These views are sufficiently refuted, first by the fact, that this transposition, as it has been erroneously termed, of the most acutely seeing point of the retina to some other point, is very rare, and altogether exceptional; and secondly, by the fact, that when such a condition of things is met with, the rectification of the position of the eye does not alter them. In the case just related, it will be observed that although the squinting eye had been completely rectified by the operation, and although the sound one had been bound up for two hours daily, for three months, still the abnormal point of most acute sensation, had neither been transferred to any other point of the retina; nor had the visual
