To find the shadows upon the surfaces of bodies occa-sioned by the privation of the sun’s rays, ii. 424.
Given the vanishing line of a plane, the vanishing-pointof the sun’s rays, the vanishing-point of the seat ofa ray on the plane, the representation of a pointin space, and the representation of the seat of thepoint in the plane whose vanishing-line is given jto find the representation of the shadow upon theplane of the picture, ii. 424.
Given the inclination of a plane to the plane of thepicture, both being perpendicular to the originalplane, and the seat and inclination of a straight linein the plane of the horizon ; to determine the vanish-ing-point of the seat of the line on the vertical plane,and the vanishing-point of the line, ii. 425.
To find the shadow of a cylinder lying with its convexsurface upon a horizontal plane, ii. 425.
To find the shadow of one cylinder upon another. Thecylinder which throws the shadow, and that on whichthe shadow is thrown, being placed, the former withits end and the latter with its convex surface uponthe same horizontal plane, ii. 425.
To find the shadow of a building with a break, ii. 426.
Projection, ii. 328.

Given the representation of three rectangular plan® 3forming a solid angle; the representation of a pointof light or candle, and the seat of the light on one ofthe planes ; to find the seat of the light on the othertwo planes, ii. 428.
Given the representation of a line perpendicular to theoriginal of the plane, and the vanishing point of theline, and the point where the line meets the plane,a luminous point with its seat also upon the plane ,to find the shadow of the line upon the said plane,ii. 428.
