Mathematical and Physical Society

For its thirteenth session, the Mathematical and Physical Society has done remarkably well—no major catastrophe having occurred during the year.

The average attendance at meetings for the year was 23 and at Supper, which is invariably free, 23.03. So far the high attendances at Supper have not been satisfactorily explained.

The papers presented during the year were as follows:—

The Photography of Sound Waves: Mr. N. R. Palmer.

Sundials: Professor D. M. Y. Sommerville.

Power Amplifiers: Mr. C. G. Liddell.

Sir Douglas Mamson's Antarctic Expedition: Mr. R. G. Simmers.

An introduction to Relativity: Mr. F. F. Miles, M.A.

Atmospheric Electricity: Mr. H. I. M. Abraham.

The Construction and Theory of Alignment Charts: Mr. F. Smart.

Solar Physics: Mr. I. L. Thomsen.

The thanks of the Society are due to Mrs. Florance, Mrs. Sommerville, and Mrs. Palmer who kindly provided supper on many occasions during the year.
