NEW PATENTS LATELY ENROLLED. 
— ee Ee 
MR. MARCUS HYMAN’S (EXETER- 
STREET) for a COMPOSITION for 
SHAVING Without the USE of RAZOR, 
SOAP, oF WATER. 
HIS compofition is prepared and ufed 
in the following manner: mix one 
pint and a half of clear lime water, two 
ounces of gum-arabic, an half-ounce of 
ifinglafs, an eighth of an ounce of cochi- 
neal, a quarter of an ounce of turmeric- 
root in powder, an eighth of an ounce of 
falt of tartar, and an equal quantity of 
cream of tartar together; boil them for 
one hour at leat (ftirring up the mixture 
during the whole time of boiling, and 
being careful not to let it boil over), clear 
it through a fieve; then add two pounds 
and an half of iron pumice ftone finely 
pulverized ; mix the whole together into 
ene cake with the white of eggs. The 
cake fo made is to be divided into twelve 
{maller ones; dry them in the open air 
for three days, put them into an oven of 
moderate heat for twenty-four hours, when 
they will be completely dry, and fit for 
ule. Apply them with a gentle friction 
to the beard, and they will produce the 
complete effeét. of fhaving. 
Objervation.—As foon as we faw this 
patent compofition announced, our expec- 
tations were raifed, and we heped that a 
portion of our daily labour would no lon- 
ger be neceflary. How much we were 
difappointed every reader will eafily con- 
ceive, when he underitands that, inftead 
of the operation of foap and a razor, the © 
ufé of a new-formed grinditone is recom- 
mended. What effect iron pumice-{tone 
_ will have on the lips and chin, we know 
not from experience; but we fhould not 
expect that the operation would be either 
very ealy or very quickly difpatched.

MR. GEORGE MEDHURST’S (BATTLE- 
BRIDGE) for a condenjing WIND-EN- 
GiNE, capable of being apptied ta all 
KINDS of PURPOSES im which STEAM, 
WIND, WATER, or HORSES are ujed. 
We fhall find more difficulty in deferib- 
ing the merits of this invention, than we 
did thofe of the laft. The drawings that 
accompany Mr. Medhurft’s fpecification, 
are neceilary to the illuftration of his ma- 
chinery. He firft condenfes the air of the 
atmo(phere, in a ftrong and clofe veffel, by 
means of a wind-mill, fo as to make it 
from ten to twenty times more denfe tnan 
it is in its natural ftate : the dente air from 
the magazine is conducted through a pipe 
to the top of a cylinder, where it afts upon 
a pifton, by its elafticity, without the aid 
of fire, and by thefe means keeps the ma- 
chine in conftant motion for a tine, pro- 
portioned to the capacity of the magazine, 
though the wind do not blow. The object 
of this invention is to accumulate and pre- 
ferve the irregular power which the wind 
produces, fo that it may be ap »lied to 
machinery, to produce an unitorm and 
regular motion whenever it is wanted. 
The wind-mill fails are conftruéted in the 
ufual vertical manner; but if a greater 
power is required than can be obtained in 
that manner, they are then conflructed ac- 
‘cording to a method defcribed in the {pe- 
cification. 
By means of an inclined plane and 
{crew, the condenfing piften is made to 
work a long or a fhort ftroke according 
to the ftrength of the wind, and the.den- 
fity of the air in the magazine. When 
the wind is ftrong, or the air in the maga- 
zine not much condenfed, the inclined 
plane is to be fet at a great angle, that 
the pifton may make a long ftruke, and 
drive into the magazine a greater quantity 
of air; but when the wind is weak, or the 
air in the magazine ftrongly condenfed, 
the inclined plane muft be fet at a lefs 
angle. Thus the full effect of the leait 
wind will be obtained, as well. as of the - 
greatelt. 
The regulator for raifing or depreffing 
the inclined plane is next defcribed by 
means of drawings: and the form of the 
magazine is faid to be {pherical, or cylin- 
ical, with femi-{pherical ends, 2ecor/ing 
to the fituation and circumitances. The 
materials are copper, plate-tron,r cait- 
iron; and when large, caft or wrought 
into fegments, ana {crewed together, 
being painted or varnifhed in the infde, 
to make them air-tight. Where it is 
practicabie, fays the patentee, ‘‘ I make 
an excavation under ground, fo much be- 
low the furface, that the incumbent carth 
may be fufficient to refit the force of the 
confined air, and line the excavation with 
lead, copper, or caft-iron, or with bricks 
or tiles cemented together, and covered 
on the infide with pitch, paint, varnifh, 
or any bituminous matter, to render it 
air-tight; and to and from the magazine 
I condué& the air by a firong calt iron 
pipe, on or near the top of which mult be 
a fafety valve, for the fecurity of the ma- 
gazine, and a ftopt cock, to clole the pipe 
occafionally.”
