Abstract
IN NATURE, vol. xix. p. 172, Mr. Ellisgives, on the authority of M. Cavaillé-Coll, a rule determining a point of some interest in regard to organ-pipes. All those who are accustomed to organs know that the theoretical rule which makes the vibration-number of the note sounded vary inversely as the length of the pipe, does not hold correctly in practice, as the pitch is influenced by the transverse dimensions. A pipe of “large scale,” i.e., of large diameter, will speak a lower note than one of “small scale,” the length of the tube being in both cases the same. I am not aware that this fact has been explained in acoustical works, or any rule given for the variation.
