An Attempt to state systematically the Doctrine of the Census in Geometrical Topics or Topical Geometry, more commonly called "Topologie" in German books; Being A Mathematical-Logical Recreation of C. S. Peirce following the lead of J. B. Listing's paper in the "Göttinger Abhandlungen"

The interpretant is created by the sign; and since the sign as such determines the interpretant, it is in some sense represented in the sign, that is, it is called up by the sign while in itself it is acted on by the sign. It is so acted upon as to represent the sign to be a sign of the object. Thus, while the object is bifiss, the interpretant is trifiss or trifissile.

The object is something external to and independent of the sign which determines in the sign an element corresponding to itself; so that we have to distinguish the quasi-real object from the presented object; or as we may say, the external from the internal object. And the external object as it is in itself is to be distinguished from the feature of the external object that is represented.

Representation, by which I mean the function of a sign in general, is a combinant, or trifile, relation; since it subsists between the sign, the object represented, and the interpretant or sign of the same object determined by the sign in the mind of the person addressed, or in other field of signification.
