The original scheme of committee work divided observations of electric lamps among four different sections, known respectively as the sections on "Arc Lamps," "Carbons for Arc Lamps," "Incandescent โข I" Lamps." and "Photometric Measurements." As the membership of all these sections was the same, it was soon found that this subdivision entailed unnecessary wor k and needless discussion, and the four sections were theretbre consolidated into a group, designated by the Executive Comnfittee as "Group B."* Tire work of this group covered the whole subject of measurements on electric lamps.
