Charles Frederick Hartt. 125 



carefully inspected the building and work of the Commis- 

 sion. He showed a just appreciation of the value of the 

 new Museum of Geology, both to his own country and to 

 the world at large ; he was generous in his words of praise 

 to the talented chief, who had so dearly earned them, and 

 declared that the work should go on. 



In the beginning of the following year, an entire change 

 was made in the Ministry of Brazil, and before the several 

 departments had been entirely re-organized, and the appro- 

 priations determined upon, Professor Hartt died. There 

 was no one to succeed him, and his large collections were 

 placed in the care of the National Museum at Eio de Jan- 

 eiro. It is expected that steps will be taken by the Brazil- 

 ian Government at an early date, toward publishing the 

 many reports which were finished under the direction of 

 Prof. Hartt. 



It would appear that before the researches of Professor 

 Hartt, the systematic geology of vast areas of Brazil, was 

 an utter blank. The Carboniferous system was known to 

 exist in the South of Brazil, and some Palajozoic fossils had 

 been found on the Tapajos E. in the North of the Empire ; 

 the Cretaceous formation had been recognized on the eastern 

 coast, but it remained for Hartt to exhibit the general geo- 

 logic structure of extensive areas of the Empire, and to 

 recognize wide spread formations of Upper Silurian, Devo- 

 nian, Carboniferous and Triassic (?) age. He also divided 

 the vast areas of metamorphic rocks in Central Brazil into 

 Eozoic and Lower Silurian by their lithological aspect and 

 other characters. 



Nor did he confine his studies to Geology alone, for in 

 addition to voluminous reports on this subject, he had the 

 following works nearly or quite ready for publication 

 I. Brazilian Antiquities, — about 500 pages, 4 to. 

 II. Mythology of the Brazilian Indians, — about 300 

 pages 4 to. 



III. Grammar, Dictionary &c. of the Tupe" Language, 



400 pages. 



IV. An Album — of about 100 photographs, illustrating 



the country, people &c. of the Lower Amazonas. 

 With about 100 pages of text.
