An analysis of the anthophyllite by Dr. Baskerville is 
given below, together with the results obtained by Prof. 
Penfield.*

The two analyses are very similar, and confirm Prof. 
Penfield’s conclusion that the specimen described by him 
was from the Bakersville locality. 
One specimen of a true anthophyllite was found at 
Corundum Hill by Prof. Penheld; but this was more 
fibrous and not of such good quality as that from the 
Bakersville locality. 
ENSTATITE. 
The enstatite from Corundum Hill that is commonly 
called anthophyllite, occurs as a rock composed of a mass 
of interlocking bladed grayish crystals of the mineral. 
The rock is very tough and tenacious and forms a per- 
fectly continuous mass with the dunite. The outcrop of 
the dunite at Corundum Hill is very similar to that near 
Bakersville. The hill of nearly ten acres in extent ha 
the dunite exposed over nearly its entire surface, and the 
enstatite is found at the lower south end of the outcrop 
in the zone of alteration products developed near the 
contact of the dunite with the hornblende gneiss.
