The following tribuies to the memory of Professor Hartt, exi-ress, 



IN A measure, the DEEP KEELING OF SORROW OCCASIONED BY THE NEWS OF 

 HIS UNTIMELY DEATH : 



Principal J. W. Dawson, of McGill College, Montreal, 

 Canada, in his annual address as President, before the 

 Natural History Society of Montreal, May 18, 1878, 

 spoke as follows : 



" The second name, which it becomes me to mention here, is that of a man 

 less known to many of you, but intimately known to me, and whom we have 

 the right to claim as a Canadian geologist, and one of the highest standing — 

 Charles Frederick Hartt, late Professor of Geology in Cornell University, 

 and Director of the Geological Survey of Brazil, who died at Rio de Janeiro 

 on the i8th of March last, at the early age of thirty-eight years. He was a 

 native of Nova Scotia ; and at Horton, in that Province, where he studied at 

 Acadia College, and while still a student, he became known to me as a dili- 

 gent and successful collector of fossils of the Lower Carboniferous rocks. 

 He subsequently engaged in educational work in St. John, and with his 

 friend, Mr. Matthew, had the honor of first rendering intelligible the com|)li- 

 cated geology of that district, and of discovering and almost exhausting its 

 rich Devonian Flora and Fauna. The collection and determination of the 

 Cambrian fossils, of what is now known as the Acadian group, and the ex- 

 cavation of the numerous fossil plants of the Devonian of the same district, 

 constitute, in my judgment, two of the most important advances ever made 

 in the Palfeontology of Eastern America, and are even yet bearing fruit. It 

 was my good fortune to be able to aid and encourage Mr. Hartt in these 

 earlier efforts, to determine his Lower Carboniferous and Devonian plants, 

 and to afford him, in my ' Acadian Geology,' a medium of publication for 

 his Primordial fossils. Acting under my advice, Mr. Hartt, in order to per- 

 fect his knowledge of palaeontology, entered the school at that time recently 

 established b)' Agassiz, at Cambridge. This led to his appointment to a 

 chair of geology first at Vassar College, and subsequently at Cornell, and 

 also to his connection with Brazil, which began with his being attached in 

 1S65 to the 'Thayer Expedition' to that country, under Prof. Agassiz. The 

 magnificent opening for geological work in Brazil seems to have fascinated 

 his mind, and I remember well the enthusiasm with which he wrote to me, 

 at a subsequent time, of the almost identical fauna and flora of the Brazilian 

 Coal-measures with those he had in earlier days explored in Nova Scotia. In 

 1870 he returned to that country with an expedition from Cornell, and in 

 1875 he was appointed to the direction of the Survey, then instituted by the 

 Brazilian government, having already had a semi-official connection with the 

 government for about a year. In the three }-ears in which he worked in con- 

 nection with the Brazilian government, he had explored and mapped large 

 districts of the country, had accumulated a valuable geological museum,
