chemical and mineralogical details of the economic geology of a vasl re- 

 gion, and supplied to a great extent the Lithological basis for a classifica- 

 tion of its rocks. At the same time he was developing a system ofchemic 

 geology based very largely on his own original investigations. Logan and

 with a wide and growing field experience; the other an able chemist and 

 mineralogist, with a versatile and suggestive mind. Both profited by 

 this combination, which contributed greatly to the successful prosecu- 

 tion of the Survey. During- this period he also occupied the chair of 

 chemistry at the Laval University, at Quebec, from 1856 to 1862 and at 

 McGill University, Montreal, from 1862 to 1868. 



From 1S72 to 1878 he was Professor of Geology at the Massachusetts 

 Institute of Technology. He was a juror at the Paris Expositions in 

 185(3 and 1857, and there came into personal contact with the geologists 

 of England and the continent. In 1859 he was elected a Fellow of the 

 Royal Society of London, and a member of the National Academy of 

 Sciences in 1873. In 1S81 the University of Cambridge conferred on him 

 the degree of LL. D. . He was acting President of the American Asso- 

 ciation for the Advancement of Science in 1871, President in 1877 of the 

 Institute of Mining Engineers, and the first elected President of the 

 Royal Society oi Canada. It is to his motion, made to the American 

 Association for the Advancement of Science in 1876, that we owe the 

 plan for an International Geological Congress, and he held office at sev- 

 eral of the meetings of this body. In 1855 the French government 

 made him a Chevalier of the Legion of Plonor. and later an officer of the 

 ~ame order, and after the Bologna meeting of the Geological Congress 

 he received the order of Saint Mauritius and of Saint Lazarus. 



Dr Hunt was a most indefatigable worker and reader of a wide range 

 of literature, and seems to have had a wonderfully retentive memory. 

 In s] .caking, his addresses and papers were given without notes and were 

 remarkable for their ready fluency and directness of diction, as veil as 

 for logical arrangement of ideas. The number of his published contribu- 

 tions to scientific literature is very large, but the more important part of 

 his work is embodied in the few volumes which he published: " Chemical 

 and Geological Essays," 1874 and 1878; "Azoic Pocks," 1878 : "Mineral 

 Physiology and Physiography," 1886; "A New Basis for Chemistry." 

 L887, and " Mineralogy according to a Natural System." 1891. 



Mr Douglas informs us that Dr Hunt was a good mathematician and 

 had an excellent acquaintance with botany, in which his interest lay 

 more, however, on the esthetic and economic than on the purely sys- 

 tematic side. 1 le acquired such a knowledge of Drench as enabled him 

 to speak it equally fluently with English. Indeed, he was a remarkable
