Demonstrates various methods of preparing materials to be used on different types of still projectors. Explains that instructional materials may be prepared for projection by utilizing their qualities of opacity, translucency, and transparency. Shows the use of carbon film, adhesive coloring materials, India ink, and sheets of plastic. Demonstrates a technique for stenciling on carbon film and a method for making plastic transparencies from magazine pictures.
**WARNING: CONTAINS GRAPHIC IMAGES OF LAB TEST ANIMALS** Illustrates the basic techniques of obtaining germfree environment, germfree animals, and methods of germfree miantenance. Demonstrates the methods by which germfree animals may be obtained as with the chick from the egg and a guinea pig from a Cesarian operation. Concludes that thee techniques contribute in the field of immunilogical studies and in the study of tissue response to parasites.
Describes the states of Texas, Louisiana, Mississippi, Alabama, and Florida as comprising the Gulf Coast region of the United States. Picture crops in Florida and explains that these crops are grown twelve months of the year. Contrast the varieties of soils found in the region. Briefly describes the large ports of Houston and New Orleans. Highlights the industires of the region including oil, grazing, and lumbering.
Illustrates abnormalities in gait caused by pain, structural defects and deformities, neuromuscular disorders, and a combination of these causes. Details technical symptoms of the gait and posture resulting from poliomyelitis, spastic paralysis, hypotrolic muscular dystrophy, distonia musculora, and dislocation of the hip, indicating the results of the Trendenburg, flexion, and other tests. Presents Dr. William T. Green of Harvard Medical School providing the narration for the examples and conducting the physical examination for each case stressing that careful observation of the gait is one of the key factors in diagnosis.
Do you like to live in a city? Or would you prefer to move to the suburbs and escape slums, juvenile delinquency traffic jams? Many people are moving to suburbs, and urban areas are growing until, on the east coast, there is in effect one continuous urban areas stretching from Washington, DC to Boston, Massachusetts. What can be done to reclaim the slums? How can industry be attracted back to an area it has deserted? The story of the development of the East Liberty area of Pittsburgh is told in detail, showing how effective private citizens can be if they wish. Once again other information on the solution offered by different groups and communities is made available –though much of the material in this program echoes comments and data from the previous program. But this, again, is an effective plea for the citizens’ concern for his community.
Demonstrates the use of high contrast photography for the preparation of 2" x 2" and 3 1/4" x 4" negative and positive slides, transparencies, and overlays for overhead projectors and for printing on paper for use in opaque projectors. Shows the basic steps of setting up to photograph materials on high contrast film as well as the processing of the film. Illustrates the application of this type of photography in the preparation of instructional materials in a variety of subject-matter areas.
Demonstrates the production and utilization of seven types of 3 1/4" x 4" handmade slides by teachers and pupils in various school situations. Stresses sources of picture material and special production techniques, such as the placement of the copy, its size, the use of a margin guide, and binding techniques.

Reviews the contributions of Mendel, the Hertwigs, and Miescher to our understanding of modern genetics. Discusses chromosome chemistry in terms of the cytological distribution of nucleic acids, the chemical composition of chromosomes in groups of isolated nuclei and in single nuclei the chemical content of salivary chromosomes and their bands. Compares cell activity with the DNA and RNA content of various giant chromosomes in insect larvae which leads to the conclusion that gene action can occur by the disproportionate increase in the amount of DNA or RNA. Lecture given by Dr. J. Schultz.
