Some of the cases recorded might well ha vm been accompanied by dislocation of the lens, by haemorrhage in or detachment of the retina, by crushing of the optic nerve in the optic foramen, and by other conditions which the inven- tion of the ophthalmoscope would now enable us readily to diagnose, and which can in no way be regarded as of a reflex nature. In one case, for example, the patient was thrown out of a wagon, and in another severely pecked by a turkey-cock.
