Charles Frederick Hartt,

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, towmrd 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 Pala30zoic 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 Upj^er Silurian, Devo- 
nian, Carboniferous and Triassic (?) age. He also divided 
the vast areas of metamorphic rocks in Central Brazil into 
Eozoic and Low^er Silurian by their lithological asj^ect 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 Tup^ Language, 
400 pages. 
ly. An Album — of about 100 photographs, illustrating 
the country, people &c. of the Lower Amazonas. 
With about 100 pages of text.
