agriculture nnd forestry, animal industries, and labor, transport, and trade. 

 About two hundred papers and reports were submitted. These were mainly in 

 the first section where the principal topics considered were the culture of cotton 

 and rubber in tropical countrie.s, wheat breeding investigations, tobacco grow- 

 ing, and the Zanzibar clove industry. In section 2 the principal topic was the 

 acclimatization of European cattle in the Tropics. During the congress a 

 special meeting was held of the International Association of Colonial Agricul- 

 ture, at which Prof. Wyndham Dunstan, director of the Imperial Institute, was 

 elected president. 



The International Horticultural Congress was held April 30 to May 3, and

 ticular attention. The principal business transacted was the adoption of the 

 rules promulgated at the 1905 congress at Vienna, with certain necessary addi- 

 tions in the case of horticultural varieties and hybrids. 



Necrology. — Prof. Edouard Van Beueden, the Belgian zoologist, well known 

 for his contributions on embryology and the mechanics of cell division, died 

 April 28, 1910. He was born at Louvain March 5, 1846, and began teaching 

 zoology at IJege in 1871. Three years later he was promoted to the grade of 

 professeur ordinaire, a position which he held the remainder of his life. 

 Though his researches were in the realm of pure science, the results which he 

 obtained in-ovided the foundation for many current investigations on the prin- 

 ciples of breeding. His first paper, which was published in 1869, was on the 

 composition and signification of the egg. His later cytological studies rank 

 with those of Hertwig and Strassburger in importance and he made many con- 

 tributions to the knowledge of the tissues of the developing embryo of many 

 species of animals. In his studies of intestinal worms he was the first to show 

 that for the ovum the chromatic threads are a portion of the existing network 

 of the nucleus and that the two-daughter chromosomes are alike and pass to 

 the opposite holes of the spindle. He discovered the centrosphere and was the 

 first to demonstrate the importance of the centrosome in cell division. Per- 

 haps his most important work was the demonstration of the halving of the 

 number of chromosomes in gametogenesis. He founded and edited the Archives 

 de Biologic, in which some of his most important work was published. Pro- 

 fessor Van Beneden was the recipient of many honors from European universi- 

 ties and scientific societies. 



Hon. A. C. Bird, dairy and food commissioner for Michigan since 1905, died 

 May 27, at the age of 46 years. He was a graduate of the Michigan Agricul- 

 tural College and for several years a member of its governing board.
