Iron ore, found in Plymouth Vermont, is stated 
by Te arte . Clarke, to occur in a vein two or three feet 
wide near the meeting-house. 
Jam not aware that Saratoga Springs have ever been no- 
ticed in the Journal of Science as a locality of Spodumene. 
It occurs there, 1 am told, in abundance; and in colour 
more nearly resembles the Swedish mineral than that of 
Goshen.*

M. Boué, in a letter to Dr. J. W. Wester. 
i “be lately visited the whole chain of the Pyrenees, 
and m are not quite the same as those of Charpentier 
in 1810, and now he nearly agrees with me as to their geolo- 
gical structure "The diahees oe ophive of the Pyrenees are 
veins, very much. resembling those in the transition 
tose rocks, and are of the same age with the sienite. The 
granite is not stratified, nor in beds, but in bed like veins, in 
veins and in columns in the transition slate rocks, which the 
have altered so much as to render them (convert them saan 
neiss and mica slate. The primitive granular limestone of

ed by granite, and the minerals tremolite, garnet, amphi- 
macle, &c. have been eine bart in it in the same way.

I have also visited the whole of the South of France. The 
Garonne and Adour basins are surrounded by Juratic dolo- 
mite, oolite and compact Jura limestone, with green sand
