Shaw's Civil architecture; being a complete theoretical and practical system of building, containing the fundamental principles of the art . pointsF H K; through the points D, F, H, K, draw linesD rf, F /, H //, and K k, perpendicular to the diam-eters, cutting them at the points d, f, h, k; andthrough the points A k, h, /, d, draw a curve, whichwill be the edge of one half of the shadow, fromwhich the other half may be drawn, as is shownby the figure; and this will give the shadow com-plete. OBSERVATIONS. I have given one example of the cflect of light andshade on mouldings of different curvature: I shallendeavor to show the effect of light and shade alsoon many other examples, especially on the five ordersof Architectiue. From what has been said on this subject, manypractical and useful rules in shadowing may be de-duced ; but as I have far exceeded the bounds firstassigned for this part, I must end with observing,that, from a consideration of the foregoing examples,the shadows of all objects, however complicated, maybe found, as every object may be considered as com-pounded of prisms, cylinders, spheres, and annuluses;.
