[[claim-aikins-1902-ch11-quotes-jevons-conversion-rules-verbatim-then-rejects-rule-following]] and [[claim-aikins-1902-ch16-footnote-quotes-jevons-eight-syllogism-rules-verbatim-then-rejects-them]] both rest, at Tier 1, on Aikins's own 1902 text quoting and citing Jevons by page number — that part is solid. What is not yet confirmed is which specific Jevons title and edition those page numbers (p. 82, p. 83, and the eight-rule list) belong to. The numbering and content strongly resemble Jevons's *Elementary Lessons in Logic* (1870), a widely reprinted textbook, but Jevons's own text was not fetched this session to check exact page correspondence.

**What would resolve it:** a direct read of a digitized *Elementary Lessons in Logic* (1870, or a later stereotyped reprint using the same pagination) at pp. 82–83 for the conversion rules and its syllogism-rules section for the eight-rule list, checked against Aikins's quoted wording and rule order. If the page numbers or wording don't match, the correct Jevons title/edition needs identifying (candidates: *Elementary Lessons in Logic*, *The Principles of Science*, *Studies in Deductive Logic*).

**Why it matters:** low-stakes for the claims already recorded (they describe what Aikins wrote, not what Jevons wrote), but load-bearing if a future note wants to compare Aikins's transcription against Jevons's original — e.g. to check for OCR drift, paraphrase, or a rule Aikins silently reworded.
