1024 General Notes. 
The same mineral is an accessory constituent of a glaucophane rock 
from Japan. It has recently been described, by Haworth,! as occur- 
ring in a porphyrite from Missouri, and is also mentioned by 
Lacroix? as existing in the mica-schists of the Island of Groix, off 
the coast of France-—Emmonsite. Near Brixlegg, in the Unterinne- 
thal, is a mineral, occurring in little spherical groups of crystals 
implanted on barite. Its analysis gave 86.89 per cent. of SrCO,, 
and 13.14 per cent. of CaCO,, thus agreeing very closely with 
Thomson’s emmonsite from Massachusetts. Cathrein has measured 
the crystals, and found them to consist of rhombic prisms with 
a : b : c = .6090: 1: .7236.—Diamonds and Sapphires. A new 
discovery of diamonds and sapphires is reported* from Australia. 
he location where they have been found is Invere, New South 
Wales. They are found in a sand made up of quartz and tourma- 
line, and pieces of a rock composed of the same minerals,—Leucite. 
Prof. Judd* announces the discovery of leucite by Mr. T. W. E. 
David in a leucite-basalt from Byrock, N. S. Wales, Australia, 
about 450 miles N. W. from Sydney. Leucite, which until a few 
years ago was not known outside of Europe, is now known to occur 
in each one of the continents with the exception of Africa.—Cryp- 
tolite, the rare cerium phosphate, according to Mallard,° is nothing 
but monazite with a habit differing slightly from that which this 
mineral usually affects.— Gadolinite has been found, by Lacroix,’ in 
a cavity in the granitite of the Mourne Mountains, Ireland, and 
allanite has been discovered, by Levy and Lacroix,’ in a granite 
from Pont Paul, Finistére. 
CRYSTALLOGRAPHIC News.—In the course of an investigation 
of minerals from the Tyrol, Cathrein® detected in them several 
new planes. On a yellow-brown garnet, from Rothenkopf, 3 O08 
was found. This form is especially interesting, because it is not 
only new to garaet, but also to the entire regular system. The new 
triakistetrahedron— Iny EN occurs on tétrahedrite from Kogel, 
near Brixlegg; 32 P[, ,, P2 and 4 Ps on adularia from Schwar- 
zenstein; and p a diaspore Bt eia Y an elaborate
