GRAMMIGRAPHIA;

Cj)t Grammar of Bratoing.

DRAWING

REPRESENTS WHAT IS SEEN BY LINES,

viz.

THE APPARENT RELATIVE MAGNITUDE, POSITION,

AND FIGURE.

THE REAL MAGNITUDE AND SITUATION CANNOT BE VIEWED FROM ANY ONE
POINT, OF COURSE CANNOT CORRESPOND WITH THE APPEARANCE.

THESE TWO PARTICULARS

MUST THEREFORE BE SEPARATELY CONSIDERED AS FOLLOWS:

PART THE FIRST.

THE APPARENT MAGNITUDE, DISPOSITION, AND FIGURE,

WHICH DIRECT THE REPRESENTATION IN DRAWING.

PART THE SECOND.

THE REAL MAGNITUDE AND SITUATION, WHICH APPOINT
THE RULES THAT GOVERN APPEARANCE.
