POPULAR SCIENCE REVIEW. 
The Science of Building , by E. W. Tarn, M.A. London : Lockwood. — 
The author has attempted to introduce the student of architecture to a 
general outline of the scientific subjects connected with his profession. The 
author has avoided abstruse calculation, and thus has rendered his book in- 
telligible to those students whose acquaintance with algebra and Euclid is 
of a limited character. Numerous woodcuts are scattered through the volume, 
which we think a good introduction to the science. 
The Use and Limit of the Imagination in Science , by John Tyndall, LL.JD., 
F.R.S. London : Longmans, 1870. — This is one of the author’s brilliant 
discourses on a most difficult subject. It is already familiar to most of our 
readers, so that we need say no more about it, save that in this edition the 
author has collected together and gives a series of critiques of different 
papers pro and con, which are really interesting reading. 
A Monograph of the Alcedmidce, or Family of Kingfishers , by R. B. Sharpe, 
E.L.S. London : Published by the Author, 1871. — This work has occupied 
the author from the year 1866 till the present time. It is now completed, 
and with 121 coloured plates forms the finest work of the kind in existence. 
Those who are interested in this wonderful group should consult Mr. Sharpe’s 
inestimable work.
