Abstract
DR. BOHR'S letter in NATURE of March 4, although giving an interesting discussion of some aspects of this problem, does not meet the particular point which my letter was designed to raise. This point was solely that since combination series must be expected from the “4686” series in any circumstances, and since the lines so calculated occupy the positions in which lines have been found by Evans, they cannot be used to discriminate between theories of the origin of spectra, for we cannot prove that the observed lines are not these combination lines. It is true that Bohr's theory involves the combination principle, but so also does that of Ritz, who originated the principle.
