motion pictures through a glass win
dow set in the side of fresh egg and
tracing the changes In the stages OF
Incubation until the heart OF the
chicken Is beating has been demon
strated at the laboratory of DR..
Charles +. Herm. formerly Of the
American Museum of Natural His
tory.
Driven by time clock the camera
automatically flashes strong light
every ten minutes through the glass
window into the interior Of the egg
and snaps a picture. This process
goes on night and day for 33 hours,
ut the end of which time the heart
Of the chick has been formed and
started TO work. The glass window
Is inserted after a section three-quar-
tiers of an inch square has been re-
moved from the shell. The window Is
sealed in place by parafiin, and does
not Interfere with the development OF
the egg In the incubator.
Taking microscopic pictures auto
matically, every ten seconds, every
two minutes, or at any interval de-
sired, this machine can also record
the details of chemical reaction, the
action of white corpuscles and the
growth Of new tissues In the healing OF
wounds, the building up of fine crystals
from solutions. or the gradual changes
inslne the egg Of fish from the
original clear fluid to the fully formed
baby fish,
Operated In an observation night
and day for two and even three weeks,
this camera has made records OF
scores Of biological and chemical proc.
esses hitherto incompletely observed
To Film Cancer Action.
One Of the experiments soon to be
filmed Is that Of placing group OF
healthy cells and group Of cancer
cells together In a solution to show
the attack by the malignant bodies
The camera Is development from ar
earlier type used by Doctor Herm tc
assist DR.. Alexis Carrel In studying
the protecting and healing action OF
white cOrpuscles in wounded tissue
1t Is planned to use the instrument
! for the diagnosis of many obscure
plant diseases.
A series of scientific and educa.
tional films made at Doctor Herm's
laboratory at Pelham was shown al
the Pelham theater to party Of sci
ent'sts and others, including DR.. VII.
ham Firth Wells, biologist of the
state conservation commission, and
George N. Pindar and Harry #. Beers
Of the American Museum of Natural
History.
One of the most interesting of these
films was microscoplcal study of the
ffe cycle of the oyster. This film Is
expected to have practical bearing
m the problem Of fearing oysters artI-
dcially and USING their eggs for seed
