A new edition of Dr. Curriz’s Re- 
ports on the Effects of Water, cold and 
warm, in the Cure of Fevers, will fhortly 
make its appearance. It will contain much 
additional teftimony in favour of the prac- 
tice of cold affufions in the various {pecies, 
of fever. 
The Rev. Mr. TuRNER, of Newcaftlé 
has in the prefs a difcourfe ‘* On the Love 
of Pleafure.”” 
The machineinvented by Mr. SMarT,* 
of Camden Town, for {weeping chim- 
nies, 
tubes, of about 30 inches long, and 
three qnarters of an inch in diameter, 
which run on a rope or cord, and faften 
into one another, to any length. To 
the upper tube is fattened a {quare bruh, 
the block of which is about fix inches long 
by three wide, and from it, on all fides, 
iffues heath, broom, or any other ftiff but 
flexible fubftance, large encugh to fill the 
breadth of the chimney. The tubes aré 
about 30 inches long, of courfe the joints 
between each will bend to the moft 
crooked chimney, and in coming down 
mutt clear out the corners, ledges, &c. 
which are fometimes found in chimnies. 
In the courfe of the prefent month Mr. 
Smart has, in the prefence of many re- 
fpectable witnefies, effectually cleanfed 
feveral lofty and crooked chimnies. So 
completely does this invention an{wer the 
plen propofed by the feveral focieties who 
ave undertaken to advocate the caufe of 
the poor climbing-boys, that nothing is 
now wanting to put an end to the com- 
mon mode of chimney-fweeping. By Mr. 
Smart’s method, a chimney 50 feet high 
may be {wept in fix or eight minutes, 
and with much Jefs dirt than happens by 
the common mode. 
Mr. Pepys, jun, has lately conftru&ted 
the moft powerful Galvanic apparatus 
that has been yet produced. It coniifts 
of 60 pair of zinc and copper-plates, dif- 
pofed in two troughs; conftruéted on Mr. 
Cruikfhank’s plan, but with fome ac- 
companying arrangements which are ex- 
tremely convenient and ufeful. The ex- 
periments made with this apparacus by 
* Mr. Pepys, on-the deflagration of metals, 
were the moft brilliant and fplendid ever 
beheld in Londen; of which the follow- 
ing account will give fome idea:—The 
troughs were filled with 32 pounds of 
water, mixed with two pounds of con- 
centrated nitrous acid. With this charge

Literary and Philofophical Intelligences 
confifts of a number of wooden. 
_ 259 
iron-wires of 54, to +4, of an inch in dia- 
meter were deflagrated with great f{plen- 
dour. A number of the {mall ones twifted 
together produced fomewhat like a little 
brufh deflagration.—-Charcoal of boxe 
wood was not only deflagrated at the 
place of conta&t, but remained perma- 
nently red-hot for near two inches in 
length.—Lead-foil burnt with great vi- 
-vidnefs, becoming red-hot, and emitting 
a {mall voleano or adjutage of red {parks 
with the flame.—Tin-foil burnt with 
great {plendour, with fmoke and fparks. 
—Dutch leaf or brafs-foil deflagrated 
vividly, with fmoke and a’ profufion of 
fparks.—Silver-leaf burnt ‘with an intenfe 
vivid green light.—Gold-leaf deflagrated 
with a white bright light —Tin-wire 4 of 
an inch in diameter, fufed, burnt, and 
oxidated, with great {fplendour.—Platina- 
wire = of an inch in diameter, became 
red-hot, white, and fufed into globules 
at the contact. Gunpowder, phofphorus, 
and inflammable fubftances, are inftantly 
fired by contact with conduétors armed 
with charcoal.—The Galvanic power was 
capable of deflagrating charcoal, after 
pafling through fixteen perfons with wetted ’ 
hands joined. 
The fecond edition, confiderably en- 
larged, of Dr. Asnwortu’s “ Eafy In- 
troduétion to Plane Trigonometry”’ will 
be publithed early in April. ” 
A paper has lately been read before the 
Royal Society, by Mr. HoME, on the na- 
ture of the tongue. His experiments on 
different difeafed tongues prove that this 
member is endowed with lefs irritability 
than any other organ of the body; and 
that a difeafed part may be removed with 
great fafety by means oi ligatures. 
The thermometer has been ufed in na- 
vigation to afcertain the diftance of a thip 
from the coaft: During a voyage from 
Engiand to New York, made by Mr. 
STRICKLAND, in the month of Auguf, 
there was obferved a difference of so 
degrees of the thermometer between the 
water on the bank, and that in the fame 
latitude in the ccean, not far to the 
eaft of it. The water of the ocean being 
the warmer. é 
From a number of experiments and ob- 
fervations made by M. CurisToPHer 
GULLET, on the effects of elder in pre- 
ferving plants from infeé&ts and flies, it 
appears to be ufeful—z. For preventing 
cabbage and cauliflower-plants from being’ 
devoured and damaged by caterpillars.— 
2. For preventing blights, and their 
effects on fruit-trees.—3. For preferving 
Noe corn
