also diamonds ; the other composed of sand, gravel and clay, 
and known under the name Cascalho , often affords much gold, 
and many diamonds . 
19. Matrix of the Brazilian Diamond. — In Mr He u land’s 
splendid collection, there is a Brazilian diamond imbedded 
in brown iron-ore; another, also in brown iron-ore, in the 
possession of M. Schuch, Librarian to the Crown Princess of 
Portugal; and Eschwege has in his own cabinet a mass of brown 
iron-ore, in which there is a diamond in a drusy cavity of a 
green mineral, conjectured to be arseniate of iron. From these 
facts he infers, that the matrix, or original repository, of the 
diamond of Brazil, is brown iron-ore, which occurs in beds of 
slaty quartzose micaceous iron-ore, or in beds composed of iron- 
glance and magnetic iron-ore, named by him Itabirite , both of 
which are subordinate to what he considers as primitive clay-slate. 
20. Human Fossil remains. — Count Razoumaski has lately 
found, associated with remains of elephants, skulls and other 
bones of a race of people, conjectured to be very different from 
those that now people the globe. They seem to have buried 
their dead in hillocks, and all the skulls examined had a most 
remarkably elongated form. Schiottheim, we understand, will 
publish an account of these remains.
