THE SCIENCE SOCIETY At the first of the term's five meetings, the Rise provided lectures on three subjects. They were (i) J. R. Moore and M. W. Bolton on "Colour and Fluorescence". This lecture consisted mainly of demonstrations by means of the projector with coloured filters and the Ultra Violet lamp. (ii) W. R. Ibberson on "Steel". The speaker outlined the story of the knife through the stages of hardening, tempering and glazing. Specimens of knives in various stages of manufacture were examined by the Society. (iii) P. D. F. James and A. N. Wyatt-Gunning on "The Human Body". The speakers dealt in turn with each of the five senses, demonstrating their more amusing characteristics.

At the second meeting lectures were given by the Grove. The speakers were (i) A. E. Wick on "Explosives". A talk mainly on gunpowder and the explosives derived from coal. His lecture included many demonstrations. (ii) D. A. Stabler on "Chocolate". He outlined the processes through which the cocoa beans passed until they were finally in the state with which we are familiar. (iii) M. J. F. Everitt on "Television". Everitt explained how the picture on the screen was made up and how it was transmitted. He concluded by showing a film illustrating the points he had made.
