    L. M. Milne-Thomson & L. j. Comrie, Standard Four-Figure Mathematical Tables, London, Macmillan, 1931. W. J. Eckert, in “Air Almanacs,” Sky and Telescope, v. 4, p. 12-15, 17, Nov. 1944, shows that the French air almanac uses such a device, but one which, in the writer’s opinion, is inferior to that of Milne-Thomson & Comrie, because the last figure must be altered in some cases, when accuracy to the nearest minute only is desired. The writer has discussed a new kind of “critical graph,” which is used in the same manner as a critical table but can be read to greater accuracy, if need be, in “The Air Almanac refraction tables,” U. S. Naval Institute, Proc. v. 70, Sept. 1944, p. 1140-1141; Univ. Calif., Los Angeles, Astronomical Papers, no. 5.
