Abstract
MR. TAYLOR's present work is by no means a second edition of his “Geometrical Conies”(1863). His object in this volume is a highly laudable one; from more than one quarter has recently come the complaint that the subject of geometrical conic sections is in an unsatisfactory state. The work under consideration is stated to be “the result of an attempt to reduce the chaos of geometrical conies to order, the subject having suffered not a little from desultory treatment.” As in the earlier treatise, our author does not define the conies in question to be sections of a cone; and here he is at direct issue with Mr. Jackson:—“I am unable, despite his skilful advocacy, to acquiesce in the primary definition of conies from the solid.”
