by to Ceard, without acknowledging the sympathy shown by 
the President of the Province, Senhor Homem de Mello, in 
the objects of the expedition. Mr. Agassiz has received a col- 
lection of palms and fishes, the directions for which he had 
given before starting for the Serra, but the expenses of 
which are defrayed by the President, who insists upon their 
being received as a contribution from the province. Mr. 
Agassiz is also greatly indebted to Senhor Felice, at whose 
house we have lodged, for efficient help in collecting, and to 
Senhor Cicero de Lima for a collection of fishes and insects 
from the interior. I conclude this chapter with a few pas- 
sages from notes made by Mr. Agassiz during his examina- 
tion of the Serra of Aratanha and the site of Pacatuba. 
" I spent the rest of the day in a special examination of 
the right lateral moraine, and part of the front moraine of 
the glacier of Pacatuba ; my object was especially to ascer- 
tain whether what appeared a moraine at first might not, 
after all, be a spur of the serra, decomposed in place. I as- 
cended the ridge to its very origin, and there crossed into an 
adjoining depression, immediately below the Sitio of Captain 
Henriquez, where I found another glacier bottom of smaller 
dimensions, the ice of which probably never reached the 
plain. Everywhere in the ridges encircling these depres- 
sions the loose materials and large boulders are so accumu- 
lated and embedded in clay or sand that their morainic 
character is unmistakable. Occasionally, where a ledge 
of the underlying rock crops out, in places where the drift 
has been removed by denudation, the difference between the 
moraine and the rock decomposed in place is recognized at 
once. It is equally easy to distinguish the boulders which 
here and there have rolled down from the mountain and 
stopped against the moraine. The three things are side by
