|a The combination of color schlieren with high speed flash techniques has proved to be a valuable tool for investigating high speed transient events. Fully two dimensional refractive index information can be ob tained. The resolution on 35 mm film was sharp enough to allow 50 cm by 75 cm color enlargements. REFERENCES 1.

I notice that in two of his pic tures density gradients in directions at right angles are shown by the same colour transitions. MY' J Kim Vandiver: The photographs presented were not composed to yield accurate determination of the direction of density gradients
