Chap. CCCXLVII.—Why, on measuring a Face, and then painting it of the same Size, it will appear larger than the natural one.

A B is the breadth of the space, or of the head, and it is placed on the paper at the distance C F, where the cheeks are, and it would have to stand back all A C, and then the temples would be carried to the distance O R of the lines A F, B F; so that there is the difference C O and R D. It follows that the line C F, and the line D F, in order to become shorter [93], have to go and find the paper where the whole height is drawn, that is to say, the lines F A, and F B, where the true size is; and so it makes the difference, as I have said, of C O, and R D.
