Mineralogy and chemistry: original researches by Prof. J. Lawrence Smith.

Excerpt from Mineralogy and Original ResearchesOf all the mineral substances employed in the arts few have offered so little opportunity for geological examination as emery, and consequently our knowledge of it in this particular is very limited.Aware of the importance of the study of this substance in site, both in a scientific and practical point of view, I did not lose the Opportunity afforded by my late position under the Turkish Government to develop certain facts that came under my notice the latter part of the year 1846. Prior to that period emery (which term is here used, as in the arts, to ex press that mixed granular corundum employed for abrasion), although known to exist in many places in greater or less abundance, was supplied to the arts almost entirely from the island of Naxos in the Grecian Archipelago. So true is this that the proprietors of the mines in that island controlled completely the price of this mineral. The emery from N axos frequently went under the name of Smyrna emery, from the fact of its coming to us from that port, where it is originally carried from the island for future exportation.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
