FA. Genth—Contributions to Mineralogy. 307 
As new localities of tetradymite I mention the Phoenix 
mine and Boger mine, Cabarrus Co., 
Several localities at which tetradymite was found, were 
ven by Prof. C. U. Shepard, one in the Chestatee river near 
Dahlonega, Lumpkin Co., Ga., then the Pascoe mine, Cherokee 
Co., and another near Van Wort in Polk Co., Ga. (this Journ, 
[IL], XXvii, 39). 
The discovery of bornite at Field’s gold mine, near Dahlo- 
nega, Ga., was announced by Dr. Jackson (11), xxvii, 366). 
This I proved subsequently to be erroneous (Mining Magazine, 
Vad , i, 358), showing the mineral, like that from Fluvanna Co., 
a., to be tertellurid of bismuth, which opinion was fully 
corroborated by a reéxamination of the same mineral by Mr. 
David M. Balch, (this Journ, [II], xxxv, 99). 
These are, as far as I can ascertain, all ‘the localities at which 
tellurium minerals have been found in the Atlantic States, 
and they represent only the one _Species, tetradymite, but in 
its two well established varieties.* 
The Pacific States have lately furnished a far greater variety 
and in fact, with the exception of sylvanite, all the known tel- 
urium minerals have been found there, together with several 
new ones 
Prof, W. P. Blake was the first who reported the occurrence 
of tellurium ores in California (Geological Reconnoissance in 
California, 302) (this Journ, [II], xxii, 270), stating that a 
mineral containing tellurium and silver, probably hessite, had 
been oat S out from a gold drift near Georgetown, Eldorado 
uri is contained in a A a on ng “New Me- 
lones Gold and Silver Mines,” in which appears a Report of 
Mr. —— A. Stetefeldt on the Reduction of "Telluric Gold 
recognizable by its tin-white color we great luster.” 
Mr. Guido Kiistel describes in the Mining and Scientific 
Press of San Francisco, of May 20th, 1865, the principal ore 
of the Melones mine, << te Tlurite () of” silver-gold as a new spe- 
cies, gives its specific gravity as from 9 to 9°4 and the cdémpo-
