366 Euclase in Connectiait 



From Schwarzenberg, Saxony, 4,718, Breithaupt. 

 From Arendal, Norway, 4.721, do. 



From Fredericksvairn, Norway, 4.735, do. 



Ilmenite. 



Fromllmen, . . G. =4.766 4.808, G. Rose. 



Do. do. . . 4.805, Breithaupt. 



Washingtonite. 

 From Westerly, R. I., . . G. =4.963, Sheparb. 



From Litchfield, Conn., . . . 5.016, do. 



Concerning the comparative hardness of these minerals, I can 

 only state at present that the Washingtonite is harder than the 

 Axotomous iron-ore. 



The beautiful crystals from Amity and Monroe, Orange county, 

 N. Y., belong to the species Axotomous iron-ore. The Washing- 

 tonite is also found at Goshen, Mass. along with spodumene, in 

 thin folise. 



Euclase in Connecticut. 



This rare mineral is found in its gangue (for the first time ever 

 observed) at the topaz and fluor vein of Mr. Lane at Trumbull. 

 It occurs in thin, transparent, yellowish-white tabular crystals, 

 lining cavities in a silvery white mica, and sometimes imbedded 

 in a dark purple fluor. 



Supposed Phenakite from Goshen ^ Mass. 



A new examination of the specific gravity of this mineral* 

 satisfies me that it is not Phenakite. Its gravity=2.75 . . . 2.76, 

 which is too low for Phenakite, and slightly superior to Beryl. 

 It also slightly exceeds in hardness, this last mineral. 



Calstron-haryte. 



I have lately examined new specimens of this mineral, with 

 results so various in regard to the carbonates present, as to lead 

 me to consider it a mechanical mixture of heavy spar, strontianite 

 and calcite, and therefore not entitled to be considered as a mine- 

 ralogical species. 



New Haven, July 25, 1842.
