Theiris formed a narrow band at the sclero-cornealmargin, with no points of adhesion, giving aperfectly round pupil. With this condition, the examination of thefundus was a matter of comparative ease. By the direct method, the first noticeablefact was a fine black line extending in a directcourse from the inner side of the optic disc tothe nasal side of the vitreous chamber. Thisline seemed not to lie directly on the retinalsurface, but anterior to it. Following this linefrom within outward as I approached the opticnerve, I found a condition which I have triedto represent in the accompanying The black spot marked R, I take to be a rup-ture in a blood vessel, which has elevated apoition of the retina, which I have tried torepresent by the semi transparent white space,somewhat triangular in shape. Why this condition should exist in the pos-terior aspect of the globe from an injury re-ceived on its anterior surface, is a very interest-ing point. It is quite convincing to my mindthat it is due to the so called contre a blow on one side of the cranium some-times causes a fracture on the opposite side, thesame condition may come about in the eye-ball. If the history of this case is correct, the re-tinal disturbance is not at a point directly op-posite to the point receiving the blow. Thisresult may be due to two causes—I. As I haveintimated, an incorrect history; and 2. To thefact that the currents of force, in passing aroundthe globe, in opposite direction, one met withmore resistance than the other, necessarily re-tarding its progres
