BLOOD PHOTOGRAPHS.
A New Invention for the Aid Of
Physicians.
Pictures of the Circulation Similar
to Those Used in the Kinets-
soOpe-Description OF the
Apparatus.

The action and rapid changes in cell
life can now be photographed, as
horse race or prize fight, for out OF the
microscope DR.. Robert L. Watkins, of
New York, has evolved the micro-kin-
etoscope, or as he calls it, the micro
microscope. This apparatus will great
~ enlarge the use of the microscope and
will give to the micro-organic world a
new interest and fascination, for photo
graphs of all sorts of cell motion OBJ
served in tile microscopic fluid can be
taken, remagnitied thousands of times
and thrown upon screen, where they
may be studied in clearest detail.
The value of such an apparatus to
science at this time is of very great i'm
portance, for the whole world of biol
ogy, physiology and medicine has en-
tered upon the study of all cell life Of
blood and of bacteria, with a keen
sense of their value in explaining life
and disease.
Blood freshly drawn has been photo
graphcd with all it's changes.
No blood has ever been photographed
in actual circulation, except series Of

frogs foot. This picture was taken at
about the rate of 1000 per minute and
when pictures were thrown on the
screen all the changes going on in the
cells and serum were Plainly seen and
all the observations of changes in drawn
blood were confirmed. If living tissue
can be seen with the microscope, and
there are some Of the best of reasons for
believing that it can, the micro-moto-
scope viii become invaluable.
But in the sphere of bacteriology it
will certainly open new and wonder
full world. The study OF bacteria aside
from their connection with disease is of
absorbing interest, for it has been
shown from number of reliab expert
ments made by such men as k!ebs,
Dusany and others that many Of these

fear, etc, that is surprising. Their ac-
tions under such conditions have never
been photographed. The pictures in
the books show only the stained dead
ones, and psychologists have long
been accustomed to speak of bacteria as
without motion, but this is incorrect, as
las lately been shown. Some families
under stimulus move with the swiftness
of flies and mosquitoes.
The apparatus and the method de-
vised for photographing are very sim
pie. A gelatine film so feet long is
wound on wheel of about Is inches
diameter. Cleared to this wheel is Il
little machine is hooded by a box in
which, just opposite the revolving
film and on a direct line with the lever
of the microscope, is small window
At the other end of the lens, lying in d
horizontal plane, is concentrated a
strong beam of light from an electric
lantern. The apparatus is capable OF
recording from 800 to 1000 figures a
minute. In order to catch the rapid mo-
zion of the blood stream in the vein Of a
frogs foot. it had to be turned to its
full capacity, and the frogs leg was

But the capacity of the apparatus may
be increased by enlarging the size OF
the wheel. The attractions of the lens

Dr.. Watkins was asked az to the value
of the pictures in making diagnoses for
different diseases as shown in the blood
He said that these series Of pictures
taken from time to time in the progress
of a disease or its cure, were of very
great service to physicians memory
Not only that, but blood could be sent
by mail long distances and retain
enough of its characteristics to be in

who do not have the facilities for such
