A pound of sugar-candy dissolved by 
heat, in a quaftity of white-wine 
vinegar, and evaporated to the measure 
of one pint, during which operation as 
much garlic as possible is dissolved with 
it, answers all the purposes of Godbold’s 
vegetable balsam, and is probably. the 
same medicine. | 
The following details, relative to the 
coal-gas flight, one of the greatest improve-~ 
anents of which modern times can boast, 
are taken from an mteresting Memoir 
read before the Philosophical Society 
of Glasgow, by Mr. Ricnarp Git- 
LEsPreE, by whose public spirit, and 
at whose works, this greatexperiment of 
permanently lighting an extensive manu- 
factory by yas, was first undertaken in 
Scotland. ‘The apparatus, made by 
Bolton and Watt, was -fitted ‘up at 
Anderston the-latter end of last summer, 
vod Mr. Gillespie's works were illuminated 
in thisinanner at the beginning of Novem- 
ber. Since that timesome great improve- 
ments have been made; and the whole 
now constitutes a very-pleasing exhibition. 
—Two iron retorts, of a semi-cylindrical 
form, each capable of containing about 
one cwt. of coal, yield at every charge 
780 cubic feét of gas, which, after being 
' wa-hed, soas to deprive it of any disagree- 
atie smell, is conducted into a large cu- 
bical plate-iron gasometer, of a capacity 
equal to 1120 cubic feet. The gas evol- 
ved by the regular process of carboniza- 
tion, during the day, is here stored up 
for use. From this magazine, which floats 
in a water cistern, a main pipe issues, 
which afterwards branches into innumera- 
ble ramifications, some of them éxtending 
sereral hundred feet under ground; thence 
to emerge, diffusing over a multitude of 
apartments a kind of artificial day; so 
vivid is the illumination. The flame, 
however, though exceedingly bright, is 
very soft and steady, and free from that 
dazzling glare which has been so greatly 
complained of in the otherwise beautiful 
light of the Argand lamps. No trouble 
attends this mode of illumination; the 
occasional attendance of one man in the 
gas-house, to charge the retorts, and 
mend the fire, being all that is ne- 
eessary. On turning a stop-eock, any 
particular flame may be kindled im- 
mediately, and no trimming or snuffing is 
required ;—neither are any sparks thrown 
off, as from a burning wick: 14 cubie 
feet of gas yield the same quantity of light 
as a moulded candle of six in the pound, 
which is found, on the average, to last 24 
hours. The contents of the gasometer are 
Literary and Philosophical Intelligence. 
867 
therefore equal to 900 such candles. To 
‘fill it requires three cwt. of coals, va- 
lue at 6d, each cwt., 1s. 6d.; coal for heat- 
ing the retorts during the composition, 
is.—Hence, for 2s. 6d. a quantity of light 
1s procurable from coal gas, which obtain- 
ed from candles would cost about 10/. 
But from the above charge for coal, we 
must deduct the whole expence of what 
g0es into the retart, for this acquires addi- 
tional value by being charred, and is eazer- 
ly bought up by the iron-founders. A 
large quantity of tar is also obtained 
in the condensing pit, as well as ammo- 
niacal liquor, from hoth of which con- 
siderable returns may be reasonably ex- 
pecied. : 
_A new species of fiorin grass has heen 
discovered at Llarfain, in North Wales, 
by Dr. Princ, which promises the mast 
important advantages to the agriculturist. 
It is of the most luxuriant growth, and 
calculated to produce green food during 
the four winter months. One of the 
roots, transplanted by Dr. Pring, contain- 
ed 27 stalks, six feet in height, and bear- 
“Ing 277 ramifications.

A new method of ornamenting all kinds 
of glass in imitation of engraving, &c 
has recently been discovered. By this 
invention, the tedious and expensive pro- 
cess of grinding by means of a machine 
with wheels is exploded, and in lieg of it 
an additional surface or coating of glass, 
‘prepared for the purpose, is substituted : 
which, when subjected to a proper degree 
of heat, will incorporate with the glass to 
be operated upon, so as to produce an 
effect similar to that which has hithertg 
been obtained by means of grinding. The
