PROF. BALY'S well-known work on “Spectroscopy,” which formed a single volume in the first edition of 1905, as well as in the second edition of 1912 and 1918, has now begun to grow so rapidly that the third edition is to appear in four volumes instead of the two volumes that were originally contemplated. This expansion is an almost inevitable sequel to the amazing growth of the subject since Bohr first introduced the quantum theory into spectroscopy in 1913; and no one will grudge the author more space in which to expound the wider knowledge that has been gained during the subsequent years. These topics, however, are not included in the present volume, which contains only one indexed reference to Bohr, and none to the quantum theory.
