 year by Columbia University, on the recom- 

 mendation of the National Academy of Sci-

 years nest preceding, has made such discovery 

 in physical or astronomical science, or such 

 novel application of science to purposes bene- 

 ficial to the human race, as may be deemed by 

 the National Academy of Sciences most 

 worthy of the honor," will be given this year to 

 William H. Bragg, D.Sc, F.E.S., Cavendish 

 professor of physics in the University of Leeds, 

 and to his son, W. L. Bragg, of the University 

 of Cambridge, for their researches in molecular 

 physics and in the particular field of radio- 

 activity. The previous awards of the Barnard 

 medal have been made as follows :

 recommendation of The Franklin Institute, 

 has awarded the John Scott Legacy Medal and 

 Premium to Herbert Alfred Humphrey, of 

 London, England, and to Cav. Ing. Alberto 

 Cerasoli, of Rome, Italy, for the Humphrey 

 Pump, a device for raising water by the direct 

 application of the explosive energy of a mix- 

 ture of combustible gas and air. In the 

 pump, the momentum of a moving column of 

 water is utilized to draw in and compress in a 

 suitable chamber a charge of the gas mixture 

 whose explosion raises the water. 



The Edward Longstreth Medal of Merit of 

 the Franklin Institute has been awarded to 

 the late Mr. George A. Wheeler for his esca-

 and a number of patents were subsequently is- 

 sued to him for improvements and develop- 

 ments. 



At the annual meeting of the Boston So- 

 ciety of Natural History, held on May 5, the 

 two annual Walker Prizes in Natural History 

 were awarded. The first, of sixty dollars, was 

 given to Miss Emmeline Moore, of the depart- 

 ment of biology, Vassar College, and the sec- 

 ond, of forty dollars, to Miss Edith B. Shreve, 

 of Tucson, Arizona. The two successful es- 

 says were entitled, respectively : " The Pota- 

 mogetons in Relation to Pond Culture " and 

 " An Investigation of the Causes of Autonomic 

 Movements in a Succulent Plant." These an- 

 nual prizes are awarded for the two best es- 

 says submitted on subjects selected by a com- 

 mittee of the society. For the years 1916 and 

 1917 the committee announces that competi- 

 tive essays will be received on " any subject in 

 the field of natural history" thus allowing 

 wide scope.
