Lehrbuch der Krystallkunde oder Anfangsgriinde der Krystallo- 
graphie, Krystallophysik, und Krystallochemie, von C. F. RAMMELS- 
BERG, Dr. und Professor an der Universitat zu Berlin, ete. 236 pp. 8vo, 
with 250 wood-cuts.--This work is a Text-book of elementary Crys- 
lallography, in which the subject is presented with clearness, and well 
illustrated with figures. The Chapter on Isomorphism and other points 
in chemical crystallography, give special value to the work.

On Osteolite, a new mineral near Apatite; by C. Bromers, (Ann. 
Ch. Pharm., Ixxix, 1; in Ausz. Pharm. Centr., 1851, $01; here from 
eb. u. Kopp’s Jahresb. f. 1851, p. 813.)—Osteolite is externally a

chalky or clay-like mineral, not becoming plastic in water. Within, it 
is

Also a trace of chlorine in No. 1. The mineral contains therefore 86 
P. ¢. of phosphate of lime (Ca? B), but fails in the fluorid and chlorid 
Which characterizes apatite. It is a product proceeding from the alter- 
ation of dolerite.

A. Scacchi distinguishes two types of crystals, represented in figures 
and 2 (copied with a different lettering).
