George Lawson, Professor in Dalhousie College, Halifax, 

 Nova Scotia, died at his home on the evening of November 10. 

 He was born in Scotland, Oct. 12, 1827. He was educated at a 

 private school. After a few years of study by himself, in which 

 he devoted a good deal of attention to law, he entered the Uni- 

 versity of Edinburgh, and at once began active work in Natural 

 Science, giving much of his time to Botany. He was, for a time, 

 Curator of the Herbarium at the University and assistant to the 

 Professor of Botany. In 1857 he took the degree of Ph.D. at 

 the University of Giessen, and in the following year came to 

 Canada as professor of chemistry and natural history in Queen's 

 University, Kingston, Ontario. In 1863 he accepted the profes- 

 sorship of chemistry and natural history in Dalhousie College. 

 From the first year of his residence in Nova Scotia he engaged in 

 the development of the agriculture of the Province, and was the 

 secretary of the Board of Agriculture till 1885. In that year the 

 work of the board was transferred to the provincial government 

 and Dr. Lawson became Secretary of Agriculture for the Province. 



His contributions to science have been published chiefly in the 

 Transactions of the Botanical Society of Edinburgh, the Royal 

 Society of Canada, and the Nova Scotia Institute of Science. 

 His activity in bringing before the farmers of the province the 

 latest and most trustworthy intelligence in agricultural matters 

 was unabated up to the last of his life. Professor Lawson was a 

 member of many learned societies in America and Europe, and 

 was for a time President of the Royal Society of Canada, g. l. g. 



M. S. Bebb. — At the moment of going to press, we learn that 

 M. S. Bebb, of Rockford, Illinois, died in California, on the 5th 

 of December. Although for some years in enfeebled health, he 

 did not relinquish until recently the study of his favorite plants, 

 the willows. We hope to give in a subsequent number of this 

 journal some account of the useful life of this botanist, who has 

 endeared himself to his correspondents everywhere. g. l. g. 



Don Antonio del Castillo, founder and director of the Geo- 

 logical Survey of Mexico, died on the 27th day of October, 1895, 

 in the city of Mexico.
