THE Joint Council of Professional Scientists was established for the period of the national emergency, to voice the collective opinion of qualified men of science. It was originally a joint committee of representatives of the Royal Institute of Chemistry and of the Institute of Physics, which was set up for the purpose of fostering co-ordinated action in matters of common interest, and was developed by the co-option of a botanist, a geologist, a mathematician and a zoologist, there being no corresponding professional bodies to represent those branches of science. One of the representatives of the Royal Institute of Chemistry is a metallurgist of similar standing. The Council has now been working for two years. Among matters which have received, or are receiving, its attention are the proposal to urge the Government to establish a central scientific and technical board; the Ministry of Labour's announcement regarding the minimum number of hours to be worked in laboratories and factories; the influence, on professional standards, of war-time university regulations governing the award of degrees; the conditions of service of professional men of science in the Colonial service; and the national policy regarding research and development work.
