Translation of a paper read to Amer. Phil. Soc. Aug. 21, 1874. 

 Describes occurrences of native tellurium, tetradymite, altaite, hessite, 

 petzite, sylvanite, calaverite, and bismuth-glance. Also describes as 

 new species a tellurate of copper and lead, and a sulphide of bismuth, 

 silver, and lead ; the latter is named Schirmerlte, after Director Schirmer, 

 of Denver, and contains PbS . 2Ag2S . 2Bi^S3. A postscript throws doubt 

 on the two species described by Endlich as Schirmerite and Henryite. 

 Maintains that Endlich's Schinnerite is only an impure Petzite.
