The corneal surfacewas not appreciably elevated by the projecting tongue, and theremaining portions of the membrane were perfectly clear. I must regard these opacities and the adhesion of the eyelidto the globe as of inflammatory origin, yet in a most carefulstudy of the corneas with a strong loup no obliterated nor patul-ous vessels could be found, and as the irises were normal in theirstructure and in their functions, it is all the greater evidence thatthey were not caused by disturbance in the evolution of the em-bryologic layers. The patient would not allow me to remove any. ?^ Dr. Burton Chances case of unusual corneal condition of pre-natal origin Tyson: Cyanosis Retinae. 531 portion of the abnormal tissues: I can only conjecture as totheir histology. The lenses were dark and densely opaque and about the pefi-phery of each there was a singular festooning of the superficialelements : there were neither stars nor radii. In all fields therewas good light-projection. The left crystalline was extracted by the combined method,without accident, after which the patient was able to recognizethe window bars. The incision was made straight through thescleral tongue. The capsule was dense and very tough. Thecataract was of a deep brown color; it was large and had butlittle cortical. The healing progressed rapidly. In two weeks the lady cameto my ofiice; the eye was then quiet and a hasty trial of thevision gave 5/15. One week later a thin web of capsule stretch-ing across the nasal half of the coloboma was discinded. Onthe removal of the Hays Knife a
