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"
A. MS., n.p., n.d., 12 pp.
A. MS., notebook, G-1903-2a, pp. 1-22.
Published, in part, as 1.15-26 (pp. 2-21). Gamma graphs, the third part of existential graphs, rendered intelligible
by CSP's categories of Firstness, Secondness, Thirdness.
And without the gamma graphs, multitude, infinity, and continuity are not easily explained. The peculiarity
of gamma graphs is that they make abstractions (mere possibilities) and laws the subjects of discourse.

A. MS., n.p., October 5, 1903, pp. 2-88 (pagination by even numbers only), incomplete.
Alpha part of existential graphs: permissible operations. The Beta part. Difference between alpha-impossibility and beta-impossibility summarized [cf. MS. 457]. The Gamma part concerns what can logically be asserted of meanings. The distinction between regulative and constitutive (in Kant). The logical doctrine called "Pragmatism." CSP claims that he has been unjustly called a sceptic, a second Hume. The "joke" about opium's dormitive virtue. Possibility and necessity (Locke's confusion). Qualities as mere possibilities. Relations are qualities of sets of subjects. Dyadic and triadic relations. All triadic relations are, more or less, thoughts. Doctrine of signs; icons, indices, and symbols.
