new. Their axial ratio is .98123 : 1: 1.12679. The mineral is found 
in clefts of an andesite, or in the rock mass in the neighborhood of 
inclusions of quartz and augite 
In his ‘Notes on Some Misrni of the Fichtelgebirge, Sandberger” 
gives analyses of titanic iron sand from the banks of the Eger, of 
rhodonite from Arzberg, of the margarodite covering orthoclase erys- 
tals in the druses of the lithionite granite of Epprechtstein, of the 
chlorite pseudomorphs of orthoclase crystals in the dolomite of Streh- 
lenberg, and of a lithium mica from Fréstau, near Wunsiedel. The 
last named mineral is one of the constituents of a rock whose only 
other original Spa is white albite. Its analysis gave:

besides small amounts of TiO,, SnO,, FeO, CaO, CuO, As, Sb, Pb, Co, 
and B. The author thinks that there are certainly five distinct lith- 
ium micas known. 
Katzer™ mentions the occurrence of arsenopyrite and quartz crystals 
at Petrowitz, in Bohemia, of sphalerite and other sulphides, and of 
siderite at Heraletz, of wollastonite in fibrous masses on the contact of 
limestone with granite-gneiss, and of crystals of blue cordierite at 
Humpoletz, of andalusite at Cejod, of a caleiferous tourmaline at 
Benitz, and of gypsum crystals at seyeral localities in the same King- 
dom. The tourmaline analyses gave:

Crystals of epsomite are described by Milch” from Stassfurt-Leo- 
- poldshall, Germany. They are implanted on a granular halite or a 
saliferous clay, and reach in many cases several centimeters in dimen- 
sions. They are all columnar in habit, and are remarkable for their 
richness in planes and for the marked character of their hemihedrism. 
The principal forms occurring in them are © PX, o PS, œ P, o PS, 
æ PZ, PX, and 2P”. 
Several mad; twinned crystals of alabandite from a deposit of the 
mineral in the Lucky Cuss Mine, Tombstone, Arizona, have been anal-
