It is essential, therefore, that the student should possessa certain familiarity with the forms of the regular solids, toassist him in the classification of the objects that he will becalled on to develop. It is with this end in view that a seriesof plates is to be drawn by the student. The instructionis in the form of problems, and several of the drawingsof Practical Projccticm are reproduced for the purpose ofshowing the development of t
