Abstract
IT is remarked in NATURE, vol. xi. p. 404, that Walker's “generating” circle appears to have dropped out of recent textbooks; but I may be allowed to add to the statement of your reviewer that Walker's method was revived in the Messenger of Mathematics, vol. ii. p. 97. I had been acquainted with his method for some years previously, and had communicated it to several mathematicians, but omitted it from my elementary “Geometry of Conics” (1872), hoping that I might soon have leisure to develop it more fully in a larger work. Shortly before the publication of my article in the Messenger, Mr. R. W. Genese rediscovered the circle and its properties. Mr. Day uses this circle in his work on the Ellipse (1868), but has overlooked one of its characteristic properties.
