A Method of drawing a deformed Figure, which will appear well proportioned from a certain Point of View.

Draw any thing you may fancy on a thin white pasteboard; then prick it; afterwards put the same on an horizontal surface, which we will suppose to be another pasteboard. Put a lighted candle behind that drawing, and draw on the horizontal surface the lines given by the light: this will give a deformed design. This being done, take away the drawing that was pricked and the candle; then place your eye where the light was, and you will see your drawing assume a regular form.
