thorough study of the coral reefs of the coast of Pernambuco. He also 

 amassed many facts regarding the language, manners and customs of the 

 Tupis, Guaranis and other Indian tribes, and Brazilian archseology. 



"Professor Hartt, besides being a geologist, palaeontologist and zoologist, 

 was a capital linguist and philologist. He had powers of rapid acquisition 

 and great versatility. He was a person of warm sympathies, and of a cheer- 

 ful, light-hearted spirit that endeared him to all with whom he came in con- 

 tact. To the readers of this journal, to which he often contributed on 

 geological and archseological subjects, his powers of exposition are well 

 known. His death is a serious blow to American Science. All will deplore 

 his loss; his memory will be cherished by his fellow-students and associates 

 who knew him best and appreciated his moral worth and his intellectual and 

 scientific attainments." 



Prof. James D. Dana, in "The American Journal of 

 Science and Arts," April, 1878: 



" Professor Hartt, according to a telegram from Rio Janeiro, died of 

 yellow fever soon after the middle of March. Prof. Hartt was born in 1840, 

 at Fredericton, N. B. In his youth he evinced a taste for geology, and dis- 

 covered at St. John many fossil plants, and the oldest specimens of fossilized 

 insects then known. He studied from 1862 to 1S65, under Agassiz, at 

 Cambridge, and accompanied that eminent scientist to Brazil as geologist of 

 his expedition. On his return he was appointed Professor of Geology 

 and Physical Geography at Cornell University. After his first visit to 

 Brazil, Professor Hartt acquired a thorough knowledge of the Portuguese 

 language, and that Empire became his favorite field of study. He returned 

 three times and zealously explored the northern provinces, giving most 

 attention to the valley of the Amazon. During one of these expeditions, 

 undertaken under the auspices of the Hon. Edwin D. Morgan, of New 

 York, he sent home an interesting series of letters for publication. Papers 

 containing some of the geological results of these expeditions are noticed in 

 this journal ; in volumes i, iv, vii, viii and x, of the third series (iSji-'jsf- 

 In May, of 1875, the Brazilian Government placed Professor Hartt in charge 

 of the Geological Survey of the Empire, and gave him a liberal salary ; 

 since then he has been carrying forward this great work. The results thus 

 far obtained have been only partially published. A translation of his first 

 Report of Progress, made by Professor T. B. Comstock, is contained in this 

 Journal, in vol. xi, 1876, and a brief announcement of further discoveries in 

 vol. xii. In 1870, he published his principal work, 'The Geology and 

 Physical Geography of Brazil.' He felt at home in Rio. where he enjoyed 

 excellent health, and was greatly esteemed. His famil}' reside at Buffalo, 

 N. Y. His death is a great loss to the scientific world."
