giving the ftroke or cut. Thefe fevera 
parts are fupparted by, or attached toa 
frame or platform of folid and fecure 
workmanihip, either of wood or metal, or 
both, according to the nature of the work 
intended to be performed. 
Thefe various parts are all defcribed in 
the fpecification with great precifion and 
minutenefs, and the general action of the 
machinery is reprefented in the following 
manner. 1/ The file being prepared as 
ofual for cutting, muft be fixed in the 
clip of the carriage, and the fliding block 
brought up and fixed to fteady its other 
extremity. 2. The nut of the {crewbeing 
then opened, the carriage is flided to its 
place, fo that the chizei may be fitwated 
over that part of the file which is to re- 
ceive the firft ftroke.. 3. The nut is then 
clofed, and the {mall roller of the prefing 
lever, is made to bear upon the face of 
the file. 4. The firft mover being put 
into aStion, raifes, and lets fall the appa- 
ratus, for giving the ftroke by which the 
file receives acut. 5. The regulating- 
gear moves the carriage, and conlequently: 
the file through a determinate {pace. 
6. The cut is then given, and in this 
manner the file becomes cut throughout. 
7. The file is then taken out, and cut on 
the other fide. 8. The bar is then taken 
off or not, according to the pleafure of 
the artift, and the crofs ftrokes are given 
over the furfaces as before. The faid ma-.

and by the difpofition of the chizels, and

MR. JOSEPH DE OLIVEIRAS BARRETO 
(OLD BURLINGTON-STREET) for @ 
METHOD of curing RUPTURES. 
This method confiits of an ointment or 
falve,compofed of ane pound of incenfe, pal- 
verized, one pound of almecago, 245 pound 
of turpentine, one pound of balfam of capivi, 
and ene pound and a quarter of white or 
virgin wax. ‘Thefe materials are to be 
repeatedly ftirred together for thef{pace of 
three days, then te be heated over the fire 
till well melted, afterwards to be left for 
eight days, then heated again, and when 
cold it wail be fit for ufe. 
The ointment is to be fpread on Jeather, 
and applied exaétly over the rupture, 
over which is to be placed a ftrong trufs ; 
the patient to lie in bed twenty-four hours. 
For fifteen days the plafter is to remain, 
and thena new one is to be put on with the 
fame-care, and continued ter fifteen more 
days, when the cure is completed,

Obfervation. Knowing the nature of 
rupturous complaints, we muft be allowed 
to hefitate-in believing, that the limited 
period of thirty days is fufficient te 
work a cure in almoft any cafe. Nor in=- | 
deed do we give a great deal more credit 
to the efficacy of the drugs of which the 
cintment is compounded. When the pas 
tient is young , the trufs applied ‘with fxill, 
and the ujuak & cercife #s mederate, a cure 
may be expected without the application 
of ointment ;. but we fear that in all cafes 
it muft be a warke of time, and we advife 
ee fon who has found a trufs neceffary, 
to leave it off at the end of thirty days, 
although he fhall, during that period, have 
made ule of Mr. Barretto’s ointment.

MR. JOHN BARNETT’S (BIRMINGHAM) 
Jor a new and improved method of 
making PARASOLS amd UMBRELLAS;, 
According to the common mode of 
conffruéting parafols and umbrellas, alt 
the ftretchers are fixed toone ferrule, fo 
that none can be extended or relaxed with- 
out extending or relaxing the whole at 
once. Mr. Barnett has invented a plan 
by which any number of the ftretchers 
may be made ufe of at pleafure, and con- 
fequently the fame inflrument may be made 
‘to aflume various fhapes, and mays in 
fa&t, be applied to different purpofes. Ar- 
parafo] thus conftrudied, he calls a para- 
fout ; and it may be afi to defend the fair 
poffeffor of ir, not only from the {corch- 
ing fun, or the driving rain, but it will 
as readily be converted into a fire-icreen, 
or a fhade for a candle, &c.

upcn an improved confirudiien. 
This gentleman propoles to attain, by 
his invention, feveral: important objects : 
fuch as the prevention of the external air 
in rooms, where warmth is required ; the 
prevention of dirt, duft, &c. fo trouble=-_ 
fome in moft grates ; the prevention of all 
fmells and effluvia occafioned by foot ; 
and even the prevention of the dry-rot, in 
thofe rooms and houfes, where his grates 
are made ufe of. ‘This grate, like others 
which we have feen, turns on a pivot, fo 
that the front or back of dt may at plea- 
fure be turned towards the room ; there 
are Contrivances belonging to it to prevent 
accidents by fire; anda grating made, in 
form of an inclined plane, behind and juft 
above it; the cinders being thrown upon 
this, will of courfe part with the duf inte
