Abstract
ANY practical means of assisting the computer is to be welcomed, and this volume of natural sines to every second of arc, and to eight places of decimals, will be sure to have a considerable practical value, even to those who use machines. The sines to 10″ are those from the “ Opus Palatinum of Rheticus” (published 1596); the sines to I″ were interpolated by the Thomas calculating machine being copied to ten places. The table is arranged like Chambers' log tables, the figures to the right of the seconds being prefixed to each of the sets in the same horizontal line, except when the sets are dotted, when the first four digits are taken from the line below. Considering the laborious nature of, and the accuracy required in the construction of these tables, the compiler is to be heartily congratulated on the successful completion of the task.
