Less misleading, perhaps, to say that there are two drafts of pp. 29-54 and that it is not certain which should be counted as completing pp. 1-28. Pages 45-53 of one of these drafts were published as 1.288-292. See G-1905-1c. Not published is the first part of the manuscript which follows the third of the Monist articles very closely. Theory of signs. Relation among thought, thinking, and Signs. Application of the type-token distinction. Diagram of thought, with some conventions for diagramming. The meaning of a conditional proposition and the revision of the tychistic hypothesis. The "second" draft is similar to the first in respect to the conventions for the diagramming of thought. Restatement of chief purpose for constructing algebras of logic and existential graphs. Sketch of a classification of signs.
