EDITORIAL NOTES. 



The annual meeting of the German Association for the Advancement 

 of Science {Gesellschaft deutscher Katurforscher unci Aerzte) was held 

 in Halle, September 21-25, 1891. This Association was organized in 

 1822. It includes thirty-two sections, of which ten may be reckoned as 

 representing general mathematical and physical science, and twelve as 

 more especially relating to medicine and surgery. The Halle meeting 

 was the sixty-fourth in the history of the Association. The number of 

 members and associates {Theilnehmer) in attendance was rej)orted as 

 about 1,300, and included many of the leading scientific men of Ger- 

 many and a number from other countries. Addresses of general interest 

 were delivered at the general sessions, and many papers representing 

 the latest and best research in special lines were presented and 

 discussed at the meetings of the several sections. The next year's 

 meeting is to occur in Nuremberg. 



The sessions of the Section for Agricultural Chemistry and Agricul- 

 tural Eesearch {Ahthellung fiir AgriJculturchemle und landwirt.schaft- 

 liches Versuchswesen) were of marked interest. Among the well-known 

 German investigators present were von Wolflf, Nobbe, G.Kuhn, Stoh- 

 mann, Wagner, Stutzer, Maercker, Hellriegel, H. Schultze, Konig, Die- 

 trich, Orth, Emmerling, and Bretschneider. Among the foreign guests 

 were Dr. Gilbert of Rothamsted, England; Professor Mayer of Wage- 

 ningen, Holland; Professor Kellner of Tokio, Japan; and Professor 

 Atwater of the United States, 



The intervals between the sessions gave opportunity to visit the 

 experiment station of the Central Agricultural Society of the Piovince 

 of Saxony, Prussia, and the Agricultural Institute of the University, 

 with its laboratory of vegetable physiology and experiment station 

 {Versuehsanstalt). The station of the provincial society, commonly 

 known as the Halle Experiment Station, has no official connection with 

 the institute or its station, although Professor Maercker, the director 

 of the Halle Station, is professor in the institute. The exj)erimental 

 work of the institute is largely in the study of diseases of plants.
