The mucb admired Cymbal Dance, in the New 
Pantomime of The Seven Champions. Com- 
-pofed and arranged for the Piano-forte, and 
as a Ductt for Flutes, by . Sanderfon. 
This dance confifts of an eafy flow of 
natural and connected paffages, and forms 
an exercife for the piano-forte which will 
be found ufeful to young practitioners. 
Its adaptation for two flutes is arranged 
with confiderable addrefs, and cannot fail 
to pleafe flute-performers in general. 
Hornpipe, as danced by Mifs Denny, in the 
Eclipfe, performed at the Royal Circus. Came 
pofed by W. Ware. 
Where little is meant, little ought to be 
expected. This hornpipe is but a trifle, 
but at the fame time, we muft fay, a very 
pleafing trifle; and it fets Mr. Ware's 
fancy, as far as reipeéts fuch limited 
efforts, in a favourable point of view. 
6¢ Poor Will,’ a Ballad, written by Mr. An- 
derfen. €ampofed by Thomas Thempjon, Or- 
ganifi, at Newca/tle-upon- Tyne. 
Neither the poetry nor the mufic of this 
[Dec. 1, 
fong poffefs any great claims to our ap- 
probation. The melody is flimly, and 
the lines dull and uninterefting. 
Air, with Variations for the Harp or Pians- 
forte. Compofed by Febn Langfbaw, Or- 
ganifl, Lancafier. 
We cannot beftow much commendation 
on this production. The theme is infi- 
pidly conceived, and the variations, 
though well calculated for practice, are 
dry and inelegant. 
Since our laft Number, a Mufical 
Afterpiece, called, A Tale of Myitery, 
tranflated from the French by Mr. Hol- 
croft, and forming a fpecies of drama en- 
tirely new to this country, has been pra- 
duced with fignal fuccels at Covent-garden 
Theatre. ‘The mufic is compofed by Dr. 
Bufby, and the high applaufe it has re- 
ceived from all degrees of the public will 
induce us to take the earlieft opportunity 
of prefenting our readers with our ftri¢- 
tures on ifs particular merits.

=a 
MR. GEORGE HUDSON’s (CHESTER) for 
ibe making or manufacturing of MiNE- 
RAL or FOSSIL ALKALI. 
HIS gentleman enumerates a great 
number of fubftances which he 
makes ufe of for the purpofe of obtaining 
the mineral alkali, with the particulars 
of each proceis in the manufacture. It 
will give. a general idea of his plan, to 
particvlarize the method which he takes 
with kelp; this is the fubftance that ftands 
moft prominent in the fpecification. To 
two hundred weight and a half of kelp, 
beat into very fmall pieces, or ground 
into powder, he adds one hundred anda 
half of foapers-afhes, and one hundred 
weight of wafte tan, which he mixes to- 
gether with water, or ether fluid, till it 
comes to a proper confiltency ; it then is 
to be taken and placed on the bettom of 
a reverbatory furnace, the conftruétion of 
which is fhewn by a drawing annexed to 
the fpecification; a ftrong heat is to be 
applied, and conftantly kept up, and the 
flame made to pafs over and att upon the 
mixture. At the interval of every ten 
‘Minutes, more water is to be thrown in, 
and more tanner’s wafte bark, and the 
whole to be kept moving about with en 
iron fpatula: at the end of four hours 
the fubftance begins to flux, and in about 
fix hours it will be found completely 
fluxed, and the operation finifhed.

MR. FORDER’S (PORTSEA) for @ ME- 
THOD of STOPPING the LEaks, &cs 
of SHIPS. 
According to the plan defcribed by the 
Patentee, all trifling damages fuftained by 
any veflels may be repaired without bring- 
ing them into dock. He has contrived a 
kind of diving-machine, made principally 
of copper and leather, the joints of which 
are to be rendered water-tight, by a fort 
of cement, likewife defcribed in the fpe- 
cification. Mr. Forder has not forgotten, 
that air and light will be wanted by the 
diver, for both of which he has provided; 
he feems alfo to have taken into confi- 
deration the immenfe preffure to. which 
the machine muft be fubject at any given 
depth below the furface, and has fo con-, 
ftruéted it, that it may fuftain the force : 
he has alfo a contrivance for taking down 
lighted candles, when the work is to be 
performed in the night. According to 
the plan which he has fabmitted to the 
public, the diver may remain-under water,
