    This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1918 Excerpt: ...pole-effect having been developed, it is of interest to examine the wave-lengths of lines in the adopted list of international secondary standards known to exhibit pole-effect. In Table VIII, the first column gives the value published by the International Committee, the second shows the fundamental value obtained under these conditions, and the third contains the differences. The Mount Wilson values are not final, but represent our best knowledge of these lines at present. Definitive wave-lengths covering a wide range of spectrum will appear in a later paper. The mean difference shown in Table VIII is practically coincident with the mean difference obtained above in Table II, although the observations involved in the two cases are entirely independent. TABLE VIII In Table IX we compare our values with the determinations by Burns, Meggers, and Merrill1 for lines of group d. The mean indicated makes it clear that pole-effect played a part in their investigation, and that its amount was substantially the same as that existing in the international secondary standards. This latter fact is sufficient to account for the failure of these observers to find evidence of it in their results, as they made no comparisons with a source free from this influence. They say in their paper: " 1 Scientific Papers of Bureau of Standards, No. 274, 1916. 2 Ibid. "Thus it seems probable that the measurement of additional lines on the plates from which the I.A. standards were obtained would lead to the same values of the wave-lengths as though the plates had been taken under normal conditions." This conclusion is confirmed by the observations presented above, but it must be sharply distinguished from the statement in the summary at the end of their paper to the effect.
