CHEMIsTs TO DISCUSS
TANNING PROCESSES.
New processes OF tanning based
on studies Of electrical dischsrees
and other unusual factors win be
G:scussed by the leather chemistry
section Of the American Chemical
Society next month In New York
City.
The notable progress made in
American tanning has gained such
recognition abroad that sessions OF
the section will be attended by the
largest number Of European leather
che mists which has ever come at
one time TO the United States.
Some OF these experts will also
attend the meeting Of the Society
OF Chemical Industry of Great Brit
am, which. after convening with
it's Canadian section. will cross the
border to confer with it's American
branch and to hold a Joint session
with the American Chemical Society.
The leather chemical section OF
the American Chemical Society will
meet at Columbia University on
Sept. Z and s. At it's sessions will
he discussed revolutionary methods
by which the tanning OF hides can
be hastened without the sacrince
o. quality. The saving OF time and
the releasing. Of large sums OF
money from its investment IN raw
material thus would have the ten.
dency to stabilize and. perhaps.
eventually TO lower leather prices
American chemists believe:
One of the marked influences In
the sessions will be that OF Alfred
Seymour Jones, the FIRST presIden-
Of the international Association OF
Leather Trades Chemists. This eN-
tensiVe work in the application or
the microscope 20 leather manufac-
turers have made him world famous.
He has prepared two important
technical papers on tanning. In the
event OF his not being able 10 pe
here in person they will be read
ny his son. Mr.. Frank Leslie Sew
mour-Jones. also a leather cnem,s,
who will in addition read a paper
Of his own.
! Another prominent figure in the
/ leather industry Of Great Britain.
who will address the section. Is
Joseph Turney Wood. He is the
discoverer Of processes Of tanning
in which pancreAtin is used instead
Of the crude and obnoxious mixtures
employed by the old-time Journey

Some Of the noted foreign chem,

How tanning as q science has sd-
Vanced in recent years is shown by
the fact that among those who are
