[N. S. Vol. XXX. No. 772 



recent meeting in Denver, August 26 to 28, 

 1909. 



Some anxiety is caused by the failure to 

 receive news from Professor C. K. Leith, of 

 the University of Wisconsin, who, with Mr. 

 Hugh M. Eoberts and Mr. Francis S. Adams, 

 has been making geological explorations in 

 the neighborhood of Hudson Bay. No word 

 has been received from them since their de- 

 parture last June, and it is thought that they 

 may be compelled to spend the winter in the 

 north. 



Professor A. S. Hitchcock, systematic 

 agrostologist of the U. S. Department of Agri- 

 culture, has returned to Washington after 

 four months spent in Alaska and the Yukon 

 District studying the grasses of the region. 

 The greater part of the work was done in the 

 valley of the Yiikon. Large collections repre- 

 senting the rich grass flora of the country 

 were made for the National Herbarium. 



Mr. Carlos Guerrero, of the Argentine 

 Republic, is visiting this country to study 

 agricultural methods. 



Dr. John 0. Willis, director of the Royal 

 Botanic Gardens of Ceylon, will give a course 

 of four lectures on " Tropical Agriculture, 

 with Special Reference to Economic Prob- 

 lems," at Harvard University, on October 12, 

 14, 16 and 19. 



Dr. W. B. Cannon, professor of physiology 

 in the Harvard School, lectured before the 

 Middletown Scientific Association on October 

 12, his subject being " Digestive Processes and 

 the Influence of the Emotions upon Them." 



Dr. Charles R. Barnes, professor of plant 

 physiology at the University of Chicago, lec- 

 tures before the Geographical Society of Chi- 

 cago on October 15, on " Mexican Plants and 

 People." 



The subject of Professor Osier's address at 

 the London School of Tropical Medicine, 

 which is to be delivered on October 28, is 

 " The Nation and the Tropics." 



At University College, London, public in- 

 troductory lectures were given by Sir William 

 Ramsay, on " Radium Emanation : one of the 

 Argon Lines of Gases," and by Professor J. A. 



Fleming, on " Electrical Liventions and the 

 Training of Electrical Engineers." 



Washington Irving Stringham, A.B. (Har- 

 vard '7Y), Ph.D. (Johns Hopkins "SO), pro- 

 fessor of mathematics in the University of 

 California since 1882, appointed acting-presi- 

 dent of the university during the president's 

 leave of absence, died on October 5, at the age 

 of fifty-two years. 



Leonard Pearson, M.D., since 1891 pro- 

 fessor of veterinary medicine in the Univer- 

 sity of Pennsylvania, and since 189Y dean of 

 the veterinary school, knovm for his work on 

 tuberculosis among cattle, died on September 

 20 at the age of forty-one years. 



Professor Anton Dohrn, whose death we 

 were compelled to announce last week, died at 

 Munich, on September 26. He was sixty- 

 eight years of age. The funeral, after crema- 

 tion, took place at Jena on October 3. 



At the meeting of the Chemists' Club, New 

 York, held on October 8, it was announced 

 that a Chemists' Building Company had been 

 organized, for the purpose of acquiring a plot 

 of ground, 56 X 100, at 50 East 41st Street, 

 and erecting thereon a large scientific build- 

 ing, the lower floors of which are to be rented 

 to the Chemists' Club on a long lease, and 

 contain scientific meeting rooms, a library 

 and a museum, as well as the ordinary facili- 

 ties required by a social organization, inclu- 

 ding sleeping apartments for its members. 

 The upper floors of the building are to be 

 rented for scientific laboratories for commer- 

 cial and research work in chemistry and 

 allied sciences. For the past eleven years the 

 Chemists' Club has been located at 108 West 

 55th Street, and various chemical societies 

 have used its meeting room, which has gradu- 

 ally proved inadequate to meet the growth of 

 these organizations. 



At the closing meeting of the International 

 Geodetic Association, held at Cambridge, 

 there were made several announcements of 

 scientific interest. According to the report in 

 the London Times Lieutenant-Colonel Bur- 

 rard, representing India, said that recent 

 levelling operations in India showed that the 

 Siwalik range gained a few centimeters in
