Wnetner cOlors match was announced
yesterday before the American Chem
ical Society.
The device is expected to put an end
to disputes between dressmakers al
their customers over the matching of
materials. The husband who is sent to
obtain a certain shade of turkey red"
hereafter will be helped by the new
machine, and lawsuits which have
arisen over the claims of debutante
that her gown was transformed into an
unbecoming color by the dyer may lie
settled out of court.
For years, 1t was announced before
the chemists at their convention at
Columbia University yesterday, scien-
lists have sought mechanism means
of matching colors and registering de-
grees Of shades A demonstration with
model made by DR.. Alexander Lowry
and DR.. Oswald Blackwood, Of the Uni
versity of Pittsburgh, was received ss
one of sciences latest achievements.
1t Has Name
The instrument is known as a.
selenium galvanometric colorimeter.
it's inventors. is to be in the testing Of
dyes. 1t will determine any difference
in shade between a silk thread and a
ribbon which to the unaided eye appear
identical in color.
An explanation of the operation of
the machine necessarily is technical,
but in brief it may be described as
throwing a beam of light from each of
two samples of colors through distilled
water and other solutions on to the
galvanometer, which registers any diff
ference.
Some of the chemists declare that
the colorimeter ultimately will be used
for registering compilations.
Discussion of scores of subjects was
heard by the 5000 visiting chemists,
who will close their session to-day with
an inspection of the city's industries.
Anthrax, which annually causes many
deaths in this country, is spread large
ly by, shaving brushes, according to
Aldred Seym our-Jones. "Like many
other Diseases" he said, "anthrax is
caused by a organism. 1t is ex-
tremely deadly to humans and animals
alike. 1t is not a disease indigenous
to the United States nor to Great Brit
ain, and is imported. in materials such
as hair. bristles, wool and dried hides
and skins, mainly from Far Eastern
countries. Since it is imported, it is
possible to prevent its entry into our
countries and so save many lives an
nually."
Plea for Metric System
A plea that the metric system be in
PRODUCED in American universities and
colleges was made by Professor Eugene
3. Bingham, of Lafayette College, Eas-
ton, Pa. He declared that one hundred
institutions had voted in favor of the
system.
Reports of high mileage results with
gasoline were described as being due to
"hot air" by Professor George G. Brown,
of the University of Michigan.
"By introducing hot air into the car
buretor directly off the exhaust" said
DR.. Brown, eve automatically get
ment with the type of carburetor which
can be adjusted from che drivers seat
has shown our ability to get from
thirtyfve to forty miles gallon on
level runs. In these experiments a hot
air attachment was used.
"We have perfected carburetor
which automatically adjusts itself as
the car goes UP or down hill, and we
are demonstrating practically COM
plete saving of the 80 per cent of power
wasted in the old style carburetor. and
are getting for I'D and down hill driv-
ing nearly uniform mileage better
than, forty a Gallon.
Produces Forty-f1ve Miles
"The new carburetor is producing
forty-five miles and holding that mile
age over country runs involving up and
down hill travel"
Economy in the saving of millions Of
dollars through the recovery of pc
troleum which has become mixed with
water in oil wells was reported to be
under way by DR.. Sidney Born. of Mus
kogee, Okla. c. r. De Long, chief chem
list Of the United States Tariff Commits
sion, declared that artificial camphor
is being made in large quantities in
this country from coal tar.
DR.. Edgar F. Smith, president of the
society, and c. A. Browne, chairman of
the Priest1y memorial committee, at
session held in the Columbia gym
SUM last night announced that a por-
trait of Joseph Priestly, the discoverer
of oxygen, had been presented to the
National Museum at Washington.
