    still further increased whenever he looked to the right, while, at the same time, the para- lysed eye remained in the centre of the orbit, he appeared for the time affected with bad con- vergent sqviint of the left eye. (See also case 1, p. 10.) These or analogous phenomena, which may always be observed when paralysis affects a single muscle of either eye, render it higlily probable that the inversion of the good eye, in ordinary strabismus, is not due to any mere mal- association of the movements of the two eyes, or because they start from different points, as one author has it; but simply to the effort, exerted by the abductor of the squinting eye, to execute a movement of which it is not capable; or to over- come its shortened or more powerful antagonist. Such an effort is necessarily, through the associa- tion between the two eyes, transferred to the ad- ductor of the opposite or sound eye, and thus causes its inversion. This explanation of the participation of the sound eye in the deformity of its fellow, is also given by ]\Ir. Walton in his work on Ophthalmic Surgery.
