The Unitarian Society, which has, dif-

cheap form, of very many, valuable theo- 
logical works, is now about to printa very;

{t has been lately recommended that, 
excepting the lancet. employed — in 
vaccination, all the mftruments of fur- 
gery ought to be dipped into oil at the 
moment when they are going to be ufed; 
by which method the pai of the fubjéct

Mr. Hermestanr, of Berlin, gives 
the following as a cheap Method of ob- 
taining the Sugar. of the Beet-root :— 
Let the beet-roots be pounded ina mor- ° 
tar, and then fubjected to, the prefs; 
the juice is next to be clarified swith lime, 
like that.of the fugar-cane, aud then by 
evaporation bring it to the confliftence

thus. obtained, 80 lbs. may be had by 
the firit refining, of well+erydiahzed fugar, 
inferior neither in quality nor whiteuefs 
to that of the Wett-Indies: Two. days 
are {ulicient to complete the operation.

A new branch ef icience, entitled, 
Bnemonica, is now much fiudied in Ger- 
many, It was originally taught and, 
practifed in Egypt and Greece, and was 
ah inveution attributed to Simonides. 
The moderp refiorer of this art is M. 
ARETIN, who exacts from his pupils a 
proynife not to write down his: lectures. 
According to a book, faid to have been 
written by a child of twelve years of age, 
and mentioned in the catalogue for the 
laft September fair at Leipiic, mnemonica 
is a trae {cience, and may be fo taught 
as to give a memory to individuals of 
every age.*

M. Lescnryin, Chief Commiffary for 
Gunpowder and Saltpetre at Dijon, has 
fugyetted a method of averting thowers 
of hail, and ditlipating ftorms. The Me-

very, as he conceives, is long, but we 
fhall be able to prefent the Englith reader

capable of thaking the particles of water 
adhering to it, fo as to produce abundant 
rain: this is to be done: by the found of 
great bells, the noife of guus or drums, 
by the detonation of the filminating 
powder, and by the explofion, in the 
middle of the clouds, of rockets diretted 
towards the place where the clouds are 
thickett. (2.) He would eftablith ener- 
getic conductors between the clouds and

dittance to diftance, and kept burning by 
fupphes of dry fubltances, or by the dil- 
engagement of humid vapours, or the 
combuition of refinous matters. (3.) He

_ Dr. Carravort, in oppofition to the 
experiments and conclutions of Meffis. 
Hombolt and Gay Lufac, affirms that 
ebullition is not fuficient to free water 
from-all the oxygen that it contains; and 
that nothing but congelation, and thé 
refpiration of fifhes, can entirely clear 
Water of its oxygen. Thefe, he fays, are 
the only means tliat complete the {epae 
ration from water of all the oxygen it 
contains interpofed between its globules, 
Vithes he conceives to be the eudiometers 
of water; and one of thefe, fhut up ia 2 
body of water, is capable of feparating, 
by means of its retpiration, in feverat 
hours, all the oxygen from the water, 
and to exhauft it entirely from this prin- 
ciple. By feveral ingenious, but cruel, 
experiments on fith, this philofopher 
proves that melted fnow, as well as 
water that has been congealed, is de- 
prived of all its oxygen: , a 
M. Leror, who has made many fuc- 
cefsful experiments in agriculturé, ad- 
vifes perfons by no means to procure 
grain for fowing from a foil north of their 
own land, but from a country fouth of 
it; becaufe he fays it is a general rule, 
that the product of feed improves in gu- 
ing frou fauth to nerth, and that it des 
creafes in virtue in going from north to. 
fouth. He recommends boiled carrots 
as an excellent and cheap food for the 
fattening of pigs; and he adds, that by 
ficeping raw Carrots in water to deprive 
them of their acrid principle, then by
