It is argued that previous experiments investigating interocular transfer of adaptation have been concerned with an adaptation of the registered position of the limb used to indicate direction. Thus the question of interocular transfer of adaptation sited at the eye remains open. Two experiments are reported. The first showed that there was complete transfer between exposed and unexposed eyes. The conditions were such that the adaptation could be explained only as a change in the registered position of the eye in the head, or of the head on the shoulders. The second experiment showed that changes of this latter kind did not occur.
