The Dover Meeting of the British Association.--While the attendance on the meeting of the British Association at Dover was not large--the whole number of members being 1,403, of whom 127 were ladies--the occasion was in other respects eventful and one of marked interest. The papers read were, as a rule, of excellent quality, and the interchange of visits with the French Association was a novel feature that might bear many repetitions. The president, Sir Michael Foster, presented, in his inaugural address, a picture of the state of science one hundred years ago, illustrating it by portraying the conditions to which a body like the association meeting then at Dover would have found itself subject, and suggesting the topics it would have discussed. The period referred to was, however, that of the beginning of the present progress, and, after remarking on what had been accomplished in the interval, the speaker drew a very hopeful foreview for the future. Besides the intellectual triumphs of science, its strengthening discipline, its relation to politics, and the "international brotherhood of science" were brought under notice in the address. In his address as president of the Physical Section, Prof. J. H. Poynting showed how physicists are tending toward a general agreement as to the nature of the laws in which they embody their discoveries, of the explanations they give, and of the hypotheses they make, and, having considered what the form and terms of this agreement should be, passed to a discussion of the limitations of physical science.
