3. New locality of £ Tuor spar.—This interesting ini 
which Patrin,* a French mineralogical traveller salts me 
years ago had not been found on the Western ContlnaGt 
appears, on the contrary, to be of frequent occurrence. We 
have already announced several new eee: in the 
present number, and we now add another. 
Fluor spar occurs at Putney,t Venmude and was discov- 
ered by the Rev. Elisha D. Andrews of that place. His let- 
ter to the Editor states that it occupies the fissures in ledges 
of slate that the principal vein is six or eight inches wide 
and that after being followed four feet it decreased to one or 
two inches and had every appearance of running out. 
Geological and Mineralogical Notice.—From specimens 
transmitted by Mr. Andrews we are enabled to state that the 
rock in which this fluor spar occurs is a primitive slate 
which appears to be a mica slate, just passing into a clay 
: the Tortusely and lustre of the mica are still discerni- 
ble ile it has lost its elegance. In primitive slaty regions, 
rocks of this middle character are of frequent occurrence, 
but we do not remember that fluor spar has ever been found 
in them or in any slaty rocks before. 
This fluor spar isofa grass or emerald green with here and 
there a tinge of purple ; but green is almost the sole colour 
and in this respect it is remarkable this being rather a rare 
colour of fluor spar and not found, we believe in ‘es coun 
try, except near Northampton by Dr. David Hun 
he Putney fluor is not ecrystalized, although ie has the 
usual crystaline structure and exhibits on its surfaces an evi- 
dent tendency towards crystalization. Its phosphorescence 
is very lively and agreeable; ona hot shovel ina dark place 
itexhibits violet light sey other shades; some pieces 
emit nearly pure white light; large pieces easily become 
luminous and remain distinctly visible after being brought
