January meeting A.I.E.E.

The two hundred and thirty-third meeting of the American Institute of Electrical Engineers will be held in the Auditorium of the Engineers´ Building, 33 West Thirty-ninth street, New York, on Friday, January 8, 1909, at 8 o´clock p.m. Mr. Elihu Thomson, past-president of the Institute and electrician of the General Electric Company of West Lynn, Mass., will present a paper entitled, “Conditions Affecting Stability in Electric Lighting Circuits.” The paper is printed in this issue of the PROCEEDINGS, pages 1–22, and paper contains an interesting account of the various methods tried during the last 30 years in the effort to obtains tability of current or potential, or both, in electric lighting circuits, circuits whose load is inherently unstable owing to the peculiarity of the arc-resistance falling with increase of current.
