ferved a fpherical pyrites that was coppery. In the 

 ifland Staritzo, a like fort, of the fize of oranges 

 and lemons-f , is found. 



To illuflrate the figures of the pyrites, in vary- 

 ing which nature takes a peculiar pleafure, it may 

 be proper to confider thofe of other ores. Gold-ore, 

 as fuch, is a rare thing, confequently it is difficult 

 to afcertain any peculiar figure of it-, the gold that 

 is found in certain fands, clays, and other earths, in 

 Mints and (tones, being rather in a native than ore 

 fbate, as in fpangles, foils, and grains. Silver-ores, as 

 the glajfy and red-goldifh fort, have their peculiar 

 figures j though the latter more than the former, fre- 

 quently exhibiting ten or twelve fides,but they are 

 ofteneft found prifmatical, like long angular Haves 

 or bars, yet of unequal fides, and like mountain- 

 cryflal, terminating in four or five unequal- fhaped 

 ends. 'Tis remarkable of glajfy ore, that it is generally 

 found of a cubical form, and regular enough ; a 

 circumftance never to be affirmed either of red- 

 goldijh, or any other ore, if you except lead-glitter 

 or galena , and a kind of Swedifh iron-ftone of the 

 nature of glitter. The white goldifh ore may be 

 deemed a copper, rather than a filver ore \ and fo 

 indeed may the other two, from their yielding 

 large quantities of copper. Iron-ore, or, as it is 

 called, iron-ftone (to diflinguifh it from iron-py- 

 ites) generally confifts in fhoads or fragments, in 

 fquats or flat veins, exhibiting no peculiar figure, 

 if we except that called the glafs-head^ or blood- 

 y?0/Z£,diftinguiihable partly by its fpherical, partly by 

 its hemifpherical figure, and its brown-red, or rufTet 

 hue, and thence denominated botrites blood- (lone. 

 Now as no other metal befides iron, is, in its ore- 

 date, of a round figure, except that of iron-pyri-
