URL: https://sacred-texts.com/earth/za/index.htm Searched: the index page only (the full etext is on the site, chapter by chapter). Result: positive (the inventor's own work, a later edition).

Found [web: https://sacred-texts.com/earth/za/index.htm]: - A full etext of the third edition (1881), about 430 pages, against the 1865 second edition of 221 pages held in the project folder. The site's editor gives the edition history as: a 16-page pamphlet (1849), 221 pages (1865), 430 pages (1881). The editor's introduction is commentary by a critic (the site owner), not the inventor's text. - The editor says the 1881 edition "hints at" the Hampden-Wallace affair. If so, the 1881 text is the inventor's own later statement bearing on the 1870 test. - A "Preface to the Second Edition" page also appeared in the Google results (https://sacred-texts.com/earth/za/za02.htm or similar; not opened). - Wikipedia cites 1881 "Chapter II: Experiments Demonstrating the True Form of Standing Water" from this site.

Bearing: priority 1. The 1881 edition roughly doubles the text. A Sonnet deep read should compare its Bedford Level chapter, its refraction passages and its Plymouth and Eddystone account with the 1865 book. In particular, check whether the 1881 edition answers refraction or Wallace's 1870 result. Not done in this run.
