The classification adopted by Tschermak is much more simple, 
being as follows: 
I. METEORIC STONES. 
. Eukrite—Anorthite and augite, iron being rare. 
a bronzite, enstatite; iron rarely seen, 
3. Chondrite—Olivine and bronzite with iron. 
Il. METEORIC IRON. 
4. Mesosiderite. miilicates and meteoric iron forminga granular mixture. 
5. Pallasite—Meteoric iron porphyritically enclosing crystals of silicates. 
6. Meteoric iron. 
GeELatinous Sitica.—Dr. H. Leffmann has found that at the 
bottom of bottles containing certain siliceous geyser waters from 
the Yellowstone National park, there is deposited a quantity of 
gelatinous matter looking like the white of egg, which, on n analy- 
sis, proved to be nearly pure silica. It was piei structureless, 
and by heat dried to a white opaque mass. After having 
closed for several weeks in a closed rere with strong sulphuric 
acid, it shrank to about one-tenth its vo 
The water from the ‘ ‘Opal spring” is ope t, appearing ’ 
what is produced by adding an alcoholic scat of rosin to 4 
large volume of water. The opalescence remains for m | 
oo silica not being deposited unless the ane is evapy” : 
ZEOLITES FROM FRITZ IsLanp.—B. Sadtler, Jr., has analyzed the 
chabazite, mesolite and apophyllite from Fritz island, nC 
ing, Pa. The analyses are published in the Am 
Fournal, and they agree closely with analyses of he same miner 
als from other localities. 
Native LEAD From Ipano.—Professor W. P. Blake has co 
native lead and minium near Bellevue, Idaho, where they — 
galena. The native lead, a rare species, “ is in small rounded masses ie 
or grains from an eighth to one-quarter of an inch in din ; 
sometimes in irregularly reniform bunches, weighing an reer the 
more. The red oxide is in the form of coatings or ir Ons 
metal.”—Amer. Four. Science. :
