Not indexed. Not illustrated. 1912 Excerpt: . . . confirm those in H. A. 44, as might be expected since the observations were made under the same conditions. The average deviation of the 36 residuals is 46. The observations in H. A. 46 were made under similar conditions to those in H. A. 34, and, therefore, we should expect similar systematic errors. The effect of color, red stars measuring too bright, is more marked in H. A. 46, but the effect of magnitude in the latter volume is insensible. H. The correction for color, in the Catalogue of Sir William Herschel, is very small. This may also be expressed by saying that he was not color blind, but that his impression of the relative intensities of different colors was nearly the same as that of the observers here. The error due to the grouping, by which faint stars appear too bright, is well marked. h. The curves derived from Sir John Herschels observations are less smooth than in the preceding catalogue, partly because the number of stars is less. Red stars are observed, relatively, rather faint. As his observing list consisted mainly of bright stars, the faint stars included are generally those which he estimated too bright. The systematic errors for these stars are, therefore, large and negative. The residual 66, for magnitude 6. 5, is too large to be entered in Figure 4. 0. The Uranometria Oxoniensis is an important catalogue, and it furnishes a wholly independent test of the scale of the meridian photometer. The form of instrument, method of observation, location, and observers, all differed from those used here. Even the methods of comparison were unlike, disappearance of images being used in this work, and equality of images in that of the meridian photometer. The agreement in color is excellent, the extreme differences in the last line only amountin. . . This item ships from La Vergne,TN.<
