Quarterly Journal of the Geological Society, The Geological Society, 

 the IVansactions of the Royal Society of Canada, the Journal of 

 Geology (Chicago), and in other American publications. 



But Dr. Dawson's services to Science and the State have not been 

 limited to Geology, for in 1891 he was appointed one of H. M. 

 Behring Sea Commissioners, and made an extended cruise in that 

 sea, investigating matters relating to the life and history of the 

 fur-seaL He made use also of the opportunity to observe some 

 interesting geological facts on the coasts and islands passed by, 

 which were afterwards published in the Bulletin of the Geological 

 Society of America (1891). Afterwards Dr. Dawson took part, as 

 one of the Commissioners, in the Conferences held at Washington, 

 and he subsequently assisted in the preparation of the British Case 

 which was laid before the Behring Sea Arbitration Commission at 

 Paris. 



The value of Dr. Dawson's work has been duly recognized by 

 geologists in this country as well as in Canada. The Geological 

 Society of London awarded to him the Bigsby Medal in 1891, and 

 in the same year he was elected a Fellow of the Eoyal Society. For 

 his services on the Behring Sea Commission he also received the 

 title of C.M.G. He served as President of the Royal Society of 

 Canada in 1891, and his Presidential Address for that year embodies 

 a careful review of what has been done, and what should be 

 attempted, in the various branches of science in Canada. We are 

 glad also to state that Dr. Dawson is to be the recipient this year 

 of a gold medal from the Royal Geographical Society, a well- 

 deserved honour. 



The Geological Survey of Canada is fortunate in having so able 

 a geologist as Dr. Dawson for its Director. In advancing our know- 

 ledge of the geology of that vast region and thereby contributing to 

 its economic prosperity and development. Dr. Dawson will, we are 

 confident, successfully carry forward the work of his eminent pre- 

 decessors Logan and Selwyn. G. J. Hinde.^
