WHEN the Physical Society of London was founded in March 1874, a paper “On the New Contact-Theory of the Galvanic Cell” was read by J. A. Fleming (now Sir Ambrose Fleming). Since then, sixty-four years have elapsed, yet this veteran physicist and engineer is still taking part in scientific work. It is therefore with particular interest that we see the announcement in the Society's programme that he is to give an address on January 13 next, on “Physics and Physicists of the Eighteen-Seventies”. Other noteworthy meetings included in the programme are: the twenty-third Guthrie Lecture by Prof. A. V. Hill, on the transformation of energy and the mechanical work of muscles (Nov. 11); a discussion on electro-acoustics, to be opened by Dr. C. V. Drysdale (Dec. 9); discourse by Dr. J. D. Cockcroft on the cyclotron and its applications (Jan. 3); discourse by C. S. Wright on geophysical research in Polar regions (Jan. 4); joint meeting with the Royal Astronomical Society for a discussion on the expanding universe, to be opened by Prof. G. F. J. Temple and Dr. G. C. McVittie (Jan. 27); the Thomas Young oration by Brigadier?.?. MacLeod on some recent developments in British surveying instruments (March 24); and joint meeting with the Chemical and Royal Meteorological Societies, for a discussion on chemical and physical investigations of the upper atmosphere, to be opened by Prof. F. A. Paneth (May 4). The president of the Society this year is Prof. Allan Ferguson; and it is evident from the programme that he desires the meetings to be of wide interest and not confined to the communication of technical papers which are better presented by title for publication in the Proceedings than read.
