The rear of the dispensary for diseases of the eye at St. Christopher's Hospital for Children has been partitioned off for the orthoptic department.1 There are six small cubicles, comfortably furnished, making it possible to give instruction to several children at one time. The instruments which my associates and I have found necessary are: (1) a rotating illiterate test chart;2 (2) a Worth deviometer; (3) a synoptophore; (4) a Keystone outfit; (5) a telebinocular with a small interpupillary distance, used for tracing; (6) an amblyoscope, which we electrified, and (7) a perimeter. Included with the slides for use on the stereoscope are the Hamblin series and a few of the less complicated Wells and Keystone slides, as well as the animated cards and several others. On the synoptophore the Sattler series and the transparent slides are used.
