Chap. CLX.Of demonstrative Gestures.

The action by which a figure points at any thing near, either in regard to time or situation, is to be expressed by the hand very little removed from the body. But if the same thing is far distant, the hand must also be far removed from the body, and the face of the figure pointing, must be turned towards those to whom he is pointing it out.
