Abstract
THE authors of these tables have attempted to avoid the necessity of employing difference columns. With this end in view, numbers are printed on one side of a graduated line, drawn down the page, and the corresponding logarithms are placed opposite to them. The difference between successive printed numbers is 10 and the intermediate spaces are divided into ten parts. The logarithms are also printed at intervals of ten, and the correct subdivisions are indicated. It is claimed that more accurate readings will be made in this way than from the ordinary tables where a slight error in the fourth place occasionally occurs. But we must confess that we have found this new method a considerable strain on the eyesight, and there is the additional inconvenience of having three pages to consult instead of one. For practical purposes, ordinary tables give a sufficient degree of accuracy; we therefore doubt whether this new graphic system, in itself distinctly ingenious, will receive much support.
