Miscellaneous Localities of Minerals, 55 



14. Siliceous Oxide of Manganese, at Cummington, and 

 Plainfield, at the latter place in considerable plenty. It is 

 of a light but very lively rose red color with some lustre, 

 has a structure somewhat granular, is translucent at the 

 edges, and takes a fine polish. It is associated with the 

 gray oxide ; and around both the black oxide generally 

 forms an envelope. 



15. Red Oxide of Titanium, in quartz, at Whitingham, 

 Vermont. H. M. VVells, 



15. Kyanite, in small quantities at Cummington. The 

 crystals are large and well defined, the color lively and del- 

 icate. It occurs in mica-slate, and is associated with 

 quartz, garnets and black mica. 



16. Red Oxide of Titanium, in good crystals is found at 

 the same place, and sometimes in the same rock. 



17. Actynoiite, in the north part of Windsor. The 

 crystals, which are large and elegant, occur in fascicular 

 or radiated groups, or are confusedly intermixed. They 

 are of a deep green colour with shining surfaces. The 

 actynolite at this place is often associated with chlorite. 



18. Sulphuret of Iron, finely crystallized in Quartz at 

 Windsor and Savoy. 



Magnetic Oxide of Iron, at Cummington. 



19. Red Oxide of Titanium, well crystallized, at Plain- 

 field. 



20. Siliceous Breccia, uncommonly beautiful, at Cum- 

 mington. It is composed of well cemented angular frag- 

 ments of quartz, varying much in size and often with cavi- 

 ties between them. 



21. Fluate of Lime and Rubellite, have been discovered 

 at Bellows Falls, by Dr. H. M. Wells, and 



22. Sulphate of Iron, at Adams, by Henry P. Phillips. 



23. Molybdena, in a granite rock, Goshen, Mass. 



Correction. — The white augite mentioned page 233, Vol. 

 VIII, is, I believe, spodumene.
