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 Gites: in 
thin folie. 
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 JSrom 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 hardnexs, this last mineral. 
Calstron-baryte. 
e have lately examined new specimens of this mineral, with 
$. So various in regard to the carbonates present, as to lead 
me to consider it a mechanical mixture of heavy spar, strontianite 
Calcite, and therefore not entitled to be considered as a mine- 
ralogical species.
