probable that, with the powers he pof-

degree of excellence as he actually did in

I have faid thus much of Morland, not 
‘with a view to depreciate his talents, or 
to perpetuate the memory of his faults ; 
but becauie, though ail have been loud 
in his praife, tew have Judly appreciated 
his talents; and though all have cenfured 
his irregularities, no one has truly fhewn 
whence they proceeded: and I hope this 
fketch will not have been made in vain, 
if it farnifhes an additional proof, that no

NEW PATENTS LATELY ENROLLED, 
MR. GEORGE ALDERSON’S (CARNABY- 
STREET), for a new-invented Manu- 
Jaciure of Metal Pipes. 
HE manufa&ture of - thefe pipes, 
which are made of lead, and lined 
with tin, is thus defcribed :—Moulds are 
provided of metal or wood of different 
lengths and diameters, according to the 
length and fubfance of the pipes to be 
manufactured. Thefe moulds are in two 
pieces, divided longitudinally, and are 
nearly fimilar to thofe generally ufed by 
plumbers. They are attached to the 
ground, ina vertical fituation, by fcrews 
and wedges ; and into the centre of the 
moulds is introduced a moveable polifhed 
iron rod, maundrell, or core, the lower 
end of which goes, with a fhoulder, intoa 
hole made to receive it in the bottom of 
the mould, and the upper end terminates 
a few inches above the top of the mould 
in the fhape of a hook orring. This iron 
rod, maundrelJ, or core, is made of fuch 
a fize as to leave a {pace all round between 
it and the mould, fufficiently large to re- 
ceive the fufed metal to form the pipe. A 
{mall collar is made near the top of the 
maundrell, to keep it in the centre of the 
mould, with two holes made in it; one 
to pour in the melted metal, and the other 
for the air to efcape. As foon as the 
melted metal is poured in and fet, the 
maundrell is pulled out by means of pul- 
lics, or Jevers, or any other contrivances, 
and another, but {maller one, is fubfti- 
tuted in its plece; leaving a fpace fufi-, 
cicntly large to receive the melted tin all 
round between the newly intreduced 
maundrel! and the lead or metal already 
calt. A fmall] quantity of refin is then 
thrown in, which melis and runs to the 
bottom ; the melted tin is then poured in, 
and; as the tin rifes, the refin rifles, and 
ais as a flux to unite the metals. When 
the tin is fet, the maundrell is to be taken 
away, the external mould is opened, and 
the pipe knocked out, which is then, as 
foon as it is cold, fit for drawing. 
This operation, the patentee juftly ob- 
ferves, may be reverfed ; that is, the tin 
pipe caft firft upon a fmall core, and that 
being removed to a larger mould, the 
lead to be caft round it; or the tin pipe 
need not be caft on purpofe, but may be 
cait and drawn, or foluered and drawn,.to 
any length, and afterwards cut into the 
length of the moulds, made perfeéily 
clean, and the lead be caft upon it. 
When the fhort thick caft pipe is pro- 
duced, it muft be drawn to the proper 
length and fubflance by any of the com- 
mon and well known procefles, but mutt 
have a polifhed metal rod, for the purpofe 
of keeping open, prelerving and perfect- 
ing the infide of the pipe, which rod mutt 
be afterwards drawn out. eit 
Lead pipes may alfo he lined with tin, 
by drawing the tin pipe to the required 
thicknefs on a rod or maundreil, and then 
inferiting the rod, with the tin upon it, 
into a lead pipe already drawn, which is 
but ju large enough to receive it, and 
affing the whole through a collar or two; 
which, by diminifhing the diameter of the 
iead pipe, will burnifh or prefs it on to
