Institution, of Washington, during September 

 and October determined the three magnetic 

 elements (declination, dip and intensity) at 

 70 stations in the portion of Canada bounded 

 by the parallels of latitude 42° and 49° and 

 the meridians of longitude 65° and 105° west. 

 In this region very few observations had pre- 

 viously been made. With the completion of this 

 work it is now possible to extend the magnetic 

 maps for the United States up to the forty- 

 ninth parallel across the entire continent. 

 The standard magnetic instruments of the 

 Toronto Magnetic Observatory were likewise 

 compared with those at the Cheltenham Mag- 

 netic Observatory, making it possible thereby 

 to reduce all the magnetic work in the 

 United States and Canada to the same stand- 

 ard. Through the courtesy of Professor 

 Stupart, director of the Canadian Meteorolog- 

 ical Service, the Toronto Magnetic Observa- 

 tory, situated at Agincourt, was made avail- 

 able as the base station for the work under- 

 taken by the Carnegie Institution. 



Professor Savas, of the University of 

 Athens, has recently visited the Liverpool 

 School of Tropical Medicine with view to ob-

 last year, 960,000 cases of malaria.

 East Asiatic and Malaysian races. 



The annual dinner of the New York Asso- 

 ciation of Biology Teachers will be held at the

 G. Conklin, head of the department of zoology, 

 of the University of Pennsylvania, will be the 

 guest of the association and will make an ad- 

 dress on ' Biology and Life.' 



Professor Walther Nernst, professor of 

 physical chemistry in the University of Ber- 

 lin, delivered a lecture at the Johns Hopkins 

 University, on October 19, before the graduate 

 students in physics and chemistry. He gave 

 an account of his work on the dissociation of 

 water-vapor at high temperatures.

 York Academy of Sciences at the American 

 Museum of Natural History, on October 29,

 nection with the British Museum of Natural 

 History will be given this year by Dr. R. F. 

 Scharff. The course of twelve lectures, which 

 begins on November 5, has as its subject ' The 

 Geological History of the European Fauna.'
