Dr. Charles Denison, a specialist in the 

 treatment of tuberculosis, died at his home in 

 Denver, Col., on January 10. 



Braxton H. Guilbeau, professor of zoology 

 at the Louisiana State University, died on 

 January 16, 1909. He was a graduate of the 

 same institution, and had been in charge of 

 the zoological department for several years. 

 Since 1906, he had been director of the Gulf 

 Biologic Station. Owing to heavy univer- 

 sity work, he was unable to carry on as much 

 research work as he was ambitious of doing. 

 In simimer work at Cornell, he investigated 

 the froth prodiuction of the " Spittle Insects," 

 on which he published a paper in the Ameri- 

 can Naturalist for December, 1908. At the 

 time of his death, he had been engaged for 

 several months investigating the parasites of 

 Plusia trassica, confirming the results of 

 French investigators as to the development of 

 many insects from a single egg. Unfor- 

 tunately this work was left in such a stage 

 that it will be impossible to bring it together 

 for publication. 



Surgeon-General John Edward Tuson, a 

 retired officer of the Indian Medical Service, 

 the author of numerous contributions to med- 

 ical science, died at Eastbourne, on December 

 24, at the age of eighty years. 



Dr. R. Englander, professor of mechanical 

 engineering in the Vienna Technical Institute, 

 has died at the age of fifty-nine years. 



The death is announced of Dr. A. Grigorief, 

 for twenty years secretary of the Imperial 

 Eussian Geographical Society. 



The Darwin anniversary addresses delivered 

 on Darwin Day before the American Associa- 

 tion for the Advancement of Science have all 

 been assembled, and will be published at an 

 early date by Messrs. Henry Holt & Company. 

 The title of the volume will be " Fifty Tears 

 of Darwinism, Modern Aspects of Evolution 

 and the Various Biological Sciences, Centen- 

 nial Addresses in Honor of Charles Darwin 

 before the American Association for the Ad- 

 vancement of Science, Baltimore, Friday, Jan- 

 uary 1, 1909." 



At a meeting of plant pathologists called 

 at Baltimore, December 30, 1908, in connection 



with the meeting of the American Association 

 for the Advancement of Science, Professor A. 

 D. Selby, of the Ohio Experiment Station, was 

 elected temporary chairman, and Mr. Donald 

 Eeddick, temporary secretary. The temporary 

 committee, appointed at Washington, on De- 

 cember 15, consisting of 0. L. Shear, Donald 

 Eeddick and W. A. Orton, presented its report 

 recommending that an organization of Amer- 

 ican plant pathologists be perfected. The 

 report of the committee was accepted and 

 temporary organization was effected by the 

 unanimous election of the following officers: 

 President, Dr. L. E. Jones, Vermont Agricul- 

 tural Experiment Station; Vice-president, 

 Professor A. D. Selby, Ohio Agricultural 

 Experiment Station; Secretary-treasurer, Dr. 

 C. L. Shear, U. S. Department of Agriculture; 

 Oouncilmen, Professor J. B. S. Norton, Mary-

 form a council which is to consider and make 

 recommendations in regard to all questions 

 relating to the permanent organization, policy 

 and affiliation of the society. The next meet- 

 ing will be called at such time and place as 

 may be decided by the council.
