the invention upon which Mr. Tickell 
founds his claim for exclufive privileges. 
Te is by the application of fteam in various 
ways, that the vegetable and animal mat- 
ters are fooner diflolved, and their virtues 
or properties more efreétually extracted, 
than can be done by the ufual method. 
M. ANTHONY C#ESARI DE POGGI's (of 
NEW BOND-STREET) for IMPROVE- 
MENTS iz the confiruciing and ufing of 
ORDNANCE, io be employed both in SEA 
ezd LAND-SERVICE: 
The objeéts intended to be anfwered by 
this invention are, to produce a rapid fire, 
and to fecure the men. 
‘The improved gun is conftructed from a 
Calibre fcale as ufual ; but the trunnions 
are nearly in the axis of the piece, and no 
more increafe of weight is left behind 
them, than what is fuifcient to caufe the 
breech to preponderate, and the piece to 
be fteady on the prop that fupports it 
behind at the moment of fire, and to de- 
fcend when that fupport is withdrawn. 
(Here follows a particular account of the 
feveral additions to the old conftruétion of the 
gun.) 
To regulate the elevationand depreffion 
of the gun, fome machinery is fixed, con- 
fitting of a fpindle, with pinions acting on 
two wheels, between which is a cylindrical 
barrel, and on this two double and fingle 
‘flat linked chains wind their ends, extend- 
ing to the lower part of a fixed box, where 
two eye-bolts are fixed, and an iron pin 
‘runs through them, which is kept in by a 
mut, and the chain is kept clofer at that 
end to enable it to wind without riding. 
‘The gun by this means is capable of be- 
ing elevated or deprefled by the turning of 
awinch. By putting a catch-bolt back, 
the breech of the gun falls down on the 
axletree, and the charge being previoufly 
jaid in the bore, immediately runs home. 
‘The gua is brought up by cords in an in- 
‘ftant, and as fpeedily laid to the object by 
the machinery and contrivance of the car- 
‘riage; by which means a rapid and de- 
fiructive fire may be kept up, without ex- 
pofing the men who load ts the leaft dan- 
ger irf the operation, 
Other contrivances for elevating and de- 
prefiing the piece are intended to be intro- 
duced ; and all guits on the new conftruc- 
tion may, if in any cafe it fhould be 
thought more adyifeable, be loaded and 
fixed in the ufual manner, fince the pieces 
and their carriages are not, by thefe im- 
provements, rendered in the leaft unfit for 
2 
the mode of manocuyreing now ufed,

This fpecification contains alfo fullde-

of the fiding-carriage, conftructed to ad-

open angle with the fhip’s fide; and of an

MR. THOMAS MALTBY’S (NOTTING= 
HAM) for @ STIRRUP. 
his invention is intended to preferve 
the rider from the accidents occafioned by 
the foot hanging in the ftirrup, thould he 
be thrown from his feat. 
The bottom of Mr. Maltby’s fuirrup Is 
made larger than the !ower furface of the 
foot, and may be plain, or in bars, accord- 
ing to the fancy of the workman. From 
the middle of the fides a hoop fprings, 
very much like the hoop of the common 
ftirrup ; then at fmall difiances from each 
other, allround the front part of the ftir- 
rup, bended bars are faftened, and being 
carried up, unite in the center-hoop, and 
thus make a fort of bafket-work for the 
front part of the foot ; the bars are placed, 
too clofe to admit the boot or fhoe, and 
therefore the poffibility of entangling the 
foot is effectually. prevented, fhould the 
rider be thrown from his horfe; and the 
whole is fo contrived, by sg tas the 
ftirrup to the particular perfon for whom 
it is made, that the inftep and ankle can 
never be injured by fri€tion. ‘The whole 
may be made of iron, or any other metal 
fit tor the purpofe. 
Obfervation.—We have not feen one of 
thefe ftirrups executed 5 but, from the 
drawing which accompanies the fpecifi- 
cation, it fhould appear not an orna- 
ment ; if, however, fecurity is attained, 
the public will doubtlefs confider the invene 
tion as worthy of being adopted.

louring, and uniting the sKiNs of SHEEP. 
and LAMBS. re, 
The fpecification of this patent contains 
particular and minute direftions for the 
whole procefs of tanning and colouring 
fkins, from the time they are taken from 
the animal till they are in a finithed ftate. 
Mr. Richardfon fhews in what manner. 
they may be made to refemble any animal, 
either by {potting the fkins, or by differ- 
ent kinds of fhading. ‘The manner which 
he adopts as the moft preferable, for unit- 
ing the fkins, is by cutting the’ feveral 
pieces to the fame length, and then by

lapping
