The preceding review of the scientific work of Prof. Hartt, though 

 very incomplete, indicates how untiring must have been his industry. 

 In order to judge of the real character and value of his investiga- 

 tions, we must refer to his publications. These, however, give us but 

 a glimpse of the vast store of knowledge he had accumulated. He 

 has left a number of volumes in manuscript which, when published, 

 will add greatly to his scientific standing, by making known to the 

 world the variety and excellence of the work he had accomplished. 

 Until then, only the few scientific associates who knew him inti- 

 mately can award to him his just merits. 



Hartt possessed in a high degree the qualities requisite to form a 

 successful leader. He could plan effectively, directing his scattered 

 forces with little effort and to the best advantage. He displayed the 

 greatest skill in utilizing the diverse results from many sources, never, 

 however, losing sight of the grand whole he was seeking to build up. 

 He belonged to the modern school of Evolution, the theories of which 

 had been sufficiently proved to him by many of his studies, and from 

 these he obtained his great inspiration. Judging from his brilliant 

 beginning, we are confident in asserting that, had he lived, he would 

 have won for himself a place by the side of such investigators as De 

 le Beche, Murchison, Logan and others, like whom he was a pioneer 

 in the special field of research he had entered. In the following re- 

 port we have in his own words an account of his Brazilian work from 

 July 1, 1877, to January 1, 1878. 



" During the past six months the members of the Geological Com- 

 mission have been quite exclusively employed in laboratory work in 

 the building of the Commission in the Corte, the aim being to obtain 

 before the end of the year the largest possible results from the dis- 

 cussion of the material collected to illustrate the geology of the re- 

 gion explored, and at the same time to put this material in the best 

 possible order. 



" It is but seven months since the Commission entered the house 

 it now occupies, and has had space and facilities for opening 

 and arranging its collections of rocks, fossils, minerals, etc. In 

 April last it occupied a single room in the building of the Carta Ge-
