pected but so far they do not contain full information of the kind sought. It is appreciated at the outset that in this regard television is at present under some handicap in relation to the motion picture. In motion picture production sequences having considerable action are taken by careful choice of the most favorable angles. This necessitates use of lenses which will cover a fair depth of field, the remaining inaccuracies being compensated for by the skill of the cameraman. In television, it has not been found possible as yet to use lenses of the same or equivalent depth of field; hence, it seems reasonable to assume that the cameraman will be forced to choose less favorable angles or risk inexact focus. If the former choice is made, the problem of adequate portrayal of motion becomes much more serious especially if the frame frequency is reduced. It was reported by J. A. Norling of Loucks and Norling Studios, from experience in days of silent pictures when "projected at 16 frames per second, which then was the theoretical projection speed, an animated cartoon thus made showed rather jumpy action but when the frame frequency was increased beyond 16 frames per second . . . this jumpy action became smoothed out." He continues, "I review these matters merely to add emphasis to the need for a higher picture frequency than the 8 to 12 picture frequency employed in 2-frame exposures and with projection speeds of 16 frames per second to 24 frames per second" Commenting on the previous problem (flicker), it was further stated that, for light changes such as prduced by a shutter, for screen illuminations of as much as 12 foot-candles (produced by no film in the projector ) , flicker is apparent at 96 periods per second ( as obtained from a 3bladed shutter) but the correspondent indicated that smooth motion and not flicker was the essential problem if reduction of frame frequency were considered. Mr. D. Fleischer of Fleischer Studios, Inc., stated, "In regard to cartoons, we have found the 24 per second frame frequency the most practical for our use and. as I believe animated cartoons will be an important factor in television, I hope that this will not change in their adaptation to this medium." Mr. W. E. Garity of the Walt Disney Productions stated that the number of drawings used depended on the speed of the motion being photographed and that "for slow movements, a drawing for every frame is necessary." The committee is still expecting more complete answers to its correspondence and hopes to amplify this section of its progress report when and if this information becomes available.

Madison St., Chicago. The swivel lens mount enables the operator to tilt the lens for correcting distortion and creating comic effects. It has the advantage of permitting a substantial angle adjustment in all directions. The mount consists of a lens flange, swivel joint with ring lock and 4x4 inch lens board. It is adaptable for use with most all 3 or 3% inch lenses. The lens is held securely in place when the desired angle is obtained, and it is the work of only a moment to substitute the regular straight mounting when a change is desired. The new mount I patents pending ) will list as a Solar accessory and sell for $5.50 less lens. Agfa Darkroom Outfits Two new Darkroom Outfits designed for developing and printing requirements of amateur photographers have just been announced by Agfa Ansco. Identified as the No. 1A and No. 2A Outfits, the developing kits provide all necessary material for developing and printing, differing from one another in elaborateness and quantity of equipment. Both outfits are entirely made in U. S. A. and are obtainable through all regular photographic dealers, the No. 1A at $2.45 list and the No. 2A at $4.95 list. New Leiea Booklets A new pamphlet has been issued by E. Leitz, Inc., which describes the popular Leitz VIII-S projector. Its various features are outlined and illustrated and in addition, there is information on how to use the VIII-S for micro projection, stereo projection, automatic projection, etc. Another Leitz pamphlet just off the press describes the Models V and VI Synchronized Flash Units. The number of this pamphlet is 1284; the one on the VIII-S Projectors is 1285. Both may be had by writing to E. Leitz, Inc., at 730 Fifth Avenue, New York, N. Y.
