copper, while part of the arsenic gives place to antimony.* Herr 

 Boricky describes, under the name of Zepharoviehite, a new* species 

 allied to Wavellite occurring in the sandstone of Trenic in Bohemia.! 

 Tschermak proposes the name of Simonyite for a salt lately found 

 at Hallstadt, closely related to Blcedite, from which it differs, how- 

 ever, in being stable when exposed to the air.J Finally, Dr. 

 Schrauf applies the name Simlaite to a mineral from Simla in 

 India, similar to meerschaum, but containing alumina, and belong- 

 ing to the group of halloysites.§ 



Two Cornish minerals have lately been analyzed by Professor 

 Church — the one a variety of kaolin, akin to lithomarge, and termed 

 Restormelite ; the other is the beautiful green mineral known as 

 chalcophyllite, or copper-mica. || The formula of restormelite may be 

 written Al a 3 . 2 Si0 2 + 2 aq. ; while the composition of the chalco- 

 phyllite may be thus expressed : 8 CuO . A1 2 3 . As 2 5 + 24 aq. 



Attention is directed by Mr. S. Gr. Perceval % to the occurrence 

 of topazes in the granite of Lundy Island, somewhat similar to the 

 well-known crystals from the granite of the Mourne mountains. 

 The writer of this Chronicle has for several years past been familiar 

 with specimens of both topaz and beryl from Lundy. 



Professor How follows up his ' Contributions to the Mineralogy 

 of Nova Scotia ' by further notices of the two species — natroboro- 

 calcite and silicoborocalcite, now better known under Dana's names 

 of TJlexite and Howlite.** Both minerals have been found good 

 substitutes for borax in welding. 



We learn from the ' Levant Herald ' that a large meteorite fell 

 at Mourzouk, in Fezzan, on or about the 25th December, 1869. 

 The fall occasioned considerable consternation to a group of Arabs 

 who were standing near, and they immediately discharged their 

 muskets on the unwelcome stranger.tt 



It seems likely that the Australian mineral lately introduced 

 under the name of Wollongongite will in future be known by some 

 more appropriate designation. The Kev. W. B. Clarke has pointed 

 out that some little error has arisen in assigning to this species a 

 local habitation and a name. In fact, the so-called Wollongongite 

 occurs not in Illawarra, but at a place called Petrolia, formerly 

 known as Beedy Creek, where it was recognized by Count StrzelecM 

 as far back as 1839. Under these circumstances the name ceases 

 to be appropriate, so that " there can be no question, I think," says 

 Mr. Clarke, " that Wollongongite is a misnomer, and that Professor 

 Silliman will change it." 



A good deal of common sense characterizes the little minera-
