Introduction, pp. -12
INTROD UCT ION. 9 ideas, Which the complete knowledge of the whole would naturally have given us, if we had confidered it in the other way before. Another advantage of confidering obje&s thus merely as fhells compofed of lines, is, that by thefe means we obtain the true and full idea of what is call'd the out- lines of a figure, which has been confin'd within too narrow limits, by taking it only from drawings on paper; for in the example of the fphere given above, every one of the imaginary circular threads has a right to be confider'd as an out-line of the fphere, as well as thofe which divide the half, that is feen, from that which is not feen ; and if the eye be fuppofed to move regularly round it, thefe threads will each of them as regularly fucceed one another in the office of out-lines, (in the narrow and limited fenfe of the word:) and the inftant any one of thefe threads, during this motion of the eye, comes into fight on one fide, its oppofite thread is loft, and difappears on the other. He who will thus take the pains of acquiring perfe& ideas of the diftances, bearings, and oppofitions of feveral material points and lines in the furfaces of even the mofi irregular figures, will gra- dually arrive at the knack of recalling them into his mind when the objecs themfelves are not before him: and they will be as ftrong and perfe& as thofe of the moft, plain and regular forms, fuch as cubes and fpheres ; and will be of infinite fervice to thofe who invent and draw from fancy, as well as enable thofe to be more corre& who draw from the life.
