A STUDY OF THE REFRACTION OF SEVENTEEN HUNDRED EYES.

The question of refraction is one that plays no unimportant part in the daily work of many oculists in our large cities, and of most oculists in our medium and smaller cities. With many it forms the great bulk of their work. I present for your consideration to-day, in tabular form, a study of the refraction of 1,700 eyes, representing 869 patients taken from the last 1,000 consecutive eye cases coming under the care of the writer in his private practice. Of the 131 cases not incorporated in this study, some were infants with various inflammatory troubles and some operative cases, five only being presbyopes with emmetropic eyes. Thus you will see that about 87 per cent. of all my eye cases required correction of ametropia. Dr. Geo. M. Gould in a paper on these very lines, read before this Section in 1891 said that 93 per cent. of his
