the condrodite* from Warwick, which I find to be a beauti- 
ful variety of pargasite, such as is found at Pargas, in Fin- 
land, where it is also accompanied with condrodite, rhomb 
spar, and mica ; and it is also remarkable that all these sub- 
stances are found at Parga, as in America, in the same 
geognostic situation, and accompanied with the same mine- 
rals. The metallic substance which is found associated with 
spinelle in massive eondrodite at Warwick; is undoubtedly

titan. fer. oxidé, a mineral not unfrequently found under the 
same circumstances at Arendal, i orway.” The same 
mineralogist observes, ‘‘ that, as to your Nuttallite, it seems 
to me to be extremely like a variety of compact scapolite, “its 
erystalization and principal external characters being exactly 
like the same species of scapolite which we find in Norway.” 
It may now be permitted me to make a few observations 
in explanation of the above remarks of Mr. Von Struve. 
The apple green substance imbedded in carbonate of lime with 
Brucite, found near Warwick, had been previously noticed 
e, and was suspected to be a rare mineral, called pyrallo- 
lite, found also in Finland ; but its real character remained 
undetermined, till,I received the above account, and on re- 
ferring to a specimen of pargasite from Finland, in my cabi- 
! find it perfectly similar, showing how useful it is to 
have on such occasions, an extensive variety of specimens te
