122 Tmnsadions of S.M.P.E., May 1924 in the speed pictures the figure was one-ninth of the distance from the camera of the others, we would get a very convincing representation of a giant of nine times normal stature. Summary After outlining the uses of mechanical miniatures in cinematograph}', rules and laws governing their use are derived from the fundamental laws of dynamics and the theory of dimensions. These rules are: (1) Where the principal forces are the weights, all linear dimensions appear to be magnified as the square of the -magnification of time. (2) Where forces other than weights are involved they should be scaled to the same proportion as the weights and then the above rule still holds. (3) In a miniature built exactly to scale strengths of materials should be scaled down in the same measure as the dimensions. The application of these rules in cases where human beings are in the scene is discussed and the way in which a normal man might be used as a "working model" of a giant is pointed out.
