• It quotes the 1905 edition, p.27: "Задачу тяготения и задачи всей энергетики нельзя представить реально решёнными без реального понимания эфира, как мировой среды, передающей энергию на расстояния..." (the problem of gravitation and of all energetics cannot be really solved without a real understanding of the ether as the world medium that transmits energy over distances, and that cannot be had without treating the ether as an elementary substance).
• It shows a photograph captioned as the cover of the brochure and its periodic table, held at the Polytechnic Museum, Moscow. This is an artifact location to record.
• It says the ideas also appear in the 8th edition of Основы химии (1906).
• It gives the mass range 9.6e-7 to 5.3e-11 of the hydrogen atom and the quotation "close to one millionth ... about 2250 km per second". Both match the English deep read.
• A statement to check against the project's documents. The article says that neither the essay nor the 7th and 8th editions of Основы химии put newtonium and coronium in their periodic tables, because evidence was lacking. The project's English 1904 copy (page images p.32, p.34 in the deep read) does print x and y in the table. Habr's photograph of the 1905 table also shows x and y. So the Wikipedia statement is contradicted by the primary scan for the essay; it is unchecked for the textbook editions.
• It credits Ramsay with suggesting the zero group. The 1905 Russian footnotes credit Errera (1900) with the first mention and Ramsay with the atomic-weight comparison (19 March 1900).

Bears on

Claim 2 (where x and y were printed), and the historical record (artifact in the Polytechnic Museum; the 1906 textbook as a later statement).
