which had inaugurated the Survey was gone, and further 
investigation of the physical structure of Brazil with 
governmental aid is left to the enterprise of another 
generation. 
Since Professor Hartt’s death, two volumes of the 
Archives of the National Museum of Brazil have been pub- 
lished, which testify to the extent of his labors. The first 
(No. YI.) contains an account of the Archaeology and Eth- 
nology of the tribes of the Amazonas, based on observations 
made by Prof. Hartt and his assistants on the shell-heaps, 
the cemeteries and the artificial mounds of that region, and 
contains descriptions and figures of the articles found in 
these repositories of the relics of its pre-historic people. It 
contains also an essay on the origin of art, and the evolu- 
tion of ornamentation as exhibited by their pottery &c. ; as 
well as an account of certain ti-ibes of the region and their 
mythology. 
In the remainder of the volume the result of Prof. Hartt’s 
work stands out on many a page, especially in the very in- 
teresting memoir by Dr. Ladislaus Netto on the Archaeology 
of Brazil. The material collected under Prof. Hartt’s di- 
rection at the island of Mai-ajo and at Maraca, are largely 
used by Dr. Netto in illustrating his memoir. 
The succeeding volume of the Annals of the Museum 
(No. YII.) is devoted to a description of the Cretaceous 
Mollusca of Brazil by Dr. C. A. White of the geological sur- 
vey of the United States. This voluminous memoir, pub- 
lished in Portuguese and English, is also based on the ma- 
terial collected under Prof. Hartt, when in charge of the 
geological survey of Brazil. 
Several years after his death, the remains of this devoted 
man were i-emoved from Brazil to Buffalo, N. Y., the home 
of his widow, where they now lie in a cemetry on the shore 
of Lake Erie. 
Since his death, a tablet to his memory has been placed 
in the library of Acadia College (his “ alma mater ”). This 
tablet was set up by his classmates in commemoration of 
his great services to Science. On the unveiling of the monu-
