examined. The principal points to be investigated are the fol- 
lowing : 
1st. The character and distribution of the Palzeozoic rocks bor- 
dering the valley on both sides. Last summer he found Carbonif- 
erous rocks on the Tapajos, and Devonian beds near Monte Alegre. 
More complete suites of the fossils afforded by both these forma- 
tions will be made, so that the faune of the Carboniferous and 
Devonian of Tropical America may be illustrated and compared 
with those of North America and Europe. 
2d. A search for Mesozoic rocks will be continued, none having 
yet been discovered east of the Puris. 
3d. The Tertiary beds forming the Table topped hills will be 
carefully studied at Almeyrim and the Serra da Paranáguára, and 
the height of these hills will be measured. 
4th. The deposits of the lower plain will be reéxamined, and in 
this connection a journey will be undertaken across the Island of 
Marajó. 
5th. The shell banks, terraces, etc., on the borders of the val- 
ley will be explored to determine, if possible, the character and 
amount of the last uprise of the Amazonian region. 
6th. The Indian mounds of Marajó will be explored. 
7th. He will employ native guides, and continue the study of 
the Lingoa Geral, or Modern Northern Tupi. 
- Mr. Orville A. Derby, who distinguished himself on Prof. Hartt’s 
last expedition, accompanies Prof. Hartt as special assistant. - 
The latter has already had several months’ experience in photog- 
raphy and goes furnished with apparatus for taking a series of 
views with which to illustrate his next volume. A popular illus- 
trated sketch of the journey will appear immediately after his 
return, as we understand, in the columns of ‘‘ Every Saturday.” 
As extensive a collection of zoological, geological and ethnolog- 
ical specimens will be made as possible. 
The expedition, though in the interest of Cornell University, 
has been’ privately gotten up. The greater part of the fund has 
been furnished by Col. Edwin Morgan of Aurora, N. Y., who also 
bore a large part of the expenses of his last expedition, and, in 
recognition of the kindness of this gentleman, Prof. Hartt has 
given to this exploration the name of the Morean EXPEDITION. 
Prof. Hartt has received considerable pecuniary aid from private 
individuals, and the Peabody Museum of Archæology has placed
