10 include in this medical enquiry at least two
Scotch physicians There are several Scottish
medical men in this city who hold positions
of responsibility and in whom the public would con-
hide, and who alone, IN the opinions OF all who
give moments reflection 10 this painful case, can
be deemed adequate 10 the task imposed at present
on these, altogether incompetent. Come now, let
us have this matter properly arranged. Let this
poor creature, now lying in prison, have female
attendant and let Drs. Caldwell and Cumming, or
two other equally intelligent and respectable Scot
fish physicians, if they at hand be added TO the
commission entrusted with the duty OF ascertainlng
the mental condition Of this unfortunate person.
CRoToN WATER PpRs.-lt very rarely occurs that
an article can be offered to the public, very greatly
improved in quality, and at much less price thanit
has ever been manufactured for before. Yet this is
now accomplished, and in an article too, OF enor'
nous consumption at the present moment, in which
all landlords greatly interested, namely, in lead
pipe for the conveyance of the Croton water.
When the mode of making pipe in long lengths
by perpendicular pressure was introduced, the
process was considered the achme of perfection,
because it was thought that the column of melted
metal had its atoms thus considerably compressed,
which rendered 1t more compact, and OF course
more capable of additional resistance. The fact
was overlooked that the lower part of the column,
from its specific gravity, would be much denser
than the upper part of it, which would be subject
to the extrinsic pressure only, and consequently
that sucn pipe could not bear an equal pressure
throughout the whole extent of its length, because
unequal in density, which in practice proves to be
the case.
Still, however, II was an Improvement on the an
Gent method of drawing lead pipe, which has
tendency to separate its PARTICLES, instead of bring
ing them into closer contact.
Science has recently, however, carried that i'm
provement to peint of perfection never before
hoped for anticipated, whilst the cost of the arti
Gle to the consumer is now materially diminished.
A few days since we inspected machine which
has been lately patented by gentleman in this city,
and is now In full operation, and WE believe that
description of its operation will not be unnteresting
A bar Of cold metal passes successfully through
three of grooved cylinders, being thus gradually
brought down to the size of the pipe required. AS
it proceeds each separate atom encounters regu-
lar and even pressure OF several hundred tons
throughout its whole length 1t thus acquires an
equal density in its formation, hitherto unattainabe,
and consequently very great additional strength and
durability, whilst the interior surface becomes es
highly polished as a mirror.
A piece of this pipe was attached to the hydrau-
c pump which withstood pressure of 26OO lbs. on
the square inch, without the least shadow of a
swell, whilst similar piece of hydraulic pressure
lead pipe begant to swell at 1900 lbs. This was tole
rable proof of its superior density and strength
Many persons may possibly say, well, as the
average pressure of the Croton water is not above
SO lbs on the square inch, pipe that will stand
1900 lbs will answer every purpose, not taking the
difference of price into account This is mis-
ake Lad NJ hitherto ms de has heeu ncs
pable Of sustaining the conclusive shock of the n.y.
drants Most of them have burst, and in some 10
callties more than once.
We have not calculated the exact pressure which
takes place on all such occasions, as that depends
on the size of the mains, and the length and dame
ter of the service pipes but the average, it is
evidently above 1000 lbs per square inch and Ser
re's pipe sustains pressure of 600 lbs per square
inch more than this, without the least indication of
change
Another serious defect attendant on pipe made
by perpendicular pressure, in state Of fusion is
that IN order to form the bore, 1t has to pass the
lateral supporters of short core or mandrl,
which cuts it ongitudinally into several slips or
pieces. These have to unite again in semi-fuid
state before it can become pipe. Now these
strips sometimes imperfectly cohere that plug
VIII often split the pipe al the very Jennings.
Scrolls pipe, on the contrary, remains entire
through the whole process, and therefore free
from such defects Indeed a virtue the very re-
verse accompanies it, each pair of rollers it
passes between brings Its atoms into hrmer and
closer contact. The excessive density thus pro-
duced is easily proved. Let any one cut the ends
of both pipes with knife He will find it easy to
pair offa shaving from the hydraulic pressure pipe,
the substance of which is comparatively soft, but
difficult TO perform the same operation upon Ser
rill's the metal being much closer in its texture |
and more condensed
On all the grounds we have mentioned, we are
disposed to regard the new pipes as much preiera-
bic to those made by the old process, and therefore
commend them to public attention.
