a striking difference between what is called the white py- 
roxene of Kingsbridge and the common augite, as the 
Kingsbridge augite is as fusible as the scapolite of Bolton, 
which would rather induce us to place this variety of py- 
roxene with the scapolites which in many other respects it 
resembles, 
Before | conclude it may not be quite uninteresting to 
inform you that while on a visit to Chesterfield, Massachu- 
setts, [ had.an opportunity of seeing a fine specimen of the 
- siliceous oxyd of manganese, which was obtained in that 
nei urhood, but the precise locality | was unable to as- 
certain, owing to an inadvertence of my companion in hav- 
ing prematurely given an opinion of its value. I however 
obtained a few specimens from the mass which was shown 
me, which I shall describe as follows ; it is of a bright rose 
red colour, and translucid, particularly at the edges, with 
some lustre, structure rather granular, found in compact 
masses accompanied with the gray oxyd, hard, scratches 
glass, takes a fine polish and in this state constitutes a beau- 
tiful mineral which is rather rare, found only in Sweden 
in England, it isso exactly similar to specimens which 
Ihave from Devonshire that it is impossible to distinguish 
the difference. W. M.

Notice of Fluor Spar by Tuomas H. Were. 
“ Since writing you, I have had the pleasure of being able 
to trace out the new locality of Fluor.* It is situated in 
Cumberland, about one mile beyond Diamond Hill, on the 
direct toWrentham. Itis found at a number of differ- 
ent places. At one it is imbedded in a vein of quartz tra- 
versing a granitic or sienitic rock, and at another it is found 
with quartz loose in the ground. The colours of the speci- 
mens which I obtained are purple, blue of various shades, 
from pale to indigo, blue with a tinge of green, and white. 
hey all, (with the exception of the white,) appear of a 
beautiful purple when viewed by candle light.”
