Abstract : A system of classification of the shapes of meteor echoes is established, and a recording on punch cards of this classification with data on the meteors' physical properties is described. A simple velocity-computation method is described, and a number of statistical relations of shapes and physical properties are computed. The survey covers about 1000 meteors with a comprehensive study of all echo types. It shows some characteristics of the stations and selection effects in the established reduction program. (Author)
