The apparatus I have found to be necessary consists of a glass tank, 36 inches long, 17 inches high and 7 inches wide, though I sometimes use a smaller one. I have notches, a little wider than a pane of glass is thick, cut into the frame work at the ends, so that a piece of glass may be slipped into them, thus dividing the tank into halves or fourths, thereby bringing the fish close to that side of the tank which faces the camera. Almost any kind of focusing camera with a speed up to a hundredth of a sec- ond, may be used, but I prefer a Graflex with a Zeiss-Tessar F 4.5 lens, and ex- pose from i-ioo up to 1-265 of a second, the light governing the speed used.

Other accessories should consist of a tripod, folding table on which to place the tank, a bucket or two, small net for removing fish from the tank, a rubber tube to siphon out the water, and a rub ber window scraper with which to kee)' the glass sides and partition free froii bubbles and drops of water.
