Professor Hugo de Vries will visit this 

 country again in September and October next. 

 His itinerary, so far as can be arranged in 

 advance, is to reach New York about Sep- 

 tember 12, where he is to give a lecture at the 

 Botanical Garden on September 14. Prom 

 there he goes to the University of Pennsyl- 

 vania to see the work which Professor Davis 

 is doing with (Enotheras, and will then spend 

 a short time in Washington. His next ob- 

 jective point will be Dixie Landing, Ala., 

 where he goes with Professor Tracy to visit 

 the type locality of (Enothera grandiflora to 

 study its possible mutants in its original hab- 

 itat. He will then go to Biloxi, Miss., where 

 he will make his headquarters while he visits 

 the " mud lumps " near the mouth of the 

 Mississippi River, and a number of the islands 

 near Biloxi. After that he and Professor 

 Tracy will go to San Antonio, Brownsville 

 and other points in southern Texas, where 

 Professor de Vries goes to study the relations 



of the flora to the geological and geographical 

 conditions. On October 14, Professor de Vries 

 is to deliver the dedicatory address of the Rice 

 Institute, at Houston, Texas. 



Professor Rollin D. Salisbury, head of 

 the department of geography and dean of the 

 Ogden Graduate School of Science in the 

 University of Chicago, has been granted leave 

 of absence during the autumn quarter for the 

 purpose of scientific investigations in South 

 America. Professor Salisbury, in company 

 with Mr. Bailey Willis, of the U. S. Geolog- 

 ical Survey, sailed from New York on Au- 

 gust 10 for Panama, whence they cross the 

 isthmus and go down the west coast of South 

 America as far as Valparaiso, Chile. A few 

 days will be spent on the west side of the 

 Andes, with a possible trip southward as far 

 as the railroad will carry them in Chile, and 

 the party will then cross the range by the 

 Trans-Andean Railway, going into northern 

 Argentina and then down to Buenos Aires. 

 About October 1 Professor Salisbury intends 

 to camp in Patagonia at Lake Nahuel 

 Haupi in the eastern Andes in latitude 41°. 

 On his return he expects to stop at Rio de 

 Janeiro and go back into the interior from 

 that point to the great iron deposits of 

 Brazil. 



The American Museum of Natural His- 

 tory has received a telegram from V. Stefan- 

 son, who has been conducting an ethnological 

 and zoological expedition in the Coppermine 

 River region and adjacent islands in the 

 Arctic Ocean. This telegram is dated Aug- 

 ust 18, and was sent by way of the revenue 

 cutter Bear to Nome and thence to Seattle. 

 It says that Mr. Stefansson arrived at Point 

 Barrow, Alaska, on June 13. He reports that 

 he devoted the winter to studies of the lin- 

 guistics of the Eskimo and the summer to the 

 excavation of ancient village sites. He has 

 some 50,000 areheological specimens. On 

 this expedition he was accompanied by Dr. R. 

 M. Anderson. Mr. Stefanson reports that 

 Anderson and the eastern collections, that is 

 collections from the Coppermine River re-
