SCIENTIFIC AND EDUCATIONAL,—MICROCINEMATOGRAPH FILMS AND ROENTGENCINEMATOGRAPHY

THOUGH the work of the cinematograph is only in its infancy, the range of its possibilities seems almost boundless. When the target-practice pictures mentioned above were taken, it was said that some of the pictures showed a twelve-inch shell actually in flight. The writer saw these pictures, and while he did not see this point illustrated, possibly due to the breaking and imperfect repairing of the film, the statement can be credited, as it is feasible to see this with the naked eye if the observer is well in the line of flight. Another remarkable instance which illustrates the capabilities and speed of the lens has been cited in the case of a picture which shows a rifle-bullet on the inside of a soap-bubble, from which it was learned that the bubble does not break until the bullet leaves the opposite side from which it entered.

SCENE FROM “WASHINGTON CROSSING THE DELAWARE”

The moving-picture is more and more being used for educational and scientific purposes. It has been used for recruiting, and pictures were taken of the convention at Chicago for use in the national campaign. Pictures showing the methods of teaching in New York schools have been shown in many parts of the country. Dr. William M. Davidson, superintendent of public schools in the District of Columbia, is strongly advocating the passage of a bill now pending before Congress to use the schools as social centers for exhibiting educational moving-pictures. Likewise Superintendent Maxwell is urging their use in the New York public schools. Mr. Edison has very recently been quoted as saying: “I intend to do away with books in the school; that is, I mean to try to do away with school-books. When we get the moving-pictures in the school, the child will be so interested that he will hurry to get there before the bell rings, because it’s the natural way to teach, through the eye. I have half a dozen fellows writing scenari now on A and B.” An eight-year course is being planned which it is expected will be started in Orange, New Jersey, in about a year.

By the use of the moving-picture, the St. Louis Medical Society has recently shown the method of inoculating animals with disease-germs and the effect of the germs on the blood. Circulation of the blood and action of numerous species of bacilli were also illustrated. In a micro-cinematograph film showing the circulation of the blood in a living body, prepared by M. Camandon, a French scientist, and exhibited by MM. Pathe Frères, the London “Nature” states that the white corpuscles of the blood are shown gradually altering their shape and position and fulfilling one of their best-known functions in acting as scavengers and absorbing such abnormal substances as microbes, disease-cells, and granules of inert matter. “By reproducing at a slower pace the changes,” this journal continues, “the cinematograph can assist us to attain a clearer perception of the nature of the alteration as it takes place.... No amount of imagination can supply the clearness and comprehension which actual seeing can give. The cinematograph might well become a most sufficient aid to the teaching of very many biological and especially medical subjects.”

SCENE FROM “THE LAND BEYOND THE SUNSET”

This picture shows the fairies guiding a little newsboy to the land of his dreams.

Utilizing the moving-picture with the microscope has given the layman an insight into a world almost beyond comprehension, and yet this field particularly is only in its infancy. At the recent World’s Hygienic Congress in Washington, the large attendance at the lecture of Dr. Fullerborn of Hamburg, illustrated with microscopic moving-pictures, demonstrated the keen public interest in this subject. The pictures showed the skin of a guinea-pig being shaved, how it was inoculated with the hook-worm, the surgeon cutting out a piece of the skin and preparing his microscope. The remainder of the film showed just how the rapid multiplication of the much-talked-of hook-worm is revealed through the microscope.

The peculiar opaqueness necessary for the X-ray is obtained by administering to a patient, who is in a fasting condition, two ounces of bismuth subcarbonate mixed with two glasses of buttermilk. Many radiographs are then made in rapid succession. These are reduced to cinematographic size and projected upon a screen, giving a very graphic representation of the motions of the stomach during digestion. The films used in this paper were made by Dr. Lewis Gregory Cole, Radiologist to Cornell University Medical College, and were shown at a recent meeting of the American Medical Association, and published in the journal of that society and in the Archives of Roentgen Ray. This procedure is termed “Roentgencinematography” by Kaestle, Rieder, and Rosenthal, to whom Dr. Cole gives much credit for previous work along the same line. In the articles referred to above Dr. Cole advises this method of examination for determining the presence of cancers and ulcers of the stomach.

SCENE FROM “THE STARS AND THE STRIPES”

This picture shows the surrender of the British captain to John Paul Jones in the famous
fight between the Bonhomme Richard and the Serapis. The scene was arranged in the
Edison Studio, the American ship being stationary and the other arranged to run on rollers.

“Photographing time” has a spectacular sound, yet patents were recently issued to the writer which virtually accomplished this. Between the shutter and the film of the moving-picture machine are introduced the marked edges of revolving transparent dials, actuated by clock-movement. The figures in the three dials denote the hour, minute, second, and smaller divisions, and are arranged to come to a prescribed position as the shutter opens. By this means the exact time at which any motion is photographed is imprinted on the different pictures of the film independent of the varying speed of the hand-crank. Such records promise to be most useful in the “scientific management” field and medical pictures, from which comparative time studies can be made from a number of films at the same time or from a single film by reproducing it on the screen in the usual manner.

Over twenty years ago, Mr. Edison stated in his patent specification in referring to his ability to take forty-six photographs per second, “I have also been able to hold the tape at rest for nine tenths of the time.” It was probably not intended to convey the impression that he could take anything approaching ten times the number of pictures, as it is of course necessary to provide for rest periods; but it is significant that very recently a machine has been perfected for portraying such rapid motion as projectiles in flight, etc., which takes the almost inconceivable number of two hundred and fifty pictures per second. Indeed, experiments are in progress which promise even four hundred per second.

Films are also being utilized to show the news of the day. A member of THE CENTURY staff was in Rome last year when the king was fired upon. Two days later, in Perugia, he saw a moving-picture of the king appearing on the balcony of the palace before an enormous crowd assembled to congratulate him on his escape. More recently a London theater which shows the news of the day in motion-pictures is regularly opened and important events are shown on the screen two hours after their occurrence, a promptness approaching that of the press “extra.”
