Moscow Eye Hospital.

I at the appropriate distance between the ophthalmoscope and the eye under inspection if greater resolution is desired. The lens must not fluoresce, and all examinations are made in a darkened room. There appear to be a number of interesting possibilities for the ultraviolet ophthalmoscope in medical and biological science, not only for the study of the internal eye structures, but also for the examination of such exposed regions as the brightly fluorescent sclera. As is well known, cataract tissue fluoresces differently than its normal surroundii)g tissue: hence, with this instrument greater assurance might be had of complete removal of all pathological tissue from the cornea; lesions of the cornea and sclera are revealed by their green fluorescence after uranine solution has been dropped into the eye; neoplasms and other disease tissue present marked differences under high intensity ultraviolet light, as frequently do the different kinds of normal tissue.

ON Gorky Street, Moscow's main thoroughfare, stands the Moscow Eye Hospital, one of the largest and oldest ophthalmological institutions in the country. Founded 120 years ago its scope was at first quite limited. There were only two staff doctors, only 30 people a day passed through the out-patients' department and the hospital was equipped with only 20 beds. Now the out-patients' department is visited daily by 500 people and the number of beds has increased to 250. The growth of the hospital dates from the post-revolutionary years when the whole of the medical service was reorganized. Thus, for example, in 1917 only 200 clinical analyses per month
