Abstract
THE section on the analysis of sounds in Prof. Abderhalden's extensive “Handbuch” is written by Dr. E. Budde. It contains accounts of the use of mechanical integrators for the analysis of a periodic curve, and of the method of calculating the terms of the Fourier series from ordinates at regular distances apart. Tables are given to facilitate the calculation when seventy-two ordinates are measured per period. It is not often that so many ordinates are taken, but when it is necessary or desirable the tables will save much time and trouble.
