Both referees' report that it requires editing prior to publication in Proceedings of the Royal Society, with Miers detailing places where the manuscript is incomplete or incorrect, and Walker listing inessential illustrations that Professor Joseph Larmor proposes be omitted. The paper is sent to Shuster, at Larmor's direction, so that necessary editing may be carried out before they proceed to printing. 10 October 1907
