positive programme for change: the Thirteenth Science Exhibition. on 21st and 22nd March. The theme for the exhibition was topical and exciting: Science and the Environment. This idea was particularly well executed by the physics department. The production of power from wind (most lectures) and solar power (my lectures) to a study of transformers and perpetual motion (Mr Hamilton) were among the exhibits. In the Rutherford Laboratory exhibits were designed to emphasize the applied aspects of science. The demonstration of the heat retention of double glazed windows and of cavity wall insulation was most impressive to a shivering Calif ornian. Mr P. L. Harris, the noted alchemist, informed this reporter that every aspect of chemistry is in some way related to the environment. The various smells which emanated from the Ramsay Laboratory made one realize that the environment can be both harsh and odiferous. The exhibits were reasonably easy to understand and were explained with sophistication. Professor M. H. Williamson, whose short address opened the exhibition, emphasized the range of sciences concerned with ecology. This aspect of his talk was proved correct when one walked around the St Peter's campus and observed the wide range of exhibits. Under the broad umbrella of biology alone much was to be noted. Boys showed their skill in dissection—always a crowd pleaser. Two less theatrical but important displays were on soil fertility and water pollution. The most impressive aspect of the exhibition was the energy and enthusiasm of the boys as they explained their displays. Boys noted for a certain sullen reticence found a new ability. Their explanations were articulate and accurate. This writer was also pleased that over 300 boys took part in the days' events. It would have been easy to have a few star students demonstrate projects, but the science staff involved most of the boys in the planning and construction of the 102 displays. The exhibition also drew on the skills of several non-scientific areas. The geography, maths and English departments were well represented.. Perhaps that is why I ended the day feeling optimistic. The problems of science and the environment will be solved if men of good will leam to shed their narrow specialities and co-operate in their attempts to solve problems. R. D. WILKOFF.
THEOLOGICAL SOCIETY There have been four meetings this year. The first was well attended, but the following three were supported by a small but enthusiastic corps of members. The first meeting was held in the Studio (the weather being too cold for a meeting in the Stephenson Room), on Friday, 11 th October. Before the meeting it had been decided that in the past people had enjoyed hearing other people stating their religious views, and it was suggested that the meeting should take this form. So the meeting consisted of short talks by three members of the staff on "What I believe and why". 28
