THE American Association for the Advancement of Science will hold its thirty-first annual meeting in Montreal during the week beginning Wednesday, August 23, 1882, under the presidency of J. W. Dawson, LL.D., F.R.S. A large attendance is expected from the United States and Canada, and it is hoped that there will be a good number of visitors from the British Islands and Continental Europe. The new Redpath Museum of the University, then to be opened, will contain remarkable collections, in part gathered for the occasion, illustrating American Geology and Archæology. The Allan and Dominion lines of steamers have placed at the disposal of the Local Committee a considerable number of passages from Liverpool to Quebec and back, at much reduced rates, and arrangements will be made for entertaining private visitors. Circulars, giving full particulars, will soon be issued, but meanwhile it is requested that any persons proposing to avail themselves of the occasion will communicate as soon as possible with Dr. T. Sterry Hunt, Montreal, Canada.
