Abstract
THIS is a neat little treatise on the conic sections, containing—what appears to be a novelty—a method of plane projection, to which the authors give the name of Focal Projection. The remarkable feature of the book is, that the authors, who are evidently well up in these curves, should not be acquainted with the writings of the present master of St. John's College, on the same subject. No one who has looked into Dr. Taylor's recent works, could be unacquainted with what he has said upon the contributions of Boscovich and G. Walker, and would hardly use the “generating circle” of a conic in the same fashion as Boscovich does, and write, after the definition, “which we have called the auxiliary circle of a point.”
Conic Sections Treated Geometrically.
