Abstract

THE literature of the theory of relativity and of the subjects allied to it is increasing so fast that it is becoming very difficult for any one to keep pace with it, but several of the books in the collection under review present their subject in so novel and interesting a manner as to be well worthy of the attention of the most seasoned student of relativity. Little need be said of the first book (1), for it consists merely of the French translations of the two chapters on the quantum theory of spectra and the theory of relativity issued as supplements to Dr. N. R. Campbell's well-known book on “Modern Electrical Theory.” It will be sufficient to state that the French translation expresses the meaning of the original text clearly and fully. It is well printed and commendably free from misprints the few that remain are fairly obvious and unlikely to mislead the reader-and will certainly prove helpful to those French students of experimental physics to whom the more mathematical text-books on relativity by Becquerel and Galbrun are a stumbling-block.
