    The first three columns of this table differ from the data already published by de Bray3 and by Mittelstaedt3 only in the use of 10 in place of 20 km./sec., for the probable error of Mittelstaedt's own work (Ann. Phys., 2, 285; 1929). He states explicitly on p. 310 of his paper that 20 km./sec. is his limit of error.

    J. Phys. Radium, 5, 168; 1924. In this case, also, the published ± 30 km./sec. appears to be an estimated limit of error, rather than a probable error.
