POPULAR SCIENCE REVIEW. 
the least doubt, the first of its kind, and splendidly done. The author 
has been at pains to produce a work which will be really a compound 
not before brought out, and he has, in our opinion, succeeded thoroughly. 
He has attempted to produce a work which will not only make the student 
familiar with the abstract science, but with the everyday application of it. 
This a reader of the former works for students could not obtain, and he 
found that when he came to read a book like that of Culley, he was unable 
to understand it. By the assistance of this excellent manual he can now 
grasp both the science of the professor’s lecture-room and that of the prac- 
tical worker of the telegraph. 
Mr. G. F. Rodwell’s little book * is a very poor effort to teach students 
Natural Philosophy. In about 150 pages of duodecimo size the author deals 
with Statics, Dynamics, Hydraulics, Hydrostatics, Pneumatics, Light, Heat, 
Magnetism, and Electricity. If these are the lectures delivered at Guy’s 
Hospital, we recommend the author to enlarge them very considerably for 
the future. 
GOSPEL HISTOKY.t 
A SSUEEDLY those who have doubts as to the foundation of many parts 
of the Christian JReligion should obtain this remarkably clever book 
and study it. It is by the author of a work of great importance, and, like 
its predecessor, it displays a knowledge of Biblical events and Church 
history which seems quite marvellous. This is not the place, to be sure, 
in which we could review this volume ; but we commend it to the serious 
consideration of educated people. They will find it a calm and learned 
disquisition on the subject of Gospel Histoiy, and of the period at which 
the New Testament was first printed. 
A GOSSIP ABOUT SCIENCE^ 
T hese essays will appeal to those who have read the author’s former 
series. They are both terse and pleasant in point of style, and in- 
teresting in their scientific aspect, while at the same time they are per- 
fectly intelligible to any person of ordinary education. Among several 
papers of interest in the present volume, two are worthy of special merit; 
the one is a sketch of the life of Mary Somerville, and the other is upon 
the coming transit of Venus. The latter is an important paper, and in it 
Mr. Proctor makes an appeal to the Government to be more generous in
