166 §©Lieut. Baddeley on the geognosy, &c. 
chlorophane, the characters of which are given below. The 
rock it was associated with, has not been examined. 
Colour.—A lively light green, 
Translucency.—Deeply translucent on the edges. - 
Structure.—Laminar, sometimes indistinctly so, approaching 
compact 3; intimately associated with calcacrous 
spar. 
Lustre.—Dull, or none. 
Hardness -—About that of fluor. 
Powder.—Whitish green, and rough. 
Specific Gravity.—3. 0. 
Effect in Acid. —Throws out a few bubbles, cwing probably 
to the calcareous spar it is associated with ; when 
sulphuric acid is poured upon it, in a state of powder, 
it gives out white fumes which corrode glass. 
Phosphorescence.—Piaced on a heated poker it phosphoresces 
in a dark room with a beautiful green and purple 
colour. In boiling water it emits a palish light. 
This phosphorescence was observed after the mi- 
neral had been exposed to acid. 
Effect of the Blowpipe.—When exposed to its exterior flame 
it does not decrepitute, but phosphoresces with ‘ 
beautiful blue colour, like the interior flame of 
the blowpipe, and becomes white. When expo- 
sed to the interior flame it forms a white dull 
enamel,
