Accurate wave lengths and measurements of equivalent width are given for 888 solar lines in the spectral region 1. 2.5 . The number of solar lines has been more than doubled, as compared with previous preliminary studies in this spectral region. The wave lengths of the solar lines are referred to those of the Fraunhofer lines in the visible and very near infrared spectrum by the method of overlapping orders. The root-mean-square errors of the infrared standard wave lengths, as derived from repeated measurements of individual lines, are +0.13 A for the l.6 region and +0.17 A for the 2.3 region. The equivalent widths are preliminary. The estimated errors are between 10 and 100 per cent, depending upon the degree of blending. About 470 infrared solar lines have been tentatively identified with atoms of H, K, C, At, Na, Si, Mg, Ca, Ni, and Fe and with first overtone lines of CO. Comparisons between solar wave lengths and those measured in the laboratory or predicted from term values reveal somewhat closer agreement, on the average, between the solar and the predicted values than between the solar and the laboratory values.
