“Contains much historical and scientific matter reduced to a pleasant and 
readable form. Of the volume as a whole, we can only speak in terms of the 
highest praise, and we regard it as a work which deserves a place on the 
shelves of every student of physical science.”—4 xaminer. 
** A work of high value both to the student and to the tourist on the shores 
of the Bay of Naples.”"—Pall Mall Gazette, 
“This is an attractive book for those who have no enthusiasm for ‘Alpine 
Plants.’ Its pure style, the interesting excursion details, and the beautiful 
descriptions of scenery, make it a winning book to general readers.”—Xecord.

CHEMISTRY FOR STUDENTS. By 
A. W. WILLIAMSON, Phil. Doc., Professor of Chemistry, University 
College, London. Extra feap. 8vo. Cloth. Price 8s. 62. 
“ This volume is really a too rare example of what a good elementary text- 
book in any science ought to be: the language, brief, simple, exact; the 
arrangement logical, developing in lucid order principles from facts, and 
keeping theory always dependent upon observation ; a book that keeps the 
reason of the student active while he strives to master details difficult but never 
without interest, and that furnishes him with means for practising himself 
in the right management of each new tool of knowledge that is given to him 
for his use." —Z.raminer.

AN ELEMENTARY TREATISE ON 
HEAT, with numerous Woodcuts and Diagrams. By BALFOUR 
STEWART, LL.D., F.R.S., Director of the Observatory at Kew. 
“This compact little treatise is commendable both as an elementary expo- 
sition of the chief phenomena of heat and their practical applications, and 
also as a brief exposition of the philosophical theories which have recently 
given a new interest tothe phenomena. The structure of the work is also 
excellent.” —Fortuightly Review.

DESCRIPTIVE ASTRONOMY. A Hand- 
book for the General Reader, and also for practical Observatory work. With 
224 Illustrations and numerous Tables. By G, F. CHAMBERS, F.R.A.S., 
Barrister-at-law. 
The aim of this work, briefly expressed, is general usefulness, whether in 
the hands of the student, the general reader, or the professional observer. 
Great pains have been taken to present the latest information on all branches 
of the science. The development of Astronomy is now so rapid that’ unless 
an author exercises constant vigilance his book must fall behindhand : and it 
is believed that this volume not only contains the most recent discoveries and 
deductions, but that in it will also be tound information hitherto to be met 
with only in the publications of learned societies, difficult of accessand incon- 
venient for reference even to the Astronomer, and absolutely out of the reach 
of the general reader.
