On the 27th of August, the British Association commenced its fifty-fourth annual meeting—not this year, however, on British soil, but at Montreal in Canada. Some hundreds of members travelled from this country to be present at the meeting. Both on the part of the city and of the Dominion, the reception of the Association has been everything that could be desired by its members. Montreal itself raised forty thousand dollars towards defraying the expenses of the visit, and three hundred of the members were, besides, received as guests into private houses. The new President, Lord Rayleigh, Professor of Experimental Physics in the University of Cambridge, delivered the opening address, in which he sketched the progress that had been made in certain important branches of science. The final meeting of the Association was held on the afternoon of September 3, and was largely attended, about two thousand persons being present. Lord Rayleigh in addressing the assembly, said that no meeting had been held in which the Association had been provided with such spacious rooms. Resolutions in favour of the erection of a free public library in Montreal, as a memorial of the visit, were then passed, and a large amount of money was immediately promised in aid of this object, among the donations being one of ten thousand pounds. The total money grants in favour of scientific investigations made at the Montreal meeting were fifteen hundred and fifty pounds. The tickets issued for members of the Association for this session numbered seventeen hundred and thirty, and the money received amounted to eighteen hundred pounds.
