in limonite. It is named after Rasp, the discoverer of the Broken 

 Hill mines. — Ann. Mus. Wien., xii, 1897. 



Leonite. A mineral closely related to blodite, obtained from 

 the Prussian salt mines of Westeregeln and Leopoldshall. It is 

 characterized by its containing potassium in place of sodium, its 

 formula being MgS0 4 . K 2 S0 4 + 4H 2 0. It occurs in monoclinic 

 crystals which are now described by C. A. Tenne, the existence 

 of the mineral having been earlier recognized. — Zs. Geol. Ges., 

 xlviii, 632. 



Tripuhtite. A new antimonate of iron from Tripuhy, Brazil, 

 described by E. Hussak and G. T. Prior. It occurs in microcrys- 

 talline aggregates of a dull greenish yellow color. The streak is 

 canary-yellow; the specific gravity 5*82. An analysis gave the 



following results : 













Sb 3 B FeO 



CaO

The above corresponds to the formula, 2FeO . Sb 2 6 . — Min. Mag., 

 xi, Dec, 1897. 



Gersbyite. A hydrous aluminum phosphate near lazulite in 

 composition, and resembling it in its fine blue or bluish green 

 color. It occurs in grains and small crystals imbedded in the 

 cyanite of a schistose damourite-quartzite. Five analyses give 

 amounts of water varying from 7 19 to 15-40 per cent. It is 

 named by Igelstrom from the village Gersby, near which it is 

 found in the Ransater parish, Wermland, Sweden. The same 

 region has afforded an imperfectly investigated mineral called by 

 Igelstrom Mtjnkrudite. It seems to be near svanbergite in com- 

 position. — Zeitschr. f. Kryst., xxviii, 310, 1897. 



Langbeinite. An anhydrous potassium-magnesium sulphate, 

 K 2 Mg 2 (S0 4 ) 3 , described by Luedecke from Westeregeln and other 

 points in the Prussian salt mines. It is remarkable as crystalliz- 

 ing in the tetartohedral class of the isometric system, the crys- 

 tals being highly modified and characteristic in form. The 

 specific gravity is 2*83. The iresh salt is colorless and without 

 taste. The analyses made agree closely with the above formula.

6. Handbuch der Mineralogie, von Dr. Carl Hintze. Erster 

 Band, 160 pp. Elemente, Sulfide, Oxyde, Haloide, Carbonate, 

 Sulfate, Borate, Phosphate, pp. 1-140. Leipzig (Veit & Comp. 

 1898). The appearance of the first part of Volume I of Hintze's 

 Mineralogy is encouraging, as showing that notwithstanding the 

 labor which the author has put upon the nearly two thousand 

 crowded pages of the second volume already completed, his 

 energy is not exhausted, and at no very distant date we may hope 

 to see the entire work completed. The present partis devoted to 

 the native elements, beginning with carbon and extending nearly 

 through the discussion of iron.
