The subject of Dr. Horace T. Brown's Chemical Section address was The Assimilation of Carbon by the Higher Plants. Sir William H. White, president of the Section of Mechanical Science, spoke on Steam Navigation at High Speeds. President Adam Sedgwick addressed the Zoölogical Section on Variation and some Phenomena connected with Reproduction and Sex; Sir John Murray, the Geographical Section on The Ocean Floor; and Mr. J. N. Langley, the Physiological Section on the general relations of the motor nerves to the several tissues of the body, especially of those which run to tissues over which we have little or no control. The president of the Anthropological Section, Mr. C. H. Read, of the British Museum, spoke of the preservation and proper exploration of the prehistoric antiquities of the country, and offered a plan for increasing the amount of work done in anthropological investigation by the use of Government aid. A peculiar distinction attaches to this meeting through its reception and entertainment of the French Association, and the subsequent return of the courtesy by the latter body at Boulogne. About three hundred of the French Associationists, among whom were many ladies, came over, on the Saturday of the meeting, under the lead of their president, M. Brouardel, and accompanied by a number of men of science from Belgium. They were met at the pier by the officers of the British Association, and were escorted to the place of meeting and to the sectional meetings toward which their several tastes directed them. The geological address of Sir Archibald Geikie on Geological Time had been appointed for this day out of courtesy to the French geologists, and in order that they might have an opportunity of hearing one of the great lights of British science. Among the listeners who sat upon the platform were M. Gosselet, president of the French Geological Society; M. Kemna, president of the Belgian Geological Society; and M. Rénard, of Ghent. Public evening lectures were delivered on the Centenary of the Electric Current, by Prof. J. A. Fleming, and (in French) on Nervous Vibration, by Prof. Charles Richet. Sir William Turner was appointed president for the Bradford meeting of the association (1900). The visit of the French Association was returned on September 22d, when the president, officers, and about three hundred members went to Boulogne. They were welcomed by the mayor of the city, the prefect of the department, and a representative of the French Government; were feasted by the municipality of Boulogne; were entertained by the members of the French Association; and special commemorative medals were presented by the French Association to the two presidents. The British visitors also witnessed the inauguration of a tablet in memory of Dr. Duchesne, and of a plaque commemorative of Thomas Campbell, the poet, who died in Boulogne.
