THE thirtieth meeting of the American Association for the Advancement of Science commenced at Cincinnati on August 16. Always a hot place in summer, the temperature at Cincinnati during the past two months has been at intervals unusually high, running above 100° for several days together. This and the fear of its recurrence no doubt induced many to stay away who would otherwise have been present. However, a goodly number —over 400—of new members were enrolled, and many papers of interest were read. Some of the visitors from the Eastern States were amazed to find that Cincinnati was not a little backwoods town, but a city deserving in many ways the title she claims, “The Queen City of the West.” The ignorance of many of the inhabitants of the Eastern States in regard to the West is only equalled by the ignorance of Europeans in regard to America generally.
