Danaite.—A cobaltic variety = mispickel is found associated with 
iron and copper pyrites at Meadow Lake, Nevada Co., Cal. It is in dis- 
tinct, well formed, brilliant arjaiadé of a tin-white color, and mt a 
quarter of an inch in diameter. They are modified near] as in fig. 
Dana’s Mineralogy. This mineral gives cobalt reactions eta the biow 
pipe, and appears to contain a large percentage es = etal. The 
is said to contain nickel also, and is being mined fo ice 
innabar in calcite —Cinnabar of a eae faeinition color is found 
in Idaho abundantly spread i a gangue of massive compact lime- 
stone or marble. No quartz or other a are visible in the specimens. 
Wulfenite.—Molybdate of lea occurs in the argentiferous lead ores of 
the Empire mine, Inyo Co.,, . Itis in crusts and seams about one- 
eighth of an inch thick, and is pele ake with galena, cerusite, malachite, 
and chrysocolla. The contrast of the brilliant yellow color of this spe- 
.cies with the masses of green silicate is copper renders these specimens 
very beautiful and ee for cabine 
Sulphuret of silver—This m iecint 3 is s found i in ragged masses matted - 
with quartz shed ye associated with free gold, in the “Silver Sprout ” 
vein, —— District, Sierra Nevada.

It is in radiating prismatic crystals; color dark olive-green ; high spe- 
cific gravity, and before the blowpipe gives the reactions of tungstic acid 
and o manganese. 
pecular iron.—Mr. Bennett of Durango, Mexico, has sent me some 
interesting erystallizations of cb os iron ore, associated with oxyd of 
tin, from the tin washings of t 
Tetrahedrite, galena, cer fete ophwaseyhita blende, with a little red 
copper ore occur together in the Chicago claim, Shasta county, Cal. The 
ore is rich in silver.

cessor at the British Mu useum, was the only proper editor. He has added 
to this volume a full and elaborate index,—a great boon to botanists,— 
also the following brief Preface : 
“The present volume contains ce first portion of the works of the 
distinguished author, now for the first time collected in England, and re- 
printed from the originals, withou t change, i in accordance with his express 
desire. It had been his intention to reprint them himself with annota- 
_ tiens; but, unfortunately for a. this intention was never carried out, 
aad it remained for the editor simply to s superintyad verbatim reprint.
