To the Editor:
—In the report of the Committee on Hereditary Blindness presented to the Section on Ophthalmology at the recent session of the Association (The Journal, July 18, p. 192), the following statement appears: "Various estimates thus far made by students of this question have placed the number of those blind in the United States from hereditary causes as from about 75,000 to 100,000." Such a number would be truly appalling if the facts substantiated this statement, but I fear that the committee has been greatly misled in its statistics. The 1920 United States Census places the total number of blind in the United States at 57,444 persons. As this number represents practically no increase over the similar item given in the 1910 census, we may conclude that the number of blind from all causes in the United States at the present time is not far different from that
