§ SIR H. ROSCOE (Manchester, S.)I beg to ask the President of the Board of Trade whether the Committee on Colour Vision, appointed by the Royal Society at his suggestion, is about to issue a Report before the end of the present Session?
§ *SIR M. HICKS BEACHI am informed that the Committee have prepared a Draft Report, but the subject has been found so difficult that the Committee consider it still necessary to make further inquiries and practical experiments, and it is not probable that the Report will be presented until next year.
