had been found here; also yellow pulverulent chap. 
oxide of antimony, and white pulverulent oxide of ' 
arsenic ; lying, in both instances, among crystals 
of their sulphurets. All the semi-metals met with Analysis 
of its Ores. 
at Nagyag, when carefully analyzed, are found to 
contain minute portions of gold. The author, 
by the simple process of cupellation, after the 
easy manner he has described ', has detected 
gold in all the specimens he brought from this 
mine. But the richer ores, consisting princi- 
pally of tellurium, contain, in a hundred iveight of 
the ore, from ninety to three hundred and forty 
German ounces of silver; and each mark of silver 
yields twelve or thirteen ounces of gold, or two 
parts gold and one part silver^. But all the ores 
do not contain silver, although all of them 
(1) This method oi cupellation was invented by FT. H. fVollaslon, 
Esq. M. D. Setretary to the Royal Society : it is tlie easiest and most 
expeditious mode of adapting the hlow-pipe to the developement of 
gold, silver, copper, &c. from their ores. 
(2) The ounce of the German miners, according to Raspe, (See 
Pre/, to Bom's Letters, p. 39.) is equal to one half-ounce English. 
The following table of weights was given to us by Mr. Gayo, the 
Director of the Laboratory at Cremnitz : 
One quintal (centenarius) = 100 pounds. 
One pound . . . . = 2 marks. 
Oim mark . . . . = 18 ioths. 
One fo<A is generally divided into four portions ; each of which is im- 
properly called, in German, a quintate, as distinguished from quintal i 
and the quintale consists of four deniers.
