In Sussex cont in N ew-Jersey, that variety of tita- 
nium, which is called sphene, or titan. siliceo-caleaire, is 
found in an aggregate of hornblende and feldspar, which 
contains abundance of magneticiron ore. Following the same 
range of mountains into Orange county, in the state of New- 
York, sphene is of frequent oceurrence in the same forma- 
tion, ead associated as at Arendal, with augite, ‘sahlite, sca- 
polite and amphibole. At Cold Springs, where a part ofa 
mountain has been excavated to construct a road on the banks 
of the Hudson, specimens of sphene have been discovered, of 
uncommon size and Beanty, imbedded in compact ae 
and sablite ; and at West Point, similar specimens have bee 
found with the same associations. Crystals of a shomboidal 
_form, of alight brown colour, and several inches in length, 
have been discovered in this locality, in every respect similar 
to those from Norway, and peenepeny ing the same spec ies 
of minerals. Titdhiferous oxyd of iron, is of more frequent 
occurrence than is generally suspected 3 in those districts which 
contain magnetic oxyd oO iro nat is said to be found asso- 
Gated with this mineral in Norway, and I have met with 
every Maid A of the ferruginous oxyd of titanium, wherever 
I have traced extensive beds of magnetic iren ore. ‘On lake 
{ plain in particular, near Crownpoint, it is in “ete 
Saree: ; and the nigrine and iserine there have so great a 
i Blance to some varieties of magnetic iron ore, that I Rave 
‘known it mistaken for such, Seti even attempts made 
smelt it for iron, but without success, owing to its infusibili- 
ty. indeed, some of the ores of iron in that district are so 
co with titanium, that it renders them very refractory 
in the yatta which may account for the frequent failures 
which are met with in fusing such ores. 
There is scarcely any part of Europe where a greater va- 
riety of augites are found, than in Norwa en ; nor 
could I find any class of minerals in which ihe simtlitude be- 
a the apecenens from those countries and America, af-
