to be completed in about ten volumes, 
under the title of Pantologia,- wall make 
its appearance in a few weeks. It will 
comprehend Essays, ‘Treatises, and Sys-

wise a general Dictionary of Arts, Sci- 
ences, and Words. It is intended to 
publish it in.parts, three of which will 
make a volume in royaloctavo. The au-

Lord Hottanp has announced his in- 
tention of publishing, in the course of the 
present season, the unfinished Fragment 
of the Historical work of the late Mr. 
Fox, relating to the House of Stuart. 
Mr. Fox, it is well known, had made lit- 
~tle progress in this werk, and he had 
long Stated to his friends the improba- 
bility of his ever being able to finish it. 
The loss of the Stuart papers conside- 
rably impeded his progress, and his ac- 
cession to office previously to his death, 
rendered his original design altogether 
abortive. 
Lorp Vaxentta has sent to press his 
Voyages and Travels to India, Ceylon, the 
Bed Sea, and Evypt, in the Years 18 302, 3,4, 
and 6. They will make three volumes, 
a will be printed in royal and imperial 
quarto, and be embellished with foxty- 
five highly finished engravings, tovether 
with other plates, such as inscriptions, 
maps, &c.

A globe of fire was perceived in open 
day in the month of September last, 
to pass over the island of Fulnen, 
which appeared to be constantly in mo- 
tion, and out of which flames and sparks 
were seen coming, in spite of a bright 
sun-shine. The direction of this meteor 
was frotu north-east to south-east. A si- 
milar phenomenon was observed in Jut- 
land, at the saine time, and in the same 
direction.

The large caldrons employed in bleach- 
fields, to contain the ley, are forined of 
several sheets of lead joined together, by 
the usual solder, composed of lead and 
tin, this solder is swfiiciently durable, as 
long as the caldrons are constantly em- 
ployed, but if the labour be interrupted, 
and the caldron remain empty for some 
months, it becomes oxidated to sucha 
degree, that it is found necessary to re- 
solder the plates of lead, before the ves- 
sels are fit for use. A portion of this 
solder was transmitted by the Count de 
Sorgo, to M. Vauquelin, who, on exami- 
nation, found it to be almost entirely 
composed of carbonized oxide of lead, 
containing afew particles of iron and tin, 
From this examination, and the infor- 
mation which he received, concerning 
the circumstances attendant on this phe- 
nomenon; he was of opinion, that the 
metals composing the solder were oxided, 
by the influence of the air_on the alkali, 
and that, in time, the carbonate of potash 
had been decomposed; or, in other words, 
that the alkali lad become united to the 
tin, while the carbonic acid had com- 
bined with the oxide of lead. Witt 
the view of verifying this conjecture 
by direct experiment, he took nearly 
equal parts of oxide of tin and ox- 
ide of lead,.and heating them slightly 
with a solution of carbonate of potash, 
the tin was dissolved, and the lead carbo- 
nized. Hence it is evident that a mix- 
ture of oxide of tin, and oxide of lead, 
possesses the property of decomposing 
the- carbonate of potash, and that this 
experiment affords a very plausible expla- 
nation of the change, which the solder 
undergoes from the action of the air and 
the alkaline ley. 
There has, we understand, for some time 
past been sold in Paris, as an object of 
amusement, a ‘detonating powder in- 
closed in slips of cards cat lengthways. 
The powder is placed at one end of this 
slip, and the other end is made smaller 
in order to render it more easily distin- 
guishable. When the other end is held 
over the flame of a candle, it speedily de- 
tonates with considerable moise, and a 
violet coloured flame; the card is. reptin
