Under a grant from the Smithsonian In- 

 stitution, just approved by Secretary Walcott, 

 Mr. Bailey Willis, of the United States Geo- 

 logical Survey, will be sent to Europe this 

 summer to study the types of geological struc- 

 ture involved in the Alps. Mr. Willis will 

 leave on the first of August for a two months' 

 trip, during which he will make observations 

 at the most important spots in Italy and 

 Switzerland, and confer with a number of 

 geological experts. On his return he will 

 formulate his investigations into a report 

 which will be published by the Smithsonian 

 Institution. 



Dr. David Eugene Smith, professor of 

 mathematics of Teachers College, Columbia 

 University, has next year his sabbatical year 

 of absence, which he will spend mainly in 

 Asia, making collections of manuscripts and 

 instrximents illustrating the history of mathe- 

 matics. 



Dr. C. R. Weiland, of the Peabody Museum, 

 Yale University, has left for a stay of five 

 months in Europe where he will visit the plant 

 collections of northern and southern Europe 

 for a special study of cycads. The results of 

 his investigations will be published in his 

 second volume on cycads. 



Professor Liveing, for forty-six years pro- 

 fessor of chemistry at the University of 

 Cambridge, expects to rehire next year. 



Dr. Werner Janeusch has been appointed 

 curator of the Geological and Paleontological 

 Institute of the University of Berlin, and Dr. 

 Otto Schneider has been given charge of the 

 collections of the Geological Institute. 



Professor Frederick C. Shattuok, of Har- 

 vard University, will give the annual address 

 before the Medical School of Yale University 

 on June 24, his subject being the ' Art and 

 Science of Medicine.' 



From May 6 to May 10 Professor E. H. 

 Chittenden, director of the Sheffield Scientific 

 School of Yale University, lectured at the 

 University of Illinois on the general subject 

 of ' Nutrition.' In the course of six lectures 



Professor Chittenden outlined our present 

 knowledge of the physiology of nutrition, and 

 gave a historical and critical discussion of 

 dietary habits and experiments bearing on 

 true food requirements. The general trend 

 of the lectures was toward the conclusion that 

 the most advantageous diet for man is one 

 that includes a minimum of proteid material, 

 i. e., the amount actually needed to meet the 

 physiological requirements of the body. A 

 reception in honor of Professor Chittenden 

 was held at the conclusion of the opening 

 lecture of the series. 



Mr. Charles E. Scott, consulting engineer 

 of the Westinghouse Manufacturing Com- 

 pany, will give the commencement address on 

 June 13 at the Worcester Polytechnic Insti- 

 tute, his subject being ' Some Aspects of Elec- 

 trical Development.' The annual commence- 

 ment lecture will be given on June 11 by 

 Mr. A. S. Eitchey, a professor of electrical 

 railway engineering, on ' The Electric Eail- 

 way.' 



The fifteenth ' James Forrest ' lecture be- 

 fore the Institution of Civil Engineers, Lon- 

 don, will be delivered by Dr. Francis Elgar, 

 F.E.S., on June 18, his subject being ' Un- 

 solved Problems in the Design and Propulsion 

 of Ships.' The fourth engineering conference 

 will be held on June 19, 20 and 21, and the 

 annual conversazione will be held on the eve- 

 ning of June 20, at the Eoyal Albert Hall. 



Beginning on May 23 Sir James Dewar is 

 giving three lectures before the Eoyal Insti- 

 tution on Chemical Progress-work of Berthe- 

 lot, Mendeleef and Moissan. 



The fund for a memorial to the late Eobert 

 Henry Thurston, director of Sibley College, 

 is now complete. This fund, started by the 

 four classes in college at the time of Dr. 

 Thurston's death, but since added to by other 

 Sibley students, amounts to about $1,600. 

 The memorial will be a bronze bust of Dr. 

 Thurston by Herman Atkins MacNeil, of New 

 York, formerly instructor in Sibley College. 

 The bust will be placed in the central Sibley 

 building. 



The two-hundredth anniversary of the birth 

 of LinnsBus was celebrated at Augustana Col-
