Excerpt from Logarithmic and Other Mathematical Tables Throughout the greater part of the book every tenth line is enclosed by parallel rules, and the other lines are grouped in threes. This gives the pages an open appearance, enabling one to find more readily the numbers sought, and securing in the trigonometric tables a symmetrical arrangement such that the order is the same in reading from the bottom of the page as from the top. The auxiliaries S and T, which are always used in connection with the logarithms of numbers, are conveniently placed at the bottom of pages 2 to 21, instead of in a separate table. Their arithmetical comple ments, CS and ct, are to be found on pages 62 to 64, adjacent to the logarithmic trigonometric functions with which they are used. The tables of addition and subtraction logarithms are based on those of Zech. The argument in each of these tables is obtained by subtract ing the smaller logarithm from the larger. The function is always added to the larger logarithm in addition, and always subtracted from it in subtraction. On account of these uniform ways of proceeding, these tables are more convenient than the Gaussian tables.
