Patents lately Enrolled, 
require it, the eondsnsers are immersed 
jn cold-water baths, as is the worm in the 
■worni.tube in ordinary distillation. This 
Kiode of distillation may Combine all the 
Jenown ad\ai>taiies employed by the dis* 
tiller. Tr.e shafts of the agitators may 
"he readily driven by machinery, and se- 
x’eral connected on any scale, if required. 
The various parts of the apparatus con¬ 
nected by tubes may have these tubes 
cither of a curved or any angular form 
most suitable. In many instances one 
refrigeratory, with its agitator, will be 
found adequate to the purpose. “The 
numerous applications,’^ says the pa¬ 
tentee, “of these improvements, as con¬ 
nected with agitation in a liquid medium, 
coupled with condensation by liquid or 
hydrostatic pressure, and of ready de¬ 
tachment of the several parts of the ap¬ 
paratus, witji other obvious advantages 
it would be needless to detail. VVhere- 
cver they are hmnd applicable to the 
processes of combination and condensa¬ 
tion of gases and vapours applicable to 
the processes of distillation, I claim them 
as my particuhir and individual dis¬ 
covery.” 
JIR. RICHARD /aCKSOn’s, (SOUTKWARK,) 
J'or a Alethod of making the Shanks 
of Anchors and other large bodies of 
Wrought lion, of a similar form, 
so as to add strength and soundness to 
suck bodies. 
The method adopted by Mr. Jackson 
mav be thus described : he takes a solid 
taper core of wrought iron, which is to 
>te nuinufactured of the best scrap or 
figgotted iron to the size wanted, in the 
usual way of heavy smitlfs work, until it 
becomes perfectly solid and sounds The 
core is then laid into bars of feather- 
edged'iron, previously rolled and pre- 
pnied for that purpose, other bars are 
then laid round the core, so as to form 
the sliaiik or other large body of iron, 
and hooped up to keep it together. In 
order to form the si.ape of the shank 
taperetl splices of iron must be used, and 
drove down between the bars to a fine 
splice. Tiie shank, &c. being thus pre¬ 
pared, is fit for the forge, and is then to 
ba manufactured in the ordinary way of 
n.akinii ^liar.ks of anchors, and other 
large, bodies of wrought iron, until is be¬ 
comes one solid and sound body of iron. 
And,by laying up the iron w ith the solid 
core, and making the shank or large body 
of iron, in the form and by the method 
described, it vviil not require so many 
beats were necessary in the 
common mode of manufacturing shanks 
of anchors, or other large bodies of iron. 
The body itself will he more sound, and 
a considerable quantity of iron, coals, 
time, and labour, will also be saved. 
In all large bodies of wrought iron re¬ 
quired to be straight from end to end, 
the solid core should then be straight, 
and the bars of feather-edged iron shoulci 
be used and applied round the same, 
without any splices of iron being neces¬ 
sary. 
This invention, it is confidently said, 
will save a considerable quantity of iron, 
coals, and labour, in the iiianufacturing 
of large bodies of wrought iron, and ma¬ 
terially add to the strength and sound¬ 
ness of the same. For by this method it 
is only necessary to lay up about one- 
tenth more iron tlian the weight will he 
when manufactured. By using the solid 
core for the centre, and the feather-edged 
bars placed round the same, which forms 
a round body of iron before it goes into 
the fire, of nearly the form required when 
manufactured, the whole body only re¬ 
quires a sufficient number of heats to 
w’eld the same together, which is effected 
by full one-tliird less than the number 
required by the old method; and it is a 
well-known fact, that the less the number 
of heats given to wrought iron, the 
stronger it will be. By this method the 
centre part of the body will be perfectly 
sound and entire vvhen the same is finish¬ 
ed, whereas, by the old method, the cen¬ 
tre, being composed of many small pieces, 
and by necessarily passing through the 
fire so often before the whole was manu¬ 
factured, becomes loose and uncon¬ 
nected, and the outside of the shank, 
from the same cause, becomes very much 
impoverished. 
MR. SAMUEL HILl’s, (sERLE STREET, 
LONDON,) for a Method of joining 
Stone Pipes in a more effectual manner 
than had been before discovered. 
I cut, says Mr, Hill, a piece of stone, 
of any length, bore, and external dimen¬ 
sions, into rims or collars, from thence 
I take a collar and join it at the end of 
the pipe, with a cement, the external 
diameter of the pipe being a little smaller 
than the bore of the collar, to allow the 
cement to he between tiie collar and the 
pipe; and 1 put tlie collar only halfway 
on the pipe, the other half projecting to 
receive the pipe that is to be joined to 
the one on which the collar is already 
fixed ; and in this way the pipes and parts 
of pioes are to be cerueiUed cocether.
