A RRANGEMENTS for a scientific delegation from Great Britain to India this winter are nearing completion. The Indian Science Congress Association, which holds annual meetings in different parts of India of individual scientific workers and others, and functions much on the lines of the British Association for the Advancement of Science, is approaching the celebration of its jubilee (twenty-fifth) session at the meeting to be held in Calcutta in January next. The Association invited the co-operation of the British Association in forming a representative visiting delegation from this country and others, and the General Committee of the British Association eagerly accepted the invitation, which was, in effect, to make a new use of the mechanism of the Association, and one which is felt to suggest far-reaching implications. It is common knowledge that the British Association has sometimes held its own annual meetings overseas, at the invitation of Dominion Governments and institutions. But it has never before been asked to co-operate in organizing a scientific delegation apart from its own annual meetings—and if this can be done for India, why not for other parts of the Empire in which conditions would not permit of a meeting of the Association on ordinary lines? But this is to anticipate: the present notice is concerned with the Indian meeting.
