is then fuffered to run off by a eock, into 
pits, where it flands to cool. The hides 
are put into the liquors, and bandied fre- 
quently, by taking them out, and putting 
them in again, becaufe the Jiquor is too 
powerful for them to remain jong at a 
time in the firt flages of the vrocefs. 
They are then to be removed to freth li- 
quors from time to time, as the old is 
weakened, until the cperation is com- 
plete. 
By this method they collect a greater 
quantity of the tanning principle into a 
fmal! compafs, confume !efs bark, and find 
a great faving of labour and wages. 
Another procefs is ufed with hides and 
{kins for drefling or currying after being 
baited: after they are well wafhed, they 
are put into a liquor that has been already 
ufed, from which they are put into other 
Iiquors, itronger and firenger, until they 
are tanned ; if leather is required with a 
whiter colour or bloom, a fmall quantity 
of the duft of bark is mixed with the li- 
quor. By this method, hides that have 
been fhaved in the baits, may be better 
tanned in two or three weeks, and fkins in 
ten or twelve days, than by the ufual pro- 
Review of New Mufical Publications.

cefs, in the one cafe, in nine months, and 
in the other, in fix months. 
For other operations, different modes *’ 
are prefccibed ; but the great ac vantage is 
that derived from ex:racting the tanning 
principle by means of boiling, as bufinefs 
to any extent may be carried on with 
about one-tenth part of the capital em- 
ployed on the old plan. Bedfides bark, the - 
patentees make ufe of oak chips, and oak 
faw duit: they have fucceeded with the 
common heath, or peather; aod they find 
that the bark of moft trees that produce . 
hard wood, has a tanniog principle in 
them ; but, above all, they recommend the 
young fhoots from the roots of oak treesy 
and the fuperfluous twigs or branches that 
may be iopt off fo as not to injure trees. 
Thefe, when cut in proper ieaton, may be 
chopped, and ground, and boiled with 
bark ; and will produce a ftronger tanning 
liquor than very old bark from the trunk 
of trees that have a thick ftrong cruft or 
rind upon them, and which cannot be 
got off from the bark. Thefe fubftitutes 
being made ule of, will tend to lower the 
price of bark, which is the moft expenfive - 
article in the manufaéture of leather.

REVIEW OF NEW. MUSICAL PUBLICATIONS. 
Twelve Voluntaries for the Organ or Piane-fortes 
compofed and dedicated to the Governors and 
Guaratans of the Foundling Hofpital, by Wil- 
liam Ruffel, Organift of the Foundlag of St. 
Anne's Limchouje. 10s. 6d. 
{ 7 E enter with much pleafure upon 
the tafk of noticing this publica- 
tion. Mr. Roffel, whofe profeflional me- 
rits are not fo well known to the public as 
they deferve to be, has by this produétion 
of thefe Voluntaries ranked himfelf a- 
mong the mott refpeciable Compofers in 
this fpecies of mufic. After a fedulcus 
peruial ef bis pages (49 in number) we 
find ii:tle that we are not greatly pleated 
with, 2rd much that claims our warmeft 
approbation and praife. The diapa/on, 
trumpet and fwell movements are ingeni- 
oufly and elabor:tely conftrudéted. Vhough, 
perhaps, in fome inftasces they are fome- 
times too long; and the fugues are not 
oniy difttnguifhed for the excelleacy of 
their /ubjedts, but are fe clofely and arti- 
ficially worked ag to exhibit in every bar 
the found and well ftudied mefician. 
With Mr. Ruilel’s pretentions as an organ 
performer we are hy no means unacquaint- 
ed; and we cannot but hope that the pre- 
fent publication will contribute to draw 
that attention to his talents and f{cience 
which they fo well merit. We were glad 
to fee a lit of fublcribers fo refpeétable 
in numbers ; and to find among the pro- 
feffional names thofe of Dr. Burney, Dr. 
Bufby, Dr. Callcot, Mr. Shield, Mre 
Baumgarten, and Mefirs. Wefleys.

The prefent colle&tion (the firft publi.

charaéterized by much fprightlinefs and 
variety; Every melody, we muft im can- 
dour fay, is at once adapted to the fenfe 
of the words, the powers of the finger to 
whom it is allotted, and the meridian of the 
place for which it is competed. This ob- 
dervation applies with particular propriety 
to ** Yow il never die for Love; and
