    Mr. G. had been under severe emotional strain for several years on account of the incurable illness of his mother, had kept late hours and had studied hard. His attack of nervousness and headache had lasted for over six weeks. E. V = f| ; Hm 0.50 D. LV^If; fi with + 0.50 D. cyl., ax. 90°. Orthophoria ; exophoria in accommodation, 1°.

Ophthalmoscopic appearances normal. February 1.—The above cylindrical glasses, which gave him the best vision while his accommodation was suspended by homatropine, being now placed before the patient's eyes, in trial frames, were found to be comfortable while they sharpened his vision a little. They were, therefore, prescribed for constant use. February 16.—Mr. G-. has been wearing the glasses constantly since ordered, and expresses himself as much relieved by them. Dr. Corning, who kept the patient under treatment for some time, assures me that the glasses aided him greatly in the restoration of Mr. G.'s health, and in the permanent relief of his headache. Thus we find that the correction of ocular errors, while not of itself always sufficient to relieve head symptoms, is often an invaluable adjunct to medical treatment. Case IV.—Nov. 15,1887.—G. E. K., set. 33, banker, was referred to me by Dr. E. C. Seguin, who wrote: He presents the occipito-cervical symptoms charac- teristic of eye-strain.
