SUPPLEMENT TO THE AUTHOR'S MINERAL LEXICON OF 

 FRANKLIN, HAMPSHIRE, AND HAMPDEN COUNTIES.^ 



1895. Albite. Blaudford; Osborn's soapstone quarry. 



Fire, fresh, white-transluceut crystals au inch across. In flat plates from 

 growth iu fissures aud large developmeut of basal plane, which is deeply striate 

 parallel to the intersection edges with the i)rimary prism. 



Twinned by the pericliue law and with few plates interposed according to 

 the albite law. 



Forms present, b (010), c (001), m (110), ;/ (450),. /(ISO), : (150), M (110), k (150), 

 « (130), .F (101), .(/ (112), e (021), p (111), o (111). (See p. 85.) 



1896. Albite. Chester. 



At the adit of the new mine opened north of the road opposite the old 

 Emery mine. The mineral occurs in perfect simple white crystals an inch 

 in length. They inclose titanite and are coated with prochlorite. 



1892. Allanite. Belchertown. 



Cited from Belchertown. E. S. Dana. Sys. Min., p. 1058. 



1892. Ankerite. Middlelield. 



E. S. Dana. Sys. Min. Localities, p. 1059. 



Doubtless from the steatite bed. All the specimens I have examined from 

 these beds were dolomite. 



1892. Anthophyllite. Blandford. 



B. S. Dana. Sys. Min., p. 1058. 



This is the brown actinolite from Osboru's soapstone quarry. 



1892. Anthophyllite. Chesterfield. 



E. S. Dana. Sys. Min., p. 1058. 



This is the hair-brown, coarsely fibrous mineral from the bluff above Burnell's 

 pond, which is identical with the cummingtonite or amphibole-anthophyllite 

 occurring in Cummington, a little way farther north, in the Conway schists.
