Mathematical and Physical Society.

The Society is more than ever indebted to Mrs. Florance and Mrs Sommerville for providing those delectable suppers which are an extremely popular feature of the Society's evenings.

Two innovations have been introduced this year. First, a series of visits has been arranged. The Society's sincere thanks are due to the Union Steamship Company for permission to visit the T.E.V. "Rangatira," Messrs Filmcraft Ltd., for their courtesy in demonstrating the recording and processing of films, the Railway Department for permission for the lecture on "Signalling," and a visit to the Woburn Shops and to the "Evening Post," the Dominion Analyst and the Dominion Astronomer.

The demonstrations arranged with the lectures by Mr. Gentry, of the Post and Telegraph Laboratory, and Mr. Graydon, of Messrs Watson and Sons, were of particular interest, the first being the actual setting up and working of the most modern form of telegraph apparatus, and the second a surgical diathermy plant which to the delight of all present performed very interestingly on a piece of steak and an egg. The Society is grateful to the Post and Telegraph Department and Messrs Watson and Sons for permitting these lectures and thus enabling mathematics and physics students to gain a truer perspective of the realms of their subjects.

The second feaure which has been introduced this year is the devotion of one evening, August 9th, to an account of the research work being carried out this year in the Physics Department. The meeting will be held in the advanced laboratory, and the actual apparatus will be demonstrated by the students concerned.
