J. Lawrence Smith on Emery. 355 
Prior to 1846, the existence of emery was rot remarked in 
Asia Minor or any of the contiguous islands except that of Samos, 
which fact is alluded to in Tournefort’s travels in the seventeenth 
century. In the latter part of 1846, I arrived in Smyrma, and 
was shown specimens which I recognized as emery: that came 
from a place about twenty miles north of Smyrna; they had 
been first discovered through the agency of a knife grinder of the 
ish government as well as to the arts emery being at that time ~ 
posed locality of this mineral. On this second visit other local- 
ities were made know to me that an English merchant by the 
name of Healy had succeeded in bringing to light.

The first locality towards which I directed my examination — 
was that of Gumuch-dagh, a mountain about twelve miles east 
of the ruins of Ephesus. Before, however, arriving there, ‘I 
discovered this mineral imbedded in a calcareous rock in a-valley: 
twenty miles south of: Smyrna, called Allahman-Bourgs.; the — 
Position not being very favorable for the ‘study of the geology of — 
this substance, my route. was continued to the place originally 
‘Bixed upon. Obtaining guides at the village of Gumuch, | com- 
Menced the.examination of the mountain, which is composed of 
bluish. marble resting on mica slate and gneiss. On-the very 
summit of the mouutain, the emery was found. scattered about 
and projecting above the surface of the soil. After examining 
the extent of the formation and satisfying myself that it was there 
M. Smith and some of the officers of the imperial powder works, 
to examine thoroughly into the importance of this mine, a bd 
cording to the report that will be made the government will de- 
cide on the steps to be taken with reference to it, &c. 
This circumstance, unimportant in itself, has subsequently be- 
come of great value to secure to me the priority of the discovery 
and examination of emery in situ in Asia Minor ;* and also to 
show that I have been instrumental in the development which has
