Abstract
THE use of the.kinema for schools, and not merely for school children, has been definitely carried a few stages nearer realisation by two recent developments which were brought to the notice of teachers attending the annual meeting of the Geographical Association. In the first place, a portable instrument at the fairly reasonable price of 6oZ. is now on the market. The case itself is fireproof; the lamp is in one separate fireproof chamber within the case, and the film is con, tained in another, all except the four inches or so actually in the gate; while the instrument is operated by pressing two or three buttons on the outside. The adaptation of the kinema to the class-room in this way has two incidental advantages which are in themselves very great advances. Owing to the fact that the light required is not nearly so strong as for a halj, (j) the instrument. can be run off one of the lighting points in the ordinary lighting circuit, and (2),the reduction in light is accompanied by a reduction in heat, so that the film can actually be stopped for some minutes for discussion by the class.
