lite calling it kaliophilite, the name having reference to its high 
percentage of potash. It occurs in colorless prismatic or acicular 
crystals, which do not, however, show sufficient distinctness of 
form to allow of the system being determined to which they 
belong. They show basal cleavage, are optically uniaxial with 
negative double refraction; the specific gravity is 2°602. An 
analysis afforded : ;

This corresponds to the formula, K,AI,Si,O, which is that of an 
anhydrous muscovite, and is analogous to that of anorthite, nephe- 
lite and eucryptite in which calcium, sodium and lithium, respec- 
tively, enter in the place of the potassium here present.— Min. petr.

Harstieire. Described by G. Flink of Stockholm. It occurs 
in prismatic orthorhombic crystals with an axial ratio of @:b6:c= 
0°7141:1:1°01495. No cleavage was observed; fracture small 
conchoidal to splintery; hardness 5°53; specific gravity 37049 ; 
colorless with vitreous luster. An analysis on 0°3 gram yielded:

This does not lead to a satisfactory formula, and the composition 
must remain somewhat doubtful until more material is obtained 
for investigation. Obtained at the Harstig mine at Pajsberg, 
Sweden.— Bihang Svensk. Vet.-Akad. Hand., xii, 1886. 
ScuuneiTE. A name given by A. von Inostranzeff to a form 
of amorphous carbon occurring in the crystalline schists of 
Schunga in the Olenetz government, Russia. A similar form of 
carbon from the Saxon Erzgebirge was called graphitoid by Sauer.

cHaRow. Vol. ix, pp. 273-365. St. Petersburg, 1886.—This part 
forms the closing portion of the ninth volume of the great work 
on Russian Mineralogy by von Kokscharow. It contains a sup- 
plementary notice of the interesting variety of xanthophyllite 
called waluewite, giving a more exact determination of the 
crystalline form than has been obtained hitherto; also an ex- 
tended review of papers on the topaz of Durango by N. von 
Kokscharow, Jr., and by DesCloizeaux, with an exhaustive list 
of calculated angles for the many new forms. A description 
is also given of the mineral Mursinsxirr, thus far known 
from two specimens only which were found more than thirty 
years ago. It occurs in minute crystals inclosed in large trans- 
parent topaz crystals from Alabaschka, near Mursinsk in the 
Ural. The form is that of a tetragonal pyramid with angles 
of 127° 31’ (terminal) and 77° 224’ (basal); two pyramids of 
the second series and several zirconoids were also observed. 
The color is wine- to honey-yellow, transparent to semi-transpar-
