" The Devonian System in Canada." Being an address by J. F. 

 Whiteaves, F.G.S., Palseontologist and Zoologist of the Geological 

 Survey of Canada, as Vice-President and Chairman of Section E 

 (Geology and Geography) of the American Association for the Advance- 

 ment of Science. Delivered August 21st, 1899. Published as separate 

 by Amer. Assoc. Adv. Sc, 48th Ann. (Columbus meeting). 31 pp.

 Whiteaves gives the views of Dr. Abram Gesner, Sir Wm. Dawson, 

 Dr. Honeyman, Dr. R. W^. Ells and Mr. Hugh Fletcher without com- 

 ments. The views of Prof. David White, of the U.S. National Museum 

 at Washington, of Mr. Robert Kidstoii, of Stirling, Scotland, on 

 certain fossiliferous rock-formatious occurring uncoiiformably below 

 the marine carboniferous limestones of Eastern Canada, are added as 

 those of specialists who base their opinions upon the evidence afforded 

 by the fossil organic remains entombed in the rocky formations, which 

 by Gesner, Fletcher and Ells are called Devonian, and by Sir Wm. 

 Dawson and the writer as Carboniferous. 



On independent grounds Dr. White and Mr. Kidston corroborated the
