MOVING PICTURES 



THE SEA BOTTOM IN MOVING PICTURES 



The method employed in securing pictures of life near the coasts, where the water is about fifty 

 feet deep. The operator sits in the space at the bottom of the collapsible tube which extends down-

lowed. One film shows the effect of a bullet 

 striking a suspended rubber ball filled with 

 water; another shows the effect of a high- 

 velocity bullet striking a bone and shattering it. 



Moving Pictures in Medicine and Surgery. 

 During the last few years the use of moving 

 pictures by physicians and surgeons has been 

 greatly extended. By combining the micro- 

 scope, the ultra-microscope and the "rapid-fire" 

 camera, the most minute microbes have been 

 studied. By combining the X-ray machine with 

 the moving-picture camera equally striking re- 

 sults have been obtained. The processes of 

 digestion in a frog, in a fowl, in a lizard and in 

 a trout have been photographed; also the proc- 

 esses of the human body, showing the bending 

 of the knee, the opening of the hand, and the 

 like. In addition, great surgeons have been 

 photographed performing some very delicate 

 and difficult operations, such as bone grafting, 

 and this film is available for, other surgeons to 

 study. 



Industry and Moving Pictures. Frank B. Gil- 

 breth, of New York, an authority on workshop 

 organization, is perfecting scientific manage- 

 ment through motion pictures. By means of an 

 elaborate mechanism, Mr. Gilbreth is able to 

 photograph all the motions made by a work- 

 man in doing a particular piece of work. These 



pictures are not made to be projected on a large 

 screen, but are studied under a microscope with 

 a view to discovering waste motions and later 

 reducing all the workman's movements to a 

 minimum. Some of these pictures were made 

 by attaching an electric light bulb to the opera- 

 tor's head and hands and studying the photo- 

 graphed paths of light. Other pictures have 

 been developed for the benefit of apprentices. 

 An apprentice is shown, step by step, the 

 movements made by the most skilled workman 

 in the shop; experience has demonstrated that 

 a youth can learn his craft more quickly by 

 following it on the screen than by observing 

 the actual work. This is due to the fact that 

 many of the movements of a skilled workman 

 cannot be followed with the naked eye. Once 

 these movements have been photographed, 

 however, the camera projects them at a rate 

 slow enough to be studied. 



Moving Picture Targets. Another interesting 

 use that has been made of moving pictures has 

 been in improving marksmanship. The motion 

 picture had scarcely been perfected when the 

 war departments of the various countries were 

 flooded with suggestions for making this use 

 of them, but the animated target has not yet 

 been extensively used by military authorities. 

 The idea is as follows: Instead of using the
