The Corinthian capital in fig. will require little more than inspection toimderitand the construction of its sciography ; and all that we think necessary to particu-larise are the developed projections A, B, C, D, E, F of the abacus and the leaves, whereonthe termination of the shadows at angles of 54° 44, as explained in Jig. 856., give theirrespective depths on the elevation. There is another method of arriving at the result here exhibited, by drawing sectionallin(t^, parallel to the direction of the light through the different parts and leaves of tlie Chaf. IV.

It however induces such a confusion of lines, that we have long since aban-doned it, and have no hesitation in recommending the process here given as the best andmost likely to avoid confusion. It is of course unnecessary, in making drawings, to than the shadow of one capital, as in a portico, or elsewhere, similar capitals, similarlyexposed to the light, will project similar shadows, so that the projection on one serves forthe projection on all of them. 2484. For instruction upon the mode in which reflected light acts upon objects in shadeand shadow, we must refer the learner to the contemplation of similar objects in reliefJlie varieties of reflexes are almost infinite ; and though general rules might be laid
