large dictionary received from China, and 
by fome others already exifting in London. 
Mr. COLQUHOUN is preparing for the 
prefs, a Treatife on the Commerce and 
Police of the River Thames : containing 
an hiftorical view of the trade of the Port 
of London ; the depredations committed 
on all property imported and exported

the means of future prevention, by a com- 
plete fyftem of river-police ; with an ac- 
count gf the functions of the various ma- 
giltrates and others exercifing or claiming

woducing a degree of artificial cold much 
2ore intenfe than was ever before known.

ous evaporation takes place at the moment 
of union, accompanied by fo rapid an ab- 
forption of heat, as not only te congeal 
mercury, but even to reduce the gazeous, 
nitrous acid to a liquid form. 
In the Tranfa&tions of the Sucieté Phi- 
lomathique, is a Memoir by Montgolfier 
and) Argand, on a new Hydraulic Ma- 
chine ; which in principle, and even in the 
plates which accompany it, is fo perfeét 
a relemblance of Mr. Boulton’s patent 
“ for raifing water’? (See M. Mag. for 
Augult, 1798), that they muft both necef- 
farily hate had one common origin. It is 
of fome importance to Mr. Boulten’s cre- 
dit as a natural philofopher,; and to his 
right as a patentee, that this fingular cir= 
cumftance fhould be explained. 
The fulphat of f{trontites, a mineral 
lately difcovered near Briftol, has fince 
been found near Toul, in the department 
of La Meurthe; at Mefnil Montant, near 
Paris ; and in the Ifland of Sicily: from 
its general refemblance to the ponderous 
{par ({ulphat of barytes) this latter may 
have been frequently mittaken for it, 
An ingenious method of fupplying the 
piace of Horn for Lanthorns, &c. has 
been lately practifed in France. It con~ 
fits in dipping a piece of network of very 
fine brafs-wire in a ftrong decoétion of 
ifinglafs, which fills t1p the mefhes, and 
is converted by drying into a hard tranf- 
parent plate. It may be made of any 
thicknefs by dipping the netting a fuffiei- 
ent number of times, and when varnMhed, 
for protection againitthe eftects of moifture, 
is found to be as durable as horn, 
A ‘German tranflation of Dr. Woop-

is announced in the Jena Literary Journal;

But few experiments have yet been made 
with the view of afcertaining inwhat way 
common manures promote the growth of 
vegetables ; from what has been done, it 
would however feem, that fuch fubftances 
merely fupply the carbonaceous principle 
which is effential to all plants. The re- 
fult of praétical atrempts likewife fup- 
ports this fuppofition, as it is found, that 
the effeéts ot thefe matters are for the moft 
part in proportion to the quantity of this 
principle contained in them. 
The utility of turnips is fo great, that 
every fact refpecting them demands the 
attention of the farmer. Thefe crops 
fhould not be fown too foon, as they are 
very apt to mildew, and by that means be
