Six Canzonettas, with an Accompaniment for 
the.Piano-forte. “Dedicated to the Countess of 
Besborough, by W. H. Pollard. 8s. 
The style and general merit of these 
eanzonettas entitle then to our favoura- 
ble report.. An easy, unconstrained 
fancy characterises the various melodies, 
while the sentiment of the poetry is suc- 
eessfully consulted, and the basses and 
accompaniment prove the taste and sci- 
ence of the composer, who,we understand, 
isa young candidate for public favour. 
Al French Air, arranged with Variations jor 
the Piano-forte. Composed and dedicated to 
his Pupil Miss Fane Cassels, of Winyaw, by 
SF. Fay. 2. Gd 
The variations Mr. Jay has given to 
this air are engaging and ingenious, and 
cannot but do him credit with piano-forte 
students, who will find init muchimprov- 
ing practice. With the third variation 
we are particularly pleased: yet Mr. J. 
will excuse our noticing a fault in the 
motion of the upper part in passing from 
the sixteenthto theseventeenthbar. Mr. 
Jay,we are certain, does not require to be 
told, that when the melody forms a se-

Number VIL. of the Cabinet, consisting of Ron- 
dos, Airs with Variations, and Military 
Pieces for the Piano-forte. Composed and ar~ 
ranged by F. Woelfl, Esq. 45. 6d. 
The present number of this useful and 
pleasing little work consists of “ Fair El- 
len was a gentle maid,” composed by Mr. 
Hook, which Mr. Woelfl has arranged as 
arondo. As an agreeable piece for the 
piano-forte, and a proper and improving 
exercise for young practitioners on that 
instrument, we feel ourselves warranted 
in recommending it to the noticé of mas- 
ters and pupils, 
Grazd Sonata for the Piano-forte. Dedicated 
to Lady Blayney, by Signor Domenico Brisco~ 
li, Composer and Director of Music to the 
Louth Regiment, Master of the Reyal Callege 
of Pieta di Torckini of Naples. 3s. 
The subject of this sonata is bold and 
spirited, and the passages follow each 
other with an animated and happily-va- 
ried effect. The rondo with which the 
piece concludes is light and airy in its 
style, and calculated to please the genes 
rality of hearers,

MR. JEWEL'S, (STRATFORD LE BOW,) for a 
‘Method of preparing or reducing Calo- 
mel to an impalpable Powder, by which 
the Process employed in levigating it is 
rendered unnecessary. 
{ALOMEL as usually prepared, is a 
» hard crystalline substance, that re- 
quires various and rather tedious opera- 
tions to bring it to a state adapted to 
yodical purposes. The object of the in- 
vention before us is to produce the effect 
of the grinding and trituration in a more 
perfect and at the same time in a more 
simple way. The calomel is to be broken 
in pieces, and put into an earthen cruci- 
ble of a peculiar form. “I place,” says 
Mr. Jewel, “ the crucible on its side in 
a furnace with an opening through which 
the mouth of the crucible projects about 
aninch. I then join to the mouth of the 
erucible an earthen-ware receiver, having 
an opening at its side to receive the open 
end of the crucible: this receiver is about 
half filled with water, The joint is luted, 
and the receiver has a cover, which cover 
has a side continued upwards for contain- 
ing water, with a chimney or tube in it to 
allow the escape of steam from water be- 
low. I then apply a fire round the cru- 
cible sufficient to raise the calomel in va- 
pour, and foree it through the mouth of 
the crucible into the receiver, where, by 
the water while cold, or assisted by the 
steain when it becomes hot, it is instantly 
condensed into an impalpable powder,” 
This patent does not rest upon the sliape 
or composition of the apparatus ; but 
Mr. J. claims, as his own jnvention, the 
method of rendering calomel fit for me- 
dical purposes, by sublimation or distil- 
lation so conducted as suddenly to con- 
dense the vapours, and prevent the con= 
cretion or crystallization of the product.
