Abstract
THIS new “Bulletin” is comprehensive and in expensive. The authors are J. B. Macelwane, H. 0. Wood, H. F. Reid, J. A. Anderson and P. Byerly, all of whom have made distinguished contributions to seismology. They discuss the various theories of the origin of earthquakes, field data, the design of seismographs, the theory of wave propagation, and the interpretation of the results. References are abundant up to 1931, and there are a few for 1932; and the authors have evidently read and understood what they quote. Two omissions are perhaps worthy of notice. The work of Stoneley and Tillotson on surface waves is mentioned without statement of the results they derive for the thicknesses of the layers; and attention might have been paid to the theoretical solution for a sudden disturbance spreading in three dimensions from a small region.
