Mr. Parnalls and Mr. Wilson's New Patents.

JOHN PARNALL's, of St. Austell, Corn-
wall, Brazier, for an Improvement of
Tinning Sheets of Copper, Brass or
Zink.-June 10, 1817.

By the present method, copper, brass or
zink cannot be tinned when in the form of
plates
:—the patentee accomplishes this ob-
ject by the following process. The sheet
must be bent for the purpose of placing it
upon the edge, and then put into a trough
containing a preparation of two pints of spi-
rits of salts or marine acid to three gallons of
water, more or less, according to the quan-
tity of the metal. It is next put into an air
furnace heated with coal or other fuel to
raise a scale; the sheets are then removed
from the furnace, and several of them put
together, and taken up with tongs and
struck upon an iron plate till the scale is
beaten off. The whole of this process must
be repeated till the original surface is taken
off and the sheet appears clean; it is then
passed through a pair of case-hardened iron
rolls turned very correctly to harden the me-
tal and give it a smooth and flat surface,
After this the sheet must be placed in troughs
of lees of fermented bran, which may be
produced by placing bran and water over
flues through which the fire or heat from a
stove passes, to bring it into a proper state of
fermentation; this process requires at least
the space of four days previous to the lees
being used. The sheet must remain in the
lees at least twenty-four hours, and then be
removed into a trough containing a mixture
of two pints of vitriolic acid and two gallons
of water; here it must lie four hours and be
washed till cleansed. It must then be put
into a trough of clean water and rubbed with
sand till perfectly clean, again placed in
troughs of clean water, and when taken out
dipped into a pot of melted tin with tallow,
grease, or any other more fit material on the
top, through which the sheet of copper, brass
or zink passes to the tin; but the greasy
matter may be omitted when the quality of
the copper, brass or zink renders it unneces-
sary. If required, the sheet is dipped into a
second tin or wash-pot filled with melted
tin, and then into a pot of grease to take off
any knob that may have formed, and leave
the covering of tin of a smooth surface. The
sheet is then rubbed clean with bran, and
passed through a pair of case-hardened,
highly-polished iron rolls, when it becomes
fit for use.

DANIEL WILSON's, Dublin, Gentleman, for Improvements in the Process of boiling and refining Sugar.—Jan. 23,

1817.

In the common process of boiling and refining sugar, the fire is applied directly at the bottom of the pan in which it is evaporated, and from the viscidity of the syrup and the strong fire which is essential to the operation, the heat is conveyed through the bot

[March 1,

tom of the pan more rapidly than it can be
communicated upwards by the carrying
power of the fluid, and a portion of the sugar
becomes burned or converted into molasses,
by which the quantity and quality of the
whole are decreased and injured. Mr. Wil-
son's improvement prevents the possibility
of this deterioration, by applying the heat by
means of a current of heated fluid which
passes under and round the sides of the pan
containing the sugar: and the fluids which
are thus used as the conveyers of heat are
of such a nature that their boiling points are
above the heat of boiling sugar, but below
the degree of heat necessary for burning or
decomposing it, so that it can never be in-
jured from an excess of heat. The pans in
which the sugar is boiled consist of two me-
tallic vessels one within another, with a
small space between each, and connected
by a flanch at the top. They are placed
without any fire under them, and the outer
pan communicates by means of pipes or
tubes, with a boiler or vessel, in which the
fluid for conveying the heat is heated. These
pipes of communication are at different le-
vels; for which reason, if the current be ex-
cited in the upper one by means of a pump
fan engine, or any other contrivance, so as
to make the liquid medium flow from the
boiler in which it is heated towards the ves-
sel in which the sugar is to be boiled: this
current will pass into the space between the
two vessels, give out a portion of heat to the
sugar in the interior one, and return to the
boiler by the lower pipe, in order to be again
supplied with the heat. Thus by means of
one boiler several vessels for the evaporation
of sugar may be boiled, and the rapidity of
evaporation increased or diminished by re-
gulating the current of medium to each,
which can readily be done by means of
valves. The substances which the patentee
employs for conveying the heat are any kind
of fish or vegetable oils, animal fat, butter

Apotheosis of Thomas Paine.

The friends of anarchy have, it seems, formed the notable plan for rallying their ragged regiment by hoisting the banner of THOMAS PAINE. On this subject the doughty knight, whose early attachment to the principles of this archincendiary procured him a temporary asylum in Leicester gaol, has the following triumphant paragraph in the last number of his Magazine:

Justice is about to be rendered by kindred genius to the memory and labours of the famous THOMAS PAINE, the energy of whose political writings led our base and corrupt factions to pay their dependants for burning him in every village of the empire. Mr. COBBETT, who reports that he lives within a few miles of the spot where this politician

breathed his last, has volunteered to become his biographer, and to rescue his memory from the blasphemies against the sacred majesty of truth, of which it has been the object. Mr. Cobbett proposes also to edite his works and adapt them to existing circumstances by original notes. We observe, at the same instant that Mr. Wooller, in his journal, proposes, evidently without participation, that the birth day of Paine should be publicly celebrated as an antidote to that of Pitt. It is a wonderful trait in the history of man that these popular testimonies in favour of Mr. Paine should take place no more than twenty years from his death, after he had passed a long life amid persecution, personal slander and ingratitude.

Our readers will not fail to admire the very happy expression of "kindred genius," as applied to THOMAS PAINE and WILLIAM COBBETT-Par nobile fratrum! The country too will doubtless duly appreciate the exertions of the latter worthy, to provide potent stimulants for disaffection, and to give new circulation to the dangerous doctrines of the apostle of anarchy, highly seasoned and "adapted to existing circumstances" by his own annotations. We recommend this information to the serious attention of all whom it may concern. The prescription of the political quack of the Black Dwarf excites only a smile, which extends to a broad laugh at the childish wonder of the writer at these popular testimonies -to wit, of two jacobin scribblers in favour of Mr. Paine. On the phrases"base and corrupt factions,"" blasphemies against the sacred majesty of truth," and the like, it would be a waste of time to comment, as the editor of the Old Monthly Magazine has worn them so threadbare by constant use, that the most short-sighted cannot but see through them. Such expressions might be expected of the man who talks of" the mo

on record, it would be sufficient to convince every person of the vast importance of a method which shall effectually preclude the possibility of the recurrence of such a disaster.

From some late microscopic experiments of Sir EVERARD HOME and Mr. BAUER, it results, that 2,560,000 globules of human blood, when enveloped in their colouring matter, which is conceived to superadd something to their proper substance, would be required to cover a square inch.

Lieut. SHILLIBEER, of the Royal Marines, has addressed a communication to the Navy Board, on the prevention of dry-rot in timber employed in shipbuilding. He asserts that this destructive disease would not appear, if the tree were cut down at the end of December or beginning of January, and left with its bark on, instead of being felled in April, and having its bark stripped off, according to the usual practice in this country. At the latter period its pores are open and extended to receive the great quantity of sap which is thrown up from the roots into the trunk and branches. The tree is then soft and easy to be cut; in this state it is left to season, the sap is dried by the sun, but the pores never close, neither does the tree become that solid mass which it was before, but soon becomes infected with dry-rot. If on the other hand, a tree be suffered to stand, until the vegetation has entirely ceased-sayChristmas-the sap will have returned into the roots; the pores will be naturally closed; the bark will be found inseparable; and the tree, when cut and seasoned, for a comparatively short time, will be so hard and impenetrable as not to be liable to the disease. The difference between trees treated in these two methods is striking; the one being soft, open, and coarse-grained; the other close and solid. The Board has attended with laudable promptitude to this suggestion, and directed that no timber which has been barked shall be received into Plymouth Dock-yard.

A valuable mine of plumbago or graphite was last summer discovered at Glenstrathfarar, about 30 miles from Inverness. It promises to be of considerable importance, as there are, we believe only two mines wrought in Great Britain for the production of this useful article.

A late number of the Norwich Mercury gives a brief account of the esta blishment, regulations and proceedings of the NORWICH PHILOSOPHICAL SOCIETY. It was instituted in the autumn of 1812, when a number of gentlemen agreed to meet every Thursday fortnight for the discussion of literary and philosophical subjects. Each member engages to furnish some communication to the society once at least during every two sessions. At the commencement of the session of 1814, it was resolved to chuse a president, vice-president, and secretary annually, and Dr. Rigby was elected to the chair. During the present session the following papers have been read:

"On miscellaneous diseases." "Human law founded on natural law."

"On architecture."

"An account of the manuscript papers left by the late Right Hon. Win. Windham, prefixed by a short history of that great man."

"Remarks on painting, as connected with poetry."

The last of these essays is by Mr.J. CROME, jun. a young artist who is rising rapidly in his profession and in the public respect.

The discussions have of late been very fully attended, and the debates are ge nerally spirited and interesting, while the effects in stimulating youth to literary pursuits are obvious. Norwich is become emulous of intellectual distinction. The attention of Dr. RIGBY to the Society, who has been continually re-elected to the chair, is so unremitted that, in spite of his multifarious and frequently very distant engagements, he has never been absent. This energy in the cause is reciprocated between the head and the members, and is felt throughout all the relations of general intercourse with which the individuals composing the Society are connected. Hence the intellectual cultivation of Norwich has already received a considerable impulse, and will continue to experience beneficial results from the useful and agreeable industry of the Society, to the proceedings of which it will give us great pleasure to be enabled, by the enlighted president or any other of its members, to pay that attention which they deserve.
