FIRST X-RAY Movies
TO Be SHOWN HERE
Will Show How Bone Fractures
Heal; Give Life Processes
of Minute Organisms

The first moving pictures ever
made by X-ray will be shown here
when Arthur c. Pillsbury, botanis.
and biologist. appears at the city
auditorium Wednesday evening. He
will also give a matinee Thursday
afternoon at Ais.
The apparatus necessary for MAX
ing these pictures is the invention Of
MI. Pillsbury, who has In his labora-
tory instruments for photographing
and X-raying plant life. worth SIS, 900.
Pillsbury's most valued treasure is
the Roentgen-ray apparatus used In
conjunction with a special time-lapsc
camera-the first of its kind to be
successfully used in the United States.
Study Bone Fractures
Herbert Evans. noted University OF
California scientist, who discovered
vitamin E. is one Of the collabora-
tors with Pillsbury. The two scien-
lists recently took motion pictures Of
a rat under X-rayS. The creature
had a fractured paw. Pillsbury
cleverly encased him in a lead tube.
letting his head come out so that 1t
could eat its food from a small plate
placed before it. All this time. the
rat was mounted upon the X-ray
machine.
For days, like this, the rat lived a
life in the X-ray and movie photo
graphing combined machine. The re-
sulting films were calculated to show
Just how the bones Of a fractured
limb heal up.
Tiny plant cells were treated with
chloroform, alcohol and other drugs.
They were then observed and photo
graphed with moving films.
This apparatus will be eventually
used by Pillsbury to investigate can

Use Special Type Gamers
For subjects that do not require
X-ray photographs, a camera with an
automatically controlled shutter snaps
pictures every Is minutes, or at any
other given interval for which 1t is
set. If a flower, for example, BIOS
SONS in a week, photographs would
be taken of it every Is minutes.
After being developed and transferred
to the protector, these pictures are
run off at the regular motion picture
rate, taking about IS seconds to show
on the screen. The ratio may be
ried. but this-a week to IS seconds
is the average.
Pairing this camera with powerful
microscopes, motion pictures can be

cess.
Pictures Life of Insects
The ant, slightly larger than a PIN
head, and the parasite that exists
in large numbers on the body Of the
termite, together with the digestive
apparatus inside II Of the parasites,
have been investigated and photo
graphed by Pillsbury in the course Of
his pioneering experiments.
He has discovered curious powers
of the termite itself. It can, for
example. alter its sex at will. The
termites choose ono of their number
for queen and alter its sex by special
food that makes it thrice the size
of the rest and of another color.
These experiments involved mag
