Arthur H. Blanchard, consulting highway 

 engineer, has been appointed chief of the Bu- 

 reau of Public "Works, Department of Citizen- 

 ship, imder the Army Overseas Educational 

 Commission. 



Major George F. Setor, Engineers, TJ. S. A., 

 has been honorably discharged from the 

 United States Army after a service of fifteen 

 months and will make his headquarters in 

 New York City for consulting engineer prac- 

 tise. Major Sever during his service made 

 extensive and detailed investigations of the 

 electric power conditions in New England as 

 well as on the Pacific coast from Seattle to 

 Los Angeles. His investigations covered 

 analyses of the production of power by coal, 

 oil and water, and the comparisons of these 

 different methods. 



Second Lieutenant Asa C. Chandler, Sani- 

 tary Corps, formerly assistant professor of 

 zoology at Oregon Agricultural College, has 

 undertaken parasitological work at the Central 

 Medical Department Laboratory of the A. E. F. 

 at Dijon, France. 



Professor J. M. Aldrich, formerly pro- 

 fessor of zoology in the University of Idaho, 

 has been appointed associate curator of the 

 Division of Lisects in the National Museum, 

 but more recently has been working with the 

 Bureau of Entomology. 



Dr. Hermann von Ihering, formerly director 

 of the Musemn of the State of Sao Paulo, 

 Brazil, has been appointed director of the 

 State Museum of Sta. Catharina, Brazil, to be 

 organized by him at Flerianopolis (Estado de

At its meeting held May 14, 1919, the Eum- 

 ford Committee of the American Academy of 

 Arts and Sciences voted the following appro- 

 priations: To Professor P. W. Bridgman, of 

 Harvard University, in aid of his research on 

 the effect of temperature and pressure on the 

 physical properties of materials, particularly 

 their thermal conductivity (additional to 

 previous appropriation), $400; to Professor 

 Horace L. Howes, of the New Hampshire Col- 

 lege, in aid of his research on the experimental 

 study of the effect of temperature on the 



luminescence and selective radiation of the 

 rare earths, $500. 



A NEW acoustical laboratory has just been 

 completed at Riverbank, Geneva, Illinoia. This 

 laboratory was built for the late Professor 

 Wallace C. Sabine, of Harvard University, by 

 his friend, Colonel George Fabyan. In this 

 laboratory Professor Sabine proposed to carry 

 on the study of a number of problems in archi- 

 tectural acoustics requiring special building 

 construction and entire freedom from extrane- 

 ous noises. The building was constructed with 

 the most careful attention to details, according 

 to Professor Sabine's plans, and has many in- 

 teresting structural features. It was just ready 

 for occupancy at the time of his death. Col- 

 onel Fabyan, the founder of the laboratory, 

 proposes to carry out, as far as jwssible, the 

 original purpose for which the building and its 

 equipment were intended. Dr. Paul E. Sabine 

 has resigned his position as assistant professor 

 of physics in the Case School of Applied Sci- 

 ence to take chaise of the research program 

 which had been laid out. 



An entomological expedition to South Amer- 

 ica is planned by Professor J. Chester Bradley, 

 '06, of the college of agriculture of Cornell 

 University. Leaving Ithaca next September, 

 Professor Bradley will visit Brazil, Argentina 

 and Chile; in the following spring he wiU be 

 joined in Peru by Professors Cyrus R. Crosby 

 and Dr. W. T. M. Forbes, of the agricultural 

 college, and the party will work on the Ama- 

 zon River as far as Peral near the headwaters. 

 The expedition is conducted under the auspices 

 of the university for the two-fold purpose of 

 securing entomological specimens and of form- 

 ing closer relations with South American in- 

 stitutions of learning. 



Dr. S. M. Zeller, who has been special in- 

 vestigator in timber pathology for the South- 

 ern Pine Association, of New Orleans, La., 

 with laboratory at the Missouri Botanical Gar- 

 den, St. Louis, has been appointed investigator 

 in fruit diseases at the Oregon Agricultural 

 College, Corvallis, Oregon. 



After being at work for one year, the tech- 

 nical personnel of the Bacteriological Insti-
