The Group Picture of the fellows of the Geological 
Society of America has recently been distributed to subscrib- 
ers. The picture includes portraits of 189 American geolo- 
gists living since 1889. Of these all but ten are now alive, 
and sixty-six of the present fellows of the society are not- 
included. The central portrait of the group is that of James 
Hall. 
Sir John Willi.am Dawson, the oldest and most eminent 
geologist of Canada, who has been long revered and beloved 
by geologists throughout all the world, died at his home in 
Montreal, November 19th. He had just completed his seventy- 
ninth year, having been born in Pictou, N. S., October 13th, 
1820. He received his education at the College of Pictou, and 
in Edinburgh University. In 1842 he accompanied Sir Charles 
Lyell in his tour of geologic observations through Nova Scotia. 
In 1855 he became the principal of McGill College, Montreal, 
filling also its professorship of natural history. Principal Daw- 
son's energetic and wise direction of this institution continued 
thirty-eight years, to 1893, during which time it advanced to 
the front rank of American universities. In an ensuing number 
we hope to give a sketch of his life and of his services to 
geology as an observer and as an author, which covered a 
period of more than fifty years.
