On page 92, the patent named "Gas, scintillator for lighting" was numbered "204,28" in the original. The final "5" has been added because sorting the list reveals that the patent numbers form a consecutive series from 204,122 to 204,413, with the only one missing being 204,285. On page 92, the patent named "Shoetip" was guessed at; the "t" is unclear in the original. On page 94, the phrase "Alcohol Oxidized in the System." had no terminating punctuation in the original. On page 94, the illustration containing the words "Diamonds and Carbor", the "Carbor" may be an abbreviation for "Carborundum"; the image is unclear in the original. On page 94, in the advertisement for "WATSONS [sic] NON [sic] CHANGEABLE GAP LATHE", the abbreviation "MANR." had the "R" as a superscript in the original.
