APPARATUS USED IN WORK WITH CAPS A photograph of the apparatus usually used in recording eye movements is given in Fig. 21. The apparatus consists of a stand (or frame), a chin rest, two light sources, and a control panel. The frame consists basically of a large, massive stand. Two metal uprights and the control panel, on which sockets and switches are mounted, are firmly fixed to this stand. On the movable part of the large stand is mounted a metal post ending in a chin rest. The chin rest can be moved vertically; horizontally, it can turn about the axis of the post, and after the desired position has been obtained, it can be firmly fixed.

The mirrors 10 and 11 are square in shape, the first with a side of 1 mm and the second of 2 mm. 1 mm. Filter 12 is made of a single layer of ordinary filter paper and is glued to cylinder 13. The transmitting power of the filter is lowered by coating part ofits surface with glue. 7 mm. 6-0. 7 g. Assembly and preliminary adjustment of the cap are carried out on a rigid model of the eye, and final adjustments are made after experiments on the living eye and the necessary records have been obtained.

Usually, at the beginning of the experiment, the experimenter indicates the limits of the field beyond which the subjectmustnot choose points of fixation. If it comes into contact with the lids, the cap may be detached from the eye or may be displaced so that its suction part is on the cornea, and, worst of all, it may injure the eye. This must always be borne in mind by both experimenter and subject. As a rule the duration of experiments with the cap should not exceed 5 min, and only in rare cases as long as 10-12 min.
