in a mill and sifts them as often as the 
process is found profitable. For the 
purpose of sifting, he uses a frame, about 
6 or 7 feet long, two feet wide, and 5 
inches deep, into which is fixed another 
frame or frames, with silk bottoins, 
through this by means of 1a velocity ob- 
tained by mechanical contrivances, the 
mustard is passed. The sieve is. to be 
supplied by a hopper, placed above it, 
and to this Mr, Shotwell lays an exclu- 
sive claim. The sieve should be so 
hung that it may conveniently be brush- 
ed under the bottom, or brushes may be 
fixed the length of the sieve, to be mo- 
ved by crank, by machinery, or any other 
way at pleasure. 
Observations. — The advantages de- 
scribed as belonging to this invention are, 
1. That a considerable quantity of 
genuine mustard is obtained from offal, 
hitherto deemed of little value. 2. An 
article possessing a considerable degree 
of pungency, is obtained froin the brown 
mustard-seed, at a small expence. 3. 
By connecting a hopper or other appa- 
ratus, with the upper end of the sieve, 
the labour of supplying the sieve with 
meal is very much lessened, and the sup- 
ply is more regular than when done by 
the hand ;and by fixing long brushes under 
the sieve, the labour of brushingis much 
lessened.

4uR EDWARD DAMPIERS (PRIMROSE- 
STREET, LONDON,) for Machinery for 
reducing Drugs, &c. into fine Powder. 
This machinery consists of a large 
wheel or fiat surface, of iron or other 
metal, fixed toa vertical shaft or arbor, 
to be driven round by the powers com- 
monly used im manufactures. Upon 
the face of the wheel, I attach, by screws, 
keys, bolts, &c. certain cutters or raspers, 
with their edges or faces toothed and di- 
rected upwards; each of which is fixed | 
so that its length shall be directed to- 
wards the shaft, either precisely, with 
such an obliquity, as that the line, of the 
length of each rasper, shall every where 
cross the circles described by the motion 
of its teeth; and close to each cutter or 
rasper, there is a perforation, or long 
hole, quite through the face of the wheel, 
for the purpose of perimitting the rasped 
wood or other material to fall through. 
In the use and application, of this mach- 
nery, the drugs, &c. are placed and secu- 
red upon the face of the said wheel, 
which by its rotation causes the teeth of 
the cutters to act upon the same, and 
to cut off portions ar raspings off the 
samme, which fall through into a proper

receptacle. The wheel may be bevelled 
inwards, or outwards, and, admits of va- 
rious forms, dimensions, and velocities ; 
and by various contrivances, all the cut~ 
ters may be fixed upon the wheel at 
once, or a part of them may be sepa- 
rately attached, and taken out wher 
needful, ‘The drawings attached to this

MR. JOSEPH CUFE’S (WHITECHAPEL,} 
Sor anew Method of sluughtering Cat- 
tle, &c. 
The title of this specification mentions 
cattle of divers descriptions, from oxen, 
downwards, but the drawings are con- 
fined to hogs. We have carefully ex- 
amined the specification ; and from that 
and the included drawings, we understand 
that Mr, Cuff keeps the animals to be 
killed in a certain kind of pen in the 
slaughter-house, and that two persons 
are employed in the business, or perhaps 
three; the occupation of one person, is 
to catch the beast, or by some other ma- 
neeuvre to fasten a rope or hook, on one 
or both of its hind legs; another persoa 
is then by means of a wheel and pulley, 
or other apparatus, to draw the animal 
up to a certain height, and a third person 
is to fix the rope on the tenter hooks, 
and while thus suspended with its head 
downwards, the animal’s throat is to be. 
cut. ; 
Remark,—The Patentee professes that 
the meat is better by this mode of slaugh= 
tering, than by the usual methods. We 
must, however, observe, that, if its suppo- 
sed advantages arise from the mere posi- 
tion of the animal when killed, the in- 
vention is not new; it has been practi- 
sed ina village within a mule north of 
London, some years. Nor do we see 
that there can be any novelty in the ap-. 
paratus for dragging up the animal and 
suspending it by its hind legs, so as to 
warrant an exclusive clain. We are, 
from a view of the invention, induced to 
believe that the method will, in practice, 
be found mach more cruel, than that 
usually adopted; and therefore cannot 
merit the applause and patronage of the 
public, who should endeavour, to miti- 
gate the sufferings of creatures whose 
lives are sacrificed to supply their wants.
