8. Hezbanyite, a supposed new mineral. — Frenzel has given the 

 named rezbanyite (previously use. I by Hermann m another sense) 

 for a new sulpho-liiMtmthite of lead, identified at Bezhunya, Hun- 

 gary. It is a light lead-may mineral of metallic luster and black 

 streak. Hardness 2-5-3, specific gravity 6-09-6-88. After deduct- 

 ing ft!4 per cent chalcop\ rite, 5 per cent calcite, an analysis gave 

 S 17-85, Bi 59-08, Pb 19'80, Ag 1'89, Cu 1*71, Zn tr. =100-33. 

 Tor this the formula 4 PbS + 5 Bi Q S 3 is calculated. Other analyses 

 give approximately similar results, but the variation is so great 

 that the composition must be considered still doubtful. The 

 mineral occurs massive intimately mixed with chalcopyrite and 

 calcite, also imbedded in ipiartz. — Min. I'etr. Mitt/e, 1882, p. 175. 



9. Banburit' /mm Switzerland. — A third locality has been 

 recently diseo\ ered for danl)urite, \ iz.. on iheScopi, in Graubiinden, 

 Switzerland. It is described by ('. Hint/.e as occurring in Iran- 

 parent crystals in habit resembling topaz, like that from Russell, 



obtained on the American mineral ; the observed planes are also 

 the same, with the addition of several new ones. The terminations 

 of the crystals differ from those of Russell in habit. In optical 

 relations the crystals of the two localities are nearly the same. 

 it is suggested that the undetermined mineral called hessenbergite 

 (Sy>t. Min., 5th ed., p. 762) may perhaps be identical with 

 danburite. — Z- its' ■hr. Kryst., vii. 



10. Wurtzite from Montana. — Mr. Richard Pearce has re- 

 cently discovered the rare mineral wurtzite at the "Original 

 Butte .Mine.*' Butte. Montana. It occurs in small crystals of the 

 characteristic hexagonal form, together with pyrite and zinc

 Macmillaii *S: Co. — A handsome and handy volume, one of the 

 fruits of the leisure of the aged ex-curato,- of the Royal Gardens, 

 Kew. mainly gathered from the MSS. of his son, the late Alex- 

 ander Smith, who was the curator of the Kew Museum—now so 

 extensive and interesting — from the time of its origination until 

 his health gave way, in 1858. Under the circomsta
