'THE Council of Military Education in their official reports denounce the knowledge of geometrical drawing exhibited by the candidates for admission to Woolwich as being vague and unsatisfactory in its na ture and extent, as desultory, and ill-calculated to enable them, after joining the academy, to proceed at once with their Artillery and Engineer studies; and, say they, this state of affairs must arise from the absence of any English work treating of the subject of geometrical drawing in anything like a practical manner. This want Mr. WINTER has now supplied. The first part of his treatise dealt with the plane geometry; the second completes his work by embracing the practical geometry of planes and solids, and its application to horizontal and isometric projection, and the projection of solids and shadows. The system adopted

by the Author avoids the error of considering that sufficient instruction is afforded in such matters, provided the pupil learns how to do a thing, however ignorant he may be of the principles of the theory on which his methods are based, and of the properties and reasoning which prove those methods to be right. In publishing a work which exhibits clearly the leading principles of both plane and solid geometry, and the manner in which those principles are applied to the solution of practical questions, and especially those involved in the prescribed form of military education as at present laid down, Mr. WINTER has conferred a boon on the scholastic profession in general, and on military students in particular; and has, moreover, contributed a valuable ad dition to English educational literature.'
