Abstract

(1) MR. CASTLE is well known as the author of a series of elementary text-books on mathematics. He now gives us a new set of five-figure mathematical tables. So many tables of this sort have appeared of late years that innovation in this field is rather difficult. Mr. Castle's tables are very similar in contents to Dale's five-figure tables, with the advanced functions cut out. One hapiv alteration is that, in the early part of the table of logarithms, mean differences are calculated for every five entries instead of for every ten. This renders-possible the use of mean differences in all parts of the table without loss of accuracy. Another good point is a table of degrees and circular functions for equal intervals of radian measure; this should be most valuable for advanced work.
