ORIGINS OF CLERK MAXWELL'S ELECTRIC IDEAS, as described in familiar letters to William Thomson, edited by Sir Joseph Larmor. 56 pages, illustrations, 18 )< 26 cms. Cambridge, The University Press, 1937. Price $I.OO. The letters printed in this book have emerged among Lord Kelvin's manuscript remains. They cover the period February 20, 1854 ' to September I, 1879, and are addressed to Maxwell's scientific friend William Thomson. In them there is given an account of the genesis and rapid progress of Clerk Maxwell's ideas as he groped toward a structural theory of the electric and magnetic field. The letters were originally issued as Part V of the Volume 32 of the proceedings of the Cambridge Philosophical Society. Because they may interest a larger circle they are made available in the form of this book. R. H. OPPERMANN.
