•' Stirling, January 25, 1850.

" I have great pleasure In informing you that I had a trial to-day
of the I!4 -inch gutta pereha tube I had from you in December last,
in preitnce of a Committee of the Town Council, who were highly
pleased with the experiment, and have resolved to have 400 feet of
the same for attaching to our fire-plugs for extinguishing fires, and
watering the streets in dry weather. lam of opinion.that no mate-
, rial is so well fitted for the above purpose as the gutta pereha, for
although our pressure is perhaps the greatest in the kingdom, being
upwards of 450 feet, not the slightest effect could be discovered on
the tube or joints, while the same pressure on our leather hose sends
the'rivets in all directions.—l am, your obedient Servant,
"ANDREW ROBERTSON."

" Gentlemen,—Without reference to the -variety of useful and or-
namental purposes to which gutta percha is adapted, I consider it in
a sanitary point of view to be a most fortunate and important dis-
covery. I have already (from a sole regard to the public benefit)
certified my decided approval of it for the under soles of shoes, and I
have only to add that I find it equally well applied to walking or dress
shoes and hoots by your agents. As the supply of pure water is so es-
sential to health, and leaden pipes and cisterns are so objectionable,

I cannot too lfghly recommend the gutta percha for-tubing and
lining. .. _

" I am, gentlemen, your humble servant,
"J. TAYLOR GORDON."

" POrtiandiplaee, Hull, March 28, 1850.
" Gentlemen,—lt is impossible to conceive of anything more in-
jurious and destructive to the health of the community than the use
ofleaden pipes for the conveyance of water. The poisonous salts of
lead thereby communicated are most insiduous and subtile. I hall
with gratitude the substitution of gutta percha tubing. I have had
the leaden pipe of my own house removed and supplied by one of
gutta percha.
" I am, respectfully, Gentlemen, your obedient servant,
"J. S,IJRRAY, PH. D."

In consequence of improved machinery, whereby a continuous
supply of gutty percha is maintained, the Gutta Percha Company are
enabled to supply the tubing in much greater lengths than formerly.
