capture promoted Tier 1 — see per-claim fields 2026-07-23

Does the 'Statistics' section (~p.35) of Richards' 1896 Aluminium monograph contain the $2/lb-1889 and $0.5/lb-1894 figures Hanners attributes to it?

Bottom line up front: yes. Where the prior capture (claim-richards-1896-preface-gives-different-aluminium-price-figures's source run) could not get the archive.org OCR text past the front matter, this session extracted the full 750-page PDF directly (extract_pdf, TLS verified) and located printed page 35 by its own running head. The "Statistical" table there contains both figures Hanners' paraphrase attributes to Richards, verbatim, in the same column.

Claim: Richards' 1896 "Statistical" table (printed p. 35) gives $2.00/lb for 1889 and $0.50/lb for 1894, matching Hanners' attributed figures exactly

The table appears directly beneath the running head "HISTORY OF ALUMINIUM 35" and the section heading "STATISTICAL," introduced by the sentence "The following table shows the price at which aluminium has been sold since it was first placed on the market." Reading down the "Per pound" column: 1889, Pittsburgh, $2.00; 1891, $1.50; 1892, $1.00; 1893, $0.75; 1894, $0.50; 1895, Switzerland, $0.35. This settles the specific question this capture was routed to answer — the $2/lb-1889 and $0.5/lb-1894 figures are not an invention or mistranscription by Hanners; they are a direct, correctly-transcribed read of Richards' own published table. The [unverified-quant — needs primary] flag on claim-richards-1896-preface-gives-different-aluminium-price-figures, which applied specifically to these two figures, is cleared by this finding.

Claim: The same table has no entry at all for 1884 — the popular sequence's $16/lb anchor year is simply absent from Richards' own price table

The table's full run of dated rows is: 1856 (Spring), 1856 (August), 1859, 1862 (two entries, Paris and Newcastle), 1878, 1886, 1887 (Bremen), 1888 (London), 1889 (Pittsburgh), 1891, 1892, 1893, 1894 (Pittsburgh), 1895 (Switzerland). There is no 1884 row of any kind. So while Richards' table independently corroborates the 1889/1894 half of the popular $16(1884)→$2(1889)→$0.5(1894) sequence, it supplies nothing for the 1884 anchor — that figure's sourcing (traced elsewhere in the vault to Skrabec 2017, see claim-skrabec-lockwood-disagree-on-1884-aluminium-silver-price) remains independent of, and unconfirmed by, this document.

Claim: Within Richards' own table, the 1889 and 1894 rows are both marked "Pittsburgh" (via ditto marks), i.e. a single-location series, unlike the two-source Wikipedia splice built around the same figures

The table marks place-names only where they change: "1889 Pittsburgh 2.00," then ditto-marked entries for 1891, 1892, 1893, and 1894, indicating all five 1889–1894 prices are attributed to the same market (Pittsburgh — home of the Pittsburgh Reduction Company, the Hall-process producer). This is a narrower and more internally consistent unit than claim-wikipedia-aluminium-price-sequence-is-a-citation-splice's finding that Wikipedia's version of these same two figures is stitched from two different secondary authors; within Richards' primary table itself, the 1889 and 1894 figures come from one continuous run in one place, which is a stronger evidentiary basis for the 1889/1894 pair specifically than the Wikipedia citation chain that led here.
