the micaceous part, even in powder, is unaffected by the 
magnet. 
Green Foliated Tale, from Windham, Vermont.—This 
mineral, communicated by Professor Hall and by Mr. 
Bradley of Yale College, is not inferior in beauty to the 
Venetian talc, and is well worthy of the attention of mine- 
ralogists. Good specimens have been transmitted by Dr. 
Jacob Porter from the soap stone quarry at Middlefield, 
Mass. and by Mr. Thomas H. Webb from Smithfield, R. I. 
The latter has a silvery appearance. 
Actynolite.—This mineral well crystalized and of good 
colours, occurs with the talc at Windham, Vermont, also at 
Saybrook, (Professor Hare,) and at Middlefield, (Mr. Cole-

Porter.) The first mentioned, is as beautiful as that of 
Tyrolese Alps, and much resembles it.

very excellent quality, has been recently discovered by Mr. 
Calvin Pease, of Hillsdale, Columbia County, N.¥. The 
specimens are apparently very pure, and of such size and 
—— as imply a valuable mine of this substance. Mr. 
Pease does not however, say in his letter where the mine 
is situated—we presume in his vicinity.
