-R.S., Professor _ Chemistry in Owens College, Manchester. London, 
Macmillan & Co., 1866. 18mo, pp. viii, 398. —This book of Dr. Ros- 
coe’s, though dosaietly an elementary work, is written from an advanced 
standpoint, and, while simple and clear in its statements, it carries the 
student fully up to the position which the science of chemistry has now 
reached. Ado opting the unitary system in its completeness, it spends but 
little time in prefatory explanations, but bi the philosophy to be 
gathered from the several substances consi e notice several 
chapters of great value: especially those on the ‘intel a a of 
gases; on the atomicity of the elements; on crystallography; on spec- 
trum analysis, and solar and stellar chemistry ; and his chapters intro-
