There are a few more minerals described which seem to require 
a thorough examination in order to establish their claim to be called 
new, as for instance Skugisan and JMonophan belonging to the 
family of the zeolites and noticed by Breithaupt. 
The Mengite from Siberia, and the Monticellite from Vesuvius 
and noticed by Brooke and Berzelius from Galloro near Rome, a 
kind of anhydrous zeolite which is difficult to fuse and becomes. 
gelatinous with muriatic acid; it is noticed by Necker De Saussure.

10. Ozokerite, a new combustible mineral.—This mineral occurs 
at Slauik Moldavian District near the Karparthes and has been call- 
ed by Glooker, Ozokerite (o%:/v to smell, xngos wax,) it is of a talcose 
structure, the color between green and brown, of the’ spec. grav., 
0°955 to 0-970, it may be kneaded between the fingers, melts into 
a clear mass in the flame of a candle, is soluble neither in alcohol nor 
water, even when boiling, and but slowly so in ether and spirits of 
turpentine. 
This mineral may serve as an excellent material for lamps or ta- 
pers burning like wax with soft clear flame and diffusing on its being
