INDIA RUBBER.


India rubber, also called caoutchouc elastic resi-
produced from the syringe tree of Cayenne and othe
parts Of South America. 1t Is found in abundance in Pc.
ra the Bazs and in Quito. OF late years consider
able quantities have been brought from Penang Sngt
pore and Assam but of inferior quality, being mixed
with nearly thirty per cent Of sand and bark. The
ceoutchouc Of Para is the most pure and r that port

Numerous inventions have been made in connection
with India rubber and at the present Is applied
bly, TO purposes than almost any other material
The first application of caouehouc 70 extensive
TO have been made by Mr.. Barnard VINO twenty two
years ago paten ed kind Of liquid India rubber which
be elastic vainish for rendering clothing
other things waterproof and called caoutchesine. The
next inn ortant patent the for making
proof gar ments taken out by Mr.. Mackintosh, Of lss
Cow whose has become familiar In conneco with
the material. Mr.. Mackinto his m sthod Of making his
waterproof cloth exceedingly simple. The India ruboer
Is dissolved In the oil distilled from gas tar and spread
upon the surface OF piece of CLOTH upon which similar
ece Of cloth EXTENDED both pieces then pressed
between couple Of rofers Hence the waterproof cloth
consists of pieces of cloth united by intervening
layer Of csoutchouc.

IL the process of vucanation process which consists
combining in certain way caoutchouc and sulphur.

rubber cannot be effected by Any known solvent Il Is
