    Wilbrand are, as Berry points out, far from conclusive as to their chiasmal origin, some of them showing total amaurosis of one eye with ill-defined temporal defect of the other eye. a condition noted by Gowers^ in an undoubted case of primary atrophy in locomotor ataxy. Wilbrand has tabulated twelve cases in which a post-mortem exami- nation revealed the cause of the pressure on the chiasma. In six a tumour w^as found, in one a tubercular nodule, in two a gumma, in one a cyst, in one periostitis, and in one meningitis. Besides these, we have a fracture of the body of the sphenoid in one of Nieden' s cases, a sarcoma of the dura mater covering the body of the sphenoid in Ross's first case, and a tubercular nodule in his second case. In McHardy's case was found a reddish tumour, probably syphilitic, involving the chiasma and tracts. Silcock, at a meeting of the Opthalniological Society, December 10th, 1883, showed a sarcomatous tumour springing from the pituatory fossa and compressing the chiasma. In this case, as far as could be ascertained, there had been no impairment of vision. Before describing my cases, I wish to say 1 am indebted to the courtesy of Dr. Little for Cases 1 and 3, and to Dr. Glascott for Case 4. Case 2 I saw in consultation with Dr. Livy, of Bolton. Case 1.—Peter Eaton, collier, aged 30, married, was seen for the first time on December 28th, 1883. He complained of failure of sight for three months, which had come on about three days after a blow on the back of the head. He did not fall, but was only slightly stunned for a moment, and there was no bleeding from the ear. With the right eye he saw No. 19 Jager, and with the left eye No. 16. The fundi were normal, charts of the visual fields were also normal, and there was no central colour scotoma. The patient is a strong, stout, healthy man, and never had syphilis or any venereal disease. He was ordered strychnine. In February, 1884, the charts were again traced and found normal. In March, right 4 and xV, a very great improvement in three months. Left, 16 as before. In July the strychnine was changed for iodide of potassium in ten grain doses. In October the vision of each eye was as at last exami- nation, but the fields of vision now showed the characteristic defects (Fig. I.). In Left. Fig. I.
