    liyperasmia of retiim and o])tic disc witli tortuosity of veins. He finds also durinui; the convulsive stao;e injections of the optic discs, witli tlie arteries larger than usual; whilst Dr. AUbutt has seen at the same period anosmia of the discs corresponding to what is believed to be the state of arterial contraction and consequent amemia within the brain, and hypera3mia in a similar number of cases. Dr. Hu<j!;hlinf]fs Jackson has several times found ana3mia of the discs in the epileptic state. All, however, agree that there is a congested appear- ance of the discs when the fit is over, especially a dilatation of the veins of the retina, which often will persist for some days, and diminish only very gradually. Coincident with this, and also continuing for a variable period, is a general anajmia of the retina. Optic neuritis, choked discs, and atrophy are rare in epilepsy, but Bouchut asserts that there are often in epilepsy atrophies of the choroid, inflammation of the retina, with deposit of pigment, exudations on the retina, and hasmorrhages of it, which evidently depend on this disease. In Chorea there is usually no change; ])ut Dr. Jackson speaks of the optic discs being badly margined, w^ith large and wavy veins, and hyperemia of disc in this disease. Diseasefi of the Spinal Cord are sometimes accom- panied by lesions of the optic nerve or retina. In locomotor ataxy, for instance, these abnormalities are found, and are variously explained by diflerent authors. Bouchut states that in almost all ca^es of locomotor
