BITUMEXISED PAM TUBING.

Yesterday an experiment was made under the
peat Cloak Tower, Westminster, for the purpose of testing
the strength, by hydraulic pressure, of a novel descriptios of
tubing, composed of bitumetieed paper, invested by Y.
Jalonrean, of Perla. M. J slowest ie a contractor for paving
Perin, end other large towns of France, with bituminous oon-
Crete. la the course of his experiment* Poore piper which
bed been coated with bitumen was laid aside in • coiled form,
and after geom . time it assumed a very stiff and solid shape.
Pursuing the idea whist ac. ideatthw developed, M. Jelourean
put several layers of hitumenised paper round • cylinder, and
submitting them to internal pressure, be found that • tube a
I inch in thickness was °spank of misting a pressure of
i..501be. to the square inch. The lightness of them tube',
their portability, their cheapness, and their non-liability to
oxidation Induced the municipal authorities of Paris to try
them fur the col:moven°, of pa., and in the experiment' of
yesterday a piece a[ tube was produced, which, though stated
to have been under ground In Paris is a gee pipe for twelve
months, had the appearance of being • perfectly
new pipe. The tuber subjected to the preesure of
the hydraulic pump yeeterday bore • strain of MO lbe. to the
square inch without bursting, which is mom than they
would be mew called on to beer in ordinary me, being equal
to 650 feet bead of water. One of the tube., half-an-inch
thick, sad with • bore of two Mabee, wee also tested by
weight, and It only gave way to it pressure of 428 Its., the
beams' being three Met apart. Mr. buiiib. Mg. Hughes,
Mr. Dingle:, Mr. Braithwaite, Mr. Dennis, aid other
tingietiers, who wets present, expressed themselves entirely
satisfied with the experiments, and considered that they
might be substituted with advantage in many cases wnere
iron tubes wore now used. As to their meltability of resisting

perature of 160 degrees of Fahrenheit without any detente.

Mon of price is a main ingredient in the practical value of all
these invention.; and in this view we undnstaad the new
tubing hes • decided superiority, as its coat is not one-half
that of the “rdintiry iron piping. Messrs. Paul /Tooke sod
Alexander Young are the patentees of the invention in this
country.
