![feet vision to the left, of this line. When, for example, the right eve is iixed upon a point of light eight feet distant, a second point of light is lost to view when it is moved one inch and a half toward the right in a horizontal line; and precisely the same condition exists for the left eye—i. e., the light is lost one inch and a half to the right of the median line. With the right eye it is not possible to determine the spot of Mariotte —that is, the blind spot in the field corresponding to the en- trance of the o])tic nerve {see. the diagram, p. 29)—since the insensitiveness of the retina in that eye commences at the inner margin of the macnla Intea, and extends to the entire inner half of the retina. With the left eye, that portion of the retina between the optic-nerve entrance and the macula is found normal in sensitiveness; since, when at four feet the left eye is fixed upon a point of light, a second light is clearly perceived as it is moved toward tlie left until it has reached a point about nine inches to the left, where it is lost, to reappear at a point about thirteen inches from the first light. Beyond this point the field has its normal extent. By ophthalmoscopic examination no pathological appear- ances whatever could l)e observed, either in the retina or at either optic papilla, beyond the distortion caused in the left eye by the astigmatism, probably of traumatic origin, as men- tioned above. Be^farks.—I. This case is briefly referred to in Circular Bo. G, S. G. O., 1865, at the bottom of page 15; and Dr. Otis writes us that it will be fully related in the first volume of the Surgical History of the War,’' with the chromo-lithograph of the fungus cerebri. As it must first be presented to Congress and published by the Department, no opportunity was pre- sented us of correcting the history by these notes. The history here presented, therefore, as derived from the patient, must be taken with some caution, since the wound has so severely in- jured his cerebrum. On all points, however, he gave very clear statements'. II. The complete recovery from paralysis (as evinced by his subseqent severe labor), and the almost entire restoration of his mental faculties, are remarkable, especially in view of the probable deep lesion of the brain, both by the primary in- jury and the subsequent fungus cerebri.](https://iiif.wellcomecollection.org/image/b22449887_0128.jp2/full/800%2C/0/default.jpg)
