De. p. Blaserna, professor of physics at 

 Eome, celebrated on April 30 the fiftieth anni- 

 versary of his academic activity. 



Dr. Harry Fielding Reid, professor of phys- 

 ical geology at the Johns Hopkins University,

 fornia as a member of a commission to in- 

 vestigate this summer the causes of the recent 

 earthquake. 



Dr. Harry T. Marshall, instructor in pedi- 

 atrics, Johns Hopkins University, has ac- 

 cepted a position as pathologist in the Bureau 

 of Science at Manila. 



Professor Wm. H. Hobbs has resigned the 

 chair of mineralogy and petrology at the Uni- 

 versity of Wisconsin, in order to devote his 

 energies wholly to structural and dynamical 

 geology and physiography, which subjects have 

 largely constituted his field of research. Pro- 

 fessor Hobbs expects to spend another year in 

 Italy engaged in studies growing out of the 

 late Calabrian earthquake. 



Dk. Henry E. Crampton, professor of zool- 

 ogy in Barnard College, Columbia University, 

 has returned from a scientific expedition of 

 three months to the island of Tahiti, the So- 

 ciety group. He went for the American Mu- 

 seum of Natural History to study various 

 species of mollusca which have undergone indi- 

 vidual evolution in the isolated valleys of this 

 island. 



Professor Eobert Koch, who returned to 

 equatorial Africa in March in order to con- 

 tinue the study of tropical diseases, has writ- 

 ten to the Berlin Medical Society, saying that 

 he has become so interested in his further re- 

 searches, especially in connection with the 

 ' sleeping sickness,' that he will not return to 

 Germany for two years. Dr. Koch, therefore, 

 resigns the presidency of the society. 



Professor H. H. Horne has been granted a 

 Sabbatical year of leave by Dartmouth Col-

Professor James F. Kemp, of Columbia 

 University, has been delivering during April

 Johns Hopkins University a course of lectures 

 on ' The Origin of Ore Deposits.' The sub- 

 jects of his lectures are : (1) The general prob- 

 lem. (2) Underground waters. (3) Water- 

 ways and places of precipitation. (4) Veins 

 (structural features, methods of study, etc.). 

 (5) Contact deposits. (6) Magmatic segrega- 

 tions. (7) Secondary enrichment. (8) Sedi- 

 mentary deposits. (9) Placers. (10) Geology 

 in the law. 



Professor Friedrich Mijller, of Munich,

 chemistry at the University and Bellevue Hos- 

 pital Medical College in the spring of 1907. 

 The lectures will be given in English.
