THE GUARDIAN.—* Mr. Gregory’s stories are gathered from a wide field, and he is equally at home in recounting 
the latest triumphs of medical research and the wonders of astronomy. Through each chapter runs a definite thread of 
exposition of scientific methods and ideals on which the stories are strung.”

A Manual of Practical Physics. % 3% BApley. ps: 
School of Scienee, Kidderminster. LIllustrated. Globe 8vo. 3s. 
SCIENCE PROGRESS.—‘* This is just a collection of some 160 recipes for performing experiments in physics up 
to intermediate pass standard. Very excellent recipes they are too; the author's reputation as a writer of elementary 
text-books is a sufficient guarantee of that, and the book can be strongly recommended to the notice of school teachers 
who have large classes, so that several different experiments have to be supervised at the same time.”

Elementary Dynamics of the Particle and 
Rigid Body. By R. J. A. BARNARD, M.A., Professor of Mathematics, Royal Military College of 
Australia. Crown 8vo. 6s. 
THE TIMES EDUCATIONAL SUPPLEMENT.—‘ A work on dynamical principles which will prove of real 
assistance to beginners. Mr. Barnard has been a little daring, but we believe quite sound, in bringing rigid dynamics 
into this book. It has long been the practice to make Rigid a late subject, but here it is rightly connected up with the 
elementary dynamics of the particle.”
