To WILLIAM Kendrick, of Binning- 
ham., for a Combination of Apparatus 
for Extracting tanning matter from 
Bark. 
The patentee exposes the fresh or 
"waste oak bark, or other material from 
which he is to obtain the tanking mat¬ 
ter, to the action of steam, or of water 
heated considerably above the boiling 
point. His apparatus consists of a 
boiler capable of generating them at an 
elasticity, that its pressure shall be not 
less than from eight to twelve pounds 
upon the square inch ; and from this 
boiler or steam vessel the steam is con¬ 
veyed into a vessel'containing the bark 
or substance from which the tanning 
matter is to be extracted. Tlie steam 
from the sleam-condueting-pipe is 
equally diffused in the vessel of bark, 
by a pipe which reaches nearly to the 
bottom of the vessel, and pierced with 
small holes in every part of its length. 
Observations. In this patent, (which 
we have no doubt is effeetrial as to its 
general object) there are gross and 
striking incongruities, which it is the 
responsible duty of a reporter to notice 
in the way of caution to others. The 
title of the patent is for an apparatus , 
for extracting, &c, the specification ex¬ 
plains no apparatus, but gives a general 
account of a method or process , and m 
the description, of which there is net 
precision enough to enable an inex¬ 
perienced person to effect it without a 
course of experiments of his own.

I T is a fact interesting to science and 
important to (he progress of aeros¬ 
tation, that the Balloon which ascended 
from the Green Park, on the day of 
the Coronation, was filled with or¬ 
dinary coal-gas, or carburet ted hydro¬ 
gen, instead of gas prepared from 
sulphuric acid and zinc, or iron filings, 
by the usual tedious and expensive pro¬ 
cess. A pipe was laid on to the main 
which supplies the street lamps, and 
the balloon was filled wifliout solici¬ 
tude in a shorter time than the same 
operation was ever performed before, 
and at the expence of £5. Taking the 
gas at .555 and the diameter at 32 feet, 
the power of ascension exceeded 7 cwt. 
Of course the machine acted well, and 
the ascent was one of the most beauti¬ 
ful ever beheld since the first ascent 
of Lunardi, in 1785. The varied cur¬ 
rents of air in the atmosphere were 
strikingly exemplified. The wind was 
nearly east; but, at.a certain height, 
the balloon was wafted northward, then 
eastward; and it fell at the distance of 
only thirteen miles, after making tra¬ 
verses of nearly fifty miles in forty-five 
minutes. 
Another novel, under the title of 
The Pirate, is preparing by the pro¬

sion of Augustus to the Death of Anto¬ 
ninus the Younger, will soon appear, 
from the pen of Mr. W. Haygarth.

prove a desirable work.
