Abstract
ON looking through the recent brochure on the Gramme machine by M. Antoine Breguet, I observe that the author has appropriated, without acknowledgment, a large number of the beautifully executed Magnetic Figures which Prof. Silvanus Thompson has long since published, both in your columns (November 28, 1878) and elsewhere. So far as the eye can judge, M. Breguet's illustrations are printed from clichés of the very blocks used in Prof. Thompson's papers. If—as I understand was the case—M. Breguet's attention was called to the omission when he employed a similar illustration in a paper of his, which appeared some little time ago in the Ann. de Chimie et de Physique, the present oversight ought not to pass without some protest—the more emphatic as some of Prof. Thompson's figures are entirely new and of much theoretical and practical importance.
