oe perfection of mufical founds, 
depends muck upon the delicacy of 
the inftruments whéech are employed to 
produce them. No excellence of thofe 
which we frame can equal the powers of 
the human voice: even to give tothe hu- 
man voice its moft exquifite mutical ex- 
preflion, there are required a foundne‘s 
and a delicacy of the organs, fuch as.are 
not often to be found long co-exiftent. 
There is hothing that requires higher me- 
chanical ingenuity, than the conitru&tion 
of thofe mufical inftruments which are the 
work of art. 
Prodigious is the improvement which 
mutt have taken place in all that relates 
to mufic from the time of the /bell, the 
cymbal, and the ruftic pipe Se taes to 
that diverfity and complexit y of ftructure 
which are dilpl. ayed in the inftruments of 
our modern muilicians. It is but vain 
talk that afcribes to the mufic of the 
ancient Greeks, a power over the emo- 
tions and ae Hou of the human heart, 
fuperior to that of the more complex, Had 
richer harmony of our cotemporanies. 
Tt is not long fince many of the finett of 
the inftruments of muiic were to be 
found in greater perfection in Germany 
and Italy than in Great Britain; but, 
the wealth and grandeur of the great 
imperial and commercial capital of 
London, have, at laf, we believe, fixed 
in it as well the moft ingenious makers 
of mufical inftruments, as the ableft 
muficians in the world. Mufical inftru- 
-ments are exported from London to many 
parts of the European continent, as well 
as to all the more diftant dependencies of 
the Britifh empire in the Eait and the 
Welt Indies. 
It istheretore, with very great pleafure, 
that we fee new. improvement made 
wpon fo agreeable an inftrument as the 
Tambourine. Mr. Joserx Dae, an 
Wgenious mufical-initrument maker in 
the parifh of Mary-le-bone, has lately 
ebtained a patent for an improvement in 
the head of this inftrament, which is 
likely to prove of very eflential utility. 
We refpect the rights of the patentee too 
highly to enter into a minute detail of 
the peculiarities of his invention; let it 
be fufficient to mention, that, by means 
of it, a more convenient tention, and the 
upper part of the infrument is made more 
apt to the fingers of the mufician. We 
_ feould hope, that inftruments with this 
improvement, will be fo generally pre- 
ferred, as to afford an ample reward to 
the ingenuity of the inventor; for, in a 
matter of fo much delicacy as mufic, 
even changes apparently the moft flight, 
may prove. marcel of very high im- 
portance. 
MR.HICKLEY’S PATENT FOR BEAU- 
TIF ¥ING AND IMPROVING CHEMICAL 
AND CULINARY VESSELS. 
Scarcely any of the arts of fecond- 
dary neceflity are more ufeful than thofe 
of the potter and the worker in metals, 
which furnifh us with the common veflels 
for the kitchen and the table, and with 
other utenfils of familiar demeftic ac- 
commodation. We may itill contemplate 
with enyy the exquifite models of the 
ancient efrufcaz vafes, and the inimitalsle 
{emi vitrification of tome of the porcelain 
of Chzza: ut it cannot be denied, that 
the potteries and the caft-iron works of 
Britain, now provide many more elegant 
utenfils for the fervice of ordinary lite, 
than are known to have been furnifhed by 
the arts of any other country or any 
other age. 
The mere hardening of moulds of clay 
in the fire, could have, comparatively, 
but little utility, were it not for that 
fuperfictal vitrification of thefe moulds, 
which fits them, fo fuitably, for culinary 
ules. Chemittry teaching the choice of 
the proper earths, has contributed to per- 
fect the manufaéture. We form from the 
moft common and bale materials, a f{pe- 
cies of veflels more elegant and falutary 
in the ufe of them, than any that could 
otherwife be produced from matters the 
moft precious and rare. The colours, 
too, which the Englith potter knows how 
tocommunicate to the veflels which he 
frames, and the 6affo-relievo figures which 
he can imprefs upon them, make a won- 
derful improvement of their beauty. 
Mr. SAMUEL SANDY HriCKLEY of 
Birmingham, has obtained a patent for an 
invention in pottery, which will give new 
durability and elegance to the productions 
of this art. A mixture of filex or gra- 
nite in powder, with certain proportions 
of litharge, and nitre applied to any 
earthen vetlel, and expofed to a vitrifying 
heat, has been found by Mr. HickKLiy 
to give a degree of ftreagth and exterior 
beauty, fuperior to whatever can be, by 
other means, produced in this manufac- 
ture, His patent enables him to ute this 
invention in pottery, without danger of 
being immediately deprived of the benefit 
of it, His invention, however, extends 
ftild
