THE executive committee of the Association of Scientific Workers has sent a message of greeting to French men of science who have taken part in the Resistance Movement in France. "It looks forward to close collaboration between the scientific workers of both our countries for the progress of our common aims: the development of science and its use to advance the living and cultural standards of all peoples". The Association des Travailleurs Scientifiques, formed from the Resistance Movement a few days after the liberation of France, has acknowledged this greeting conveyed through Prof. Joliot-Curie. "In its refusal to accept the defeat of France as final and to submit to the subsequent German domination, the Resistance movement has, since 1940, been animated by that same spirit which inspired the entire British nation when it decided to continue the struggle. This community of ideas concerning the conduct of the war must continue in the maintenance of peace. The great contribution made by science to the national defence can be continued in the economic and social spheres of the peace-time world organization of to-morrow."
