From the Robin Catalogue:
A. MS., G-1893-5, pp. 85-141 (pp. sog, 130 missing), with 8 pp. of variants.
Published, in part, as 4.53-56 (but not all of 56) and 4.61-79 (pp. 91-141, with deletions). The unpublished pages concern terminology mainly: term, concept, proposition, judgment, argument, and the operation of naming. As an aside, CSP’s low opinion of the logical powers of the Germans.
