Bone's Geological and Miscellaneous Observations. 2? 



Sparry Iron ore, found in Plymouth Vermont, is stated 

 by Mr. S. F. Clarke, to occur in a vein two or three feet 

 wide near the meeting-house. 



I am not aware that Saratoga Springs have ever been no- 

 ticed in the Journal of Science as a locality of Spodumene. 

 It occurs there, I am told, in abundance; and in colour 

 more nearly resembles the Swedish mineral than that of 

 Goshen.* 



Akt. VI. — Geological and Miscellaneous Observations, by 

 M. Boue, in a letter to Dr. J. W. WEBSXER.f 



I HAVE lately visited the whole chain of the Pyrenees, 

 and my results 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 diabase or ophite of the Pyrenees are 

 veins, very much resembling those in the transition schis- 

 tose rocks, and are of the same age with the sienite. The 

 granite is npt stratified, rior in beds, but in bed like veins, in 

 veins and in columns in the transition slate rocks, which they 

 have altered so much as to render them (convert them into) 

 gneiss and mica slate. The primitive granular limestone of 

 Charpentier is nothing else than a transition limestone alter- 

 ed by granite, and the minerals tremolite, garnet, amphi- 

 bole, made, &.c. have been produced in it in the same way. 

 (See my memoir in the Annales des Sciences naturales, 

 which takes the place of the Journal de Physique, which is 

 discontinued.) 



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 



* The writer of this notice would be glad to exchange specimens of the 

 spodumene and manganese mentioned above, (and he could add several 

 other of the interesting minerals in the vicinity,) for native or foreign 

 minerals, and especially for geological specimens.

Dear Sir, 



I send you an extract from a letter I have just received from Dr. Boue, 

 believing that the occasional obscurity arising from his writing in a language
