Tt bas hitherto been the custom to 
make these kinds of vessels in wood, but 
the patentee proposes to substitute irou, 
or other metals, in the place of wood ; 
and in cases wheré the vessels are too 
large to be formed of one piece of metal, 
we have precisé directions with draw- 
ings, shewing 1h what way two or more 
pieces aré to be united. 
When two plates, or pieces of cast or 
tialleable iron, are-to be united, they 
may be joined together. by a rabbitsjoint : 
fey may also be prepared for jommg to- 
gether by flange joints; by an overlap 
joints; hy an invested on, or Hiss sang 
or flat joint. 
When. the piates of iron are thus-pre- 
pared, Mr. D. makes use of some’ ie 
mal, vegetable, or mineral substan 
prepared in the form of paste; but in 
cases where the vessel is likely to be ex- 
posedto any desree-of heat, the paste, or 
gement, IF tO COnsist of pulerized iran,

mixed with a small portion of salts and 
sulphur, which causes it to unite ‘with 
iron, and will bear almost an equal de- 
gree Of heat with the tron itself. Allthe 
cavities, or spaces, between the parts of 
the plates to be united, are to be filled 
with the cement, and ‘the plates them- 
selyes are then to be screwed, riveted, 
er bolted toyether, and thus a vessel of 
almost any size may. be formed pertectly 
strong, and capable of,any Service. 
We have in the speciGcation before us, 
descriptions of various kinds of vessels, 
which are also represented by drawings. 
Speaking of the cooler, he says, this ves- 
sél is constructed so as to produce a 
large surface to the surrounding atmos- 
phere; but when filled with hot. ‘liquor of 
any sort, the surrounding air is rarefied 
according to the degree of heat it pos- 
sesses, - ‘He therefore fixes in the bottom 
of his cooler, a number of hollow tubes, 
or pipes, which wall adimit a free passage 
for the air; which being rarefied by the 
heat of the bottom, will endeavour. to 
ascend, aslong as the vessel remains hot- 
ter than the atmosphére: thus a current 
of air will be continually ascending 
through the tubes, and the bottom will 
be successively acted upon by a fresh sup- 
ply of cold air, which will consequently 
accelerate the cooling of the liquor. By 
this method, coolers may be made to, oc- 
cupy less room, and produce the same 
effect as wooden ‘vessels made in the com- 
moh way. 
par, Dickson farther observes, that in all ° 
cases,inwhich liis metallicvesselsare found 
to afect: the fluids contained in them, he 
fines them with tin or. wood, which by 
glues, gums, or other resinous substances, 
will be made ‘to adhere to iron; and the 
vessels thus lined, will have all the pro- 
perties of a tivned or wooden vessel. 
He likewise claims, that all aqueducis, 
reservoirs, docks, canals, and all such 
places requiring - invertéd arches, and — 
other sécurities, from | the contact of the 
surrounding earth, or water, may be 
made in the same way, in- the place of 
wood, stone, and brickwork. This he 
dedounnates building m tron; agreeably 
‘td which, he assumes that. strong wares 
hgus és, manutfactories, fortified ‘places, 
Mansions, tombs, churches, &c. &c. may 
he per nmanently built, or erected hy his 
‘method, according to any of the orders of 
architecture, in the place of stones, 
bricks; and other ter raqueous substances,
