formidable.

prominent place belongs to Protopsalis tigrinus , belonging pro-

A Complete Course of Problems in Practical Plane Geometry , 
with an Introduction to Elementary Solid Geometry. New 
Edition, Revised and Enlarged. By John William Pal- 
liser. London : Simpkin and Marshall. 
The author, after pointing out the importance of geometry for 
art-students and artizans of every kind, tells us that in his prac- 
tical experience as a teacher — in connexion, more especially, 
with the Leeds School of Art and Science, and with the Science 
and Art Classes of the Leeds Young Men’s Christian Associa- 
tion — he has been unable to meet with a text-book at once suffi- 
ciently cheap and comprehensive for his students. He found 
that both teachers and pupils were obliged to obtain and consult 
a number of works on geometry in order to prepare for the 
examinations of the Science and Art Department. To do away 
with the consequent expenditure of time and money he has issued 
the work before us. Now although we do not believe in examina- 
tions, and consider that preparing for these performances is a 
radically false starting-point in any science whatsoever, we con- 
sider that the manual before us is likely to be very useful. It is 
characterised by clearness, simplicity, and a sound arrangement, 
and will, we think, fully meet the exigencies of the case.
