Extract from " 'CTie {ßioscope,"

One of the chief uses of the cinematograph
lies in the fiele! of scientific research, and anything
that will assist in the taking of moving
pictures in any one branch of natural science is
to be welcomed. In micrography the camera
is essentially valuable, but the difficulties in the
way of its general, to say nothing of universal, use
have been many and various. Infinite patience,
labour, expense, and, above all, experience of
both micrography and cinematography, have
been needed to produce records of the living
micro-organism. The general use of the microcamera
has, therefore, been limited, and so
kinemicro-photography has not advanced at the
pace one would have wished. Our foremost
producers have certainly obtained some very
valuable subjects that have without question
been of the greatest use in the development of
science, but it is a fact that the füll field of the
cinematograph's usefulness will not be attained
until the micro-cinematograph is introduced
into every bacteriological and scientific institution
in the country.
IIIS combined arrangement of Kinematograph-Camera and
the Microscope will be found to be at once the most complete
and practical outfit that can be coneeived. Complete
in all its details of efficiency and convenience, and practical
in that the various movements offer a means to anyone with any
knowledge of microscopy of immediately being able to take
a cinematograph film of moving micro-organisms, whether of the
larger infusoria or the smallest bacteria. A knowledge of micrography
is of course essential, because success depends almost entirely on the
correct disposition of the object and the arrangement of the illuminating
' apparatus.
^
Not so necessary is a knowledge of photography, because there are
so many firms now who cater for the development of films, that this
rather tedious process may well be left to the experts who can make a
good negative and know what a good negative should be like and have
the facilities for doing it. On the other hand, so many people prefer
to do their own work, both from motives of interest and as a means of
reserving the results for those whom it may more immediately concern,
that we give a list of the necessary, but simple apparatus for printing
and developing their own films. The actual taking of the film is little
more than ordinary snapshotting, with the extra advantage of being able
to watch the image the whole time that it is being recorded on the film.
The apparatus consists of :—
A—A firmly-built Iron Stand with vertical supports,
for> holding the Camera above the eyepiece of
the Microscope.
B—A Kinematographie Camera.
C—An Optica! Bench.
D—A Motor for running the Kinematographie Camera.
These various parts are hereinafter described in detail, and a study
of the illustration will be helpful in following the descriptions. The
floor space required is 4ft. by lft. 6ins.
