Washington, July 3O.-An artist who
paints queer, interesting pictures ~
Leonard H. Wilder of the public health
service. A water color painting OF
grains of dust so highly magnified tnat
YOU can see the sharp edges OF some
grains and the jagged. saw-hke cages
Of others is one of his latest WORKS;
A different style of art is represented
by a pen and ink drawing on MS stuolo
wall, showing a cross section or a stia"
tick with myriads of parasites s"im-
ming in its blood.
All about the wall hang other eX-
amples of the scientific artist S shiIl.
They are not the sort of pictures MAJ
you would buy to hang IN the parlor'
but they are painted. many OF the"'
for the benefit Of the public.

newest art works have been sent TO
RIO de .Japeiro to the centennial ex-
position. Some Of them. painted on
glass. represent a new development
in scientific art.
Using a Microscope
A microscope has always been re-
garded as the most lucid way OF snow
ing scientific wonders to the pubic
But if you have ever been offered Il

iect on the plate is rarely satisfactory.
Even a person accustomed TO using sci
entific apparatus may have difficulty In
focusing the instrument. Mr.. Wider
saws that he never likes to use any
microscope except his own. because
it takes several days to get used TO q
strange instrument. even If 1t IS or the
same make and type as his own. 50 II
is not strange that the public, offered
a Quick view of Il few interesting germs
ut some exhibition. rarely gets q good
look. Nothing. however. seemed so
convincing to the layman as a micro
scopic plate, and the public health
service often packed and sent out 10
instruments to health exhibitions.
A few months ago, though. Mr.. Wild
er experimental with some water color
paintings of parasites on t~lve-inch
squares of glass. Each of these was
put in the bottom of a fairly deep box
and a glass cover was fitted on the TOP.
The result was a view that stood out
in relief just as the microscopic plate
did, and the painting was larger and
did not have 10 be squinted at or
brought into focus. The Transparent
cies went to an exhibition in Chicago
and doctors and other visitors approved
of them highly.
Among the glass paintings sent TO
Rio de Janeiro are a number OF pie
lures showing the dangers Of dust. Mr..
Wilder went into the street and got
some samples that he thought typical
of municipal dust. He magnified them
highly and painted them on glass.
Seven-eighths Of the grains had cut
ring edges. The grains with sharp edges
like glass were crystalline products.
probably the finest sand. Cinders were
in the dust too. and the microscope
showed that they had saw-like edges. in
furious to the ears and eyes. 1t took
a microscope charging the dust 900
times to show clearly the character OF
ordinary dust. The moral was so obvious
that il was scarcely necessary to write
on the label n plea for cleanliness. The
sharp grains. tiny ss they are. may do
damage to the lungs and leave them
susceptible 10 the attacks Of germs.
For another picture. Mr.. Wilder took
a tiny piece of cotton from the floor
of a cotton mill and a piece of wool.
He leased them out to the finest pos
sible condition and magnifed them. The
resulting picture showed that in these
fine leased fibers there was a certain
amount of organic matter which. If
taken INTO the system OF II human DP-
ing. would cause serious inconvenience.
fine atoms Of cotton and wool
are breathed in by workers in mills.
He also made a picture of flour dust
which blows about in the air of a flour
mill. His picture showed that this flour
dust which falls on the floor and then
blows up into the dry air is largely i'm
pregnated with organic matter. The
pictures of dust were all sent
to Rio 10 show the people that such
may be dangerous unless

Artists Varied Career
