546 CINEMATOGRAPHIC ANNUAL slowly that the human eye cannot perceive them. By taking single exposures at time intervals, for instance 1, 2 or 3 per minute, and by showing them through the projector at normal speed, 16 per second, the motion of these cells are translated into understandable speeds. These are just a few possibilities for microscopic motion pictures, but the fact is that the field of adventure in this world of wonders is unlimited. In order to give the owner of a 16 mm. camera the opportunity to take motion pictures through the microscope, the author has designed a little apparatus (Fig. 1), which is the result of many years of experience in this field. The microscope (any make) is placed on the base plate and brought in line with the center of the opening of the camera holder, which is screwed without the lens on the swivel plate, to the left so that the focusing lens is in line with the microscope. After the object is sharp in focus and the beam of light adjusted properly by looking into the ground glass, the camera is swung back in position and the picture can now be taken. By using a so-called beam splitter the object can be observed while the picture is being taken. All this is made so easy with this outfit that anyone can take microscopic motion pictures without difficulty. Any make of camera can be used with this apparatus, be it hand or motor driven. Fig. 1.
