NEW PATENTS LATELY ENROLLED. 
MR. HENRY SMITH’S (Lieutenant of the 
Nawy) for anew kind of VESSEL jor 
conveying POWDER from place te place. . 
HIS gentleman, from his fituation 
and experience, has witnefled many 
accidents which have happened in the con- 
_veying powder from the hoy to the fhip. 
Thefe are generally occafioned by the 
barrels, &c. being chiefly made of weod 
with copper hoops, the hammering on 
and taking off of which frequently produce 
{parks, and thefe communicating with 
the powder, prove inflantly fatal. To re- 
_medy this defeét, he propofes to make the 
veflels entirely of copper, and of fuch a 
fize as to be perfectly manageable, and to: 
be moved by the hand. “To the open- 
ing which admits the powder is to be 
ee in a plug with a fcrew, fo as to be 
completely water-tight. Over the plug is 
to be a handle, by means of which the 
cafk is conveyed from one perfon to arb- 
_ther without being once put out of the 
hand till it is placed in a fituation where 
it is toremain. Among the various ad- 
vantages enumerated are the following :—~ 
Jn the ufual method much of the powder 
3S damaged by the moifture getting 
through the barrel, which by the ufe of 
Mr. Smith’s veffel will be prevented. At 
prefent when powder is brought on board 
of fhip, the fides, decks, &c. are cbliged 
to be covered with hides and other fub- 
ftances, to prevent accidents from the 
friftion of nails, when the barrels are: 
relled along: but according to the new 
mode they are never permitted to be 
rolled, but are lifted from hand to hand. 
Befides thefe, there are other advantages 
zccruing by this method, with regard to | 
filling cartridges, by which time is faved, 
and much lefs powder wafted than ufually 
hzppens in fuch cafes.

MR. RoCHE’S (Bloom/bury) for a M=n1- 
CINE for the HOOPING-COUGH. 
The Patentee of this medicine, if fuch 
it may be called, profeffes not only to re- 
lieve, but wholly remove this painful and 
fometimes dangerous difeale by external 
application only. The médicine is com- 
pounded principally of effential oils in 
different proportions, as the oil of elder, 
the oil of- carraways, and the oil of rofe- 
mary, in which are mixed leaves of red- 
rofes, camomile flowers, &.; the whole 
is to be fimmered over a flow fire for the 
‘flate, or nearly fo. 
{pace of twenty-four hours, and then 
preffed through a ficve. The mode of ap~ 
plication is, to take a fmall quantity, ac- 
cording to the age of the patient, of this . 
Medicing: and rub it over the pit of the 
ftomach for about ten minutes before a 
fire, jult previoufly to’ bed-time; then 
cover the part with a flannel, which is to 
be kept on the whole night, and to be . 
exchanged for another piece of flannel in 
the day-time. The quantity ufed for an 
infant under fix months of age is only the 
third part of a tea-fpoonful, and to a 
child two years old a tea-{poonful is fuffi- 
cient for each embrocation.

MESSRS. GEQRGE and WALTER BEAU- 
MONT’S (Huddesfield) for a MIXTURE 
to be ufed in the preparation of SHEEP 
or LAMB'S WOOL jor Various pur- 
pofes 
This mixture _confifts of oil, united 
with, or difufed in, water, by means of 
an alkaline fubftance, fuch as potafh or 
volatile alkali; the former is, however, 
preferred by the Patentees, who give the 
following as the beft proportions :—Dif- 
folve twelve ounces of the beft potafh in 
each gallon of water ; them two parts of 
this folution are to be added to one of oil, 
and to be united by ftirring or agita- 
tion. ‘This compound liquor, thug 
produced, is that for which the patent 
has been obtained, and will, we are af- 
fured, be found to produce the effect of 
oil, when applied in the fame manner as 
oil is commonly ufed in’ manulacturing 
cloths, kerfeymeres, and every other de- 
{cription of woollen goods. ; 
Remarks.—In all the operations upon 
wool, the manufacturer endeavours either 
to extend it by carding or {pinning; or 
to condenfe it by weaving, fulling, telt- 
, &c. Inthe former cafe it is,necef. 
tary that the fibres of the woe! fhoald, by 
means of fome lubricating matter, be 
made to flide over cach other ; and no ma. 
terial has been before known which was 
adequate to the effect, except oil, ina pure 
Water of itfelf is 
too harfh, and {oon evaporates;, and the 
folution of foap in water, in the requilite 
proportions, becomes ftiff, and cloggs the 
fibres of the wool. But the patent liquid 
is difpofed to remain in the ftate of deli- 
quelcence. :
