[[strikethrough]] such as boxes, squares, or row of columns as this may be desired if this apparently simple form light and shadow be added the full delineation of the form of the object as present to the eye will be obtained
[[3 images]]. The square converted into a cube, the triangle into a pyramid, in the circle a globe, the shadow from the object in the plain in which it stands giving it projection and reality and may be varied, combined, and multiplied at the option and skill of the designer. thus the cut may be one of many such, or a part only of a more complicated figure a portion of a flight of steps, a box - or a building - the triangle, a pyramid a tent in many such [[?]], seen at different distances and the circle a funnel, a globe., or continue with other [[?]] and aid in the representation in a variety of ways. to the [[strikethrough]] representation [[/strikethrough]] of other familiar objects.

This the most simple is at once one of the most important and simple elements of the knowledge of form, many cubes as seen a different distance combined together [[?]] portion of flight of steps. and is at once a simple cube - pillar a box or the quantities for the largest Edifice, or a row of them, or the space and quantity even on a [[?]] or a simple drinking cup

number one. is the simple cube.  as a seen below the horizon line. therefore showing The top. and the same with its apelations in the same figure - this and all such forms are general from nature drawn by the aid of the eye alone - aides perhaps by a Knowledge of perspective in the mind. but the eye if correct will alone trace it with considerable accuracy. but where actual measurements geometrically accuracy are required it is always drawn by the aid of the lines, there-by eye alone, it may be obtained with reasonable accuracy be found by making the square as  seen directly in from. [[image]] A B C D then from point B carry up another [[?]] for the side, and to decline the point C, hold a pencil or flat stick horizontal before the eye even with the extreme angle, or corner of the object, when that intersects with line D, will be the height up or perspective delineation of the [[?]] lower angle. Draw the line from the course of the square to it, and the line to C is obtained delivered in a [[?]] as they may rise or fall below the front square this repeated on the other angles completes the figure, but if great accuracy is desired then the perspective lines are drawn in thus
[[image]] B C A the horizon line 
B. the place selected for the front of the object or square. C the point of sight on the horizon line to which all the side lines except the perpindicular converge and from which the line are to be carried to the angle of the square as designated by the double lines, the width of the sides and top being determined by another line, carried to another point called the point of distance the intersection giving the required mark and the relation of the form is continues as seen.
