Wire silver, a common variety, is a para- 

 morph of crystalline silver after amor- 

 phous silver, which has been forced 

 through small openings while soft.

 (II): 1. 



"Kustelite" 



["Amalgam," in part; "arquerite," "bor- 

 dosite," "kongsbergite;" included, along 

 with argentiferous mercury, in the spe- 



\ cies "amalgam" by Dana, but there is 

 no definite evidence that it is anything 

 but a variety of silver containing vari- 

 able amounts of isomorphous mercury. 

 Wire gold, a variety, is probably a para- 

 morph of crystalline gold after amor- 

 phous gold which has been forced 

 through small openings while soft, cor- 

 responding to wire silver. (See above.) 



"Electrum." Given a special name by 

 the ancients, though recognized by 

 them to be only an argentiferous vari- 

 ety of gold. 



Occurrence in nature reported by Schmitz, 

 Z. deut. geol. Ges., 4: 137. 1852. (Not 

 in Dana.) 

 "Rhodite." 

 "Porpezite." 



Occurrence in nature reported by Wohler,

 nik, Trav. Mus. Acad. Sci. Petro- 

 grad, 6: 49. 1912. (Not in Dana.) 



"Quicksilver." Liquid at ordinary tem- 

 peratures, but crystallizes at — 39°C. 



"Amalgam" in part. Included, along 

 with mercuriferous silver, in the spe- 

 cies "amalgam" by Dana, but there is 

 no definite evidence that it is anything 

 but a variety of mercury containing 

 variable amounts of silver, either in 

 solid, isomorphous form, or dissolved, 

 liquid form.
