nomorphite. It occurs as an alteration product, forming a white 
coating about a nucleus consisting of rutile or menaccanite, or 
both. This wr Rare has in tin’ a radiated fibrous structure, but 
close relation between the mineral and titanite. An anal ysis by 
corresponds to the formula Ca 1 ‘0, Found in the amp shibolyte of 
the “Hohe Eule,” Silesia. It is “regarded by Lasaulx as probably 
— with the white a product from cisaseheans 
rutile often observed in microscopic sections of rocks but 
Gicherto of uncertain composition. 
Professor Lasaulx also describes a manganese vesuvianite (3°23 
p. ¢. MnO) from the neighborhood of J ordansmiihl, in Silesia, 
and gismondite from the basalt of Schlauroth, near Gérlitz, The 
crystals of gismondite are shown to be Dare ally twins, belong- 
ing to m3 triclinic system. —Zeitsch, Kryst., i 2.
