COMPACT GALENA OR LEAD-GLANCE. 869 The streak is shining, inclining to splendent. It is not so easily frangible as the preceding subspecies ; but agrees with it in the remaining characters. Constituent Parts. It is a compound of Sulphuret of Lead and Sulphurct Antimony, and a small portion of Silver. , Gcognostic Situation. It occurs in veins, and is usually accompanied with common galena or lead-glance. It is worthy of remark, that when the two subspecies occur together, the com pact always forms the sides of the vein, and this probably owing to its having been in a less perlect state of solu tion. It is also accompanied with black blende, common b'on-pyrites, copper-pyrites, quartz, and heavy-spar. Gcographic Situation.
