672 SCIENTIFIC RECORD FOR 1883. 



cleavage fragments, and associated with them feldspar, quartz, gothite, 



and fluorite. The largest topaz fragment weighed 1 1 h ounces ; the largest 

 crystal weighed. 4 ounces, and was of a light straw color, perfectly trans- 

 parent, and free from flaws. The crystals are highly modified. 



A new locality for cassiterite has been described by W. P. Blake 

 (Amer. Jour. Sci., xxvi, 235) near Harney, in the Black Hills, Dakota. 

 It occurs in a coarsely crystalline granite, together with spodumene, in 

 gigantic crystals 2 to G feet in length. The tin ore is also found in 

 stream deposits in the same region. Cassiterite is also reported from 

 Rockbridge County, Virginia, King's Mountain, North Carolina, and near 

 Ashland, Clay County, Alabama. Professor Blake also describes a new 

 locality of green turquoise or chalchuite (from the Mexican chalchihuitl) in 

 Cochise County, Arizona. This locality is about 20 miles from Tomb- 

 stone, on a spur of the Dragoon Mountains, in what is called Turquoise 

 district. It is interesting to note that, like the Los Cerillos locality, 

 there are ancient excavations which were worked a long time since. 

 The color of the mineral is a light apple-green or pea-green, and it is 

 less abundant than at the New Mexico locality. 



Professor Harrington, of Montreal, has given (Trans. Roy. *SV>c. Can- 

 ada, May 2, 18S3) a description of the occurrence, with analyses, of some 

 interesting minerals new to Cauada, viz, meneghinite, from near Marble 

 Lake, township of Barrie, Ontario; tennantite, from the Crown mine, 

 Capelton, Quebec; strontianite, from Saint Helen's Island, near Mon- 

 treal, and acmite, as a constituent of the nepheline syenites of Montreal 

 and Belceil. 



Of new foreign localities little need be said here. The magnificent 

 stibnites recently brought from Japan, however, must be mentioned 

 (see Amer. Jour. #ci, xxvi, 214). The locality is on the island of Shik- 

 oku, in Southern Japan. The antimony mines at this place have been 

 long worked, and the Japanese have long prized as ornaments the fine 

 group of crystals they have yielded. It is stated that they mount them 

 in flowerpots to adorn their dwellings. The crystals which have come 

 to this country are not only by far the finest known specimens of the 

 species, but they outrank in size and beauty the crystals, of all other 

 metallic minerals. The crystals are of splendid luster, often very highly 

 modified crystallographically, and of remarkable size. Crystals in the 

 Yale Museum, for example, have been described which have a slender, 

 spear-like form and are nearly 2 feet long. There are also large groups 

 with diverging crystals 3 or 6 inches in length. 



NEW MINERALS. 



Bertrandite. — This mineral was briefly announced by M. Bertrand 

 several years since (Bull. Soc. Min., in, 9G); and now its characters 

 having been fully made out, it has been named after him by his col- 

 league, M. Dainour. It occurs in minute crystals attaining a maximum 

 length of three or four millimeters. These crystals belong to the ortlio-
