 In two or three instances the secondary greenstone is said to terminate in 

 Northfield-butforNorthfield,insert"Gilla little south of the meeting house." 

 Errors in the coloring of the JMap. 

 The most southern hill of greenstone in East-Haven is omitted. 

 Also a small range of greenstone in the same town, on the east side of 

 Saltonstall's Pond. 

 Also an alluvial tract in the same town. 



In some copies the greenstone and old red sandstone in Sunderland, Deer- 

 field and Greenfield, have been made to exchange places. 



The western branch of the Mount Carmel ranoje of greenstone, which ex- 

 tends through Cheshire into Southington, is coloured as alluvion.
