrical or 
conical rol! ier, made of cast-iron, or any 
other metal, with grooves cut in ‘it in an 
oblique or parallel direction: this roller 
acts against loose knives, made of har- 
dened ‘steel, and screwed together so as 
to form the sane curve as the roller. 
These loose kuives, or cutters, may be 
taken out and ground, or sharpened, at 
pleasure. In the margin of Mr. Willie 
amiss, specification, is a drawing of the 
elevation of the mill... Vhe roller is put 
in motion by a steam-engine, or any other 
power; which roller acts against the 
knives or cutters; fixed in a parallel dis
