Page 141 - Bimodulus" is exactly double the modulus of any system of logarithms. The method is derived from the familiar proposition that, when the difference of two numbers is small, the difference of their logarithms is nearly equal to the bimodulus multiplied by the difference and divided by the sum of the numbers.

From the time when the reprint of Lalande appeared (about twelve months ago) I have heard no one contest this position ; and the present work will show that it is true of a heavy page (as the printers call it) as of the one in which there are...
