THE fiftieth meeting of the German Association of Naturalists and Physicians began on September 17 by a large assembly of visitors in the old Town Hall at Munich. The meeting this year assumed quite a national character. Although in the programme its scientific character was principally considered, and pleasure trips, banquets, &c., had been reduced to the most modest proportions in comparison with former years, yet the aspect of the city of Munich, and of all the edifices that were in any way connected with the meeting, was a festive one. Some 2,000 visitors had arrived, and the Town Hall on the night of the 17th was crowded to suffocation. The authorities of the city gave a grand Keller-Fest in honour of the visitors on the 20th, which was attended by over 5,000 guests.
