  |                                                                   |
  |Formatting and coding information:                                 |
  |  - Text in italics is marked with underscores as in _text_.       |
  |  - Bold-face text is marked =text=.                               |
  |  - Superscript x and subscript x are represented as ^{x} and _{x},|
  |    respectively.                                                  |
  |  - sqrt(x) represents the square root of x.                       |
  |  - [oe] and [OE] represent the oe-ligatures.                      |
  |  - Greek letters are written between square brackets, as in [tau] |
  |    or [theta].                                                    |
  |  - Overlined 1 is represented as [=1].                            |
  |  - [<] represents a 'rotated [Delta]'.                            |
  |                                                                   |
  |General remarks:                                                   |
  |  - Footnotes have been moved to directly below the paragraph they |
  |    refer to.                                                      |
  |  - In-line multiple line formulas have been changed to in-line    |
  |    single-line formulas, with brackets added when needed.         |
  |  - The Table of Contents has been corrected to conform to the text|
  |    rather than to the original Table of Contents.                 |
  |  - The table on operating costs of trains gives 'Other expenses   |
  |    per square mile.' This has been changed to 'Per mile' the same |
  |    as the other expenses.                                         |
  |  - The table on dimensions of farm and road locomotives gives the |
  |    diameter of the boiler shell as 30 feet, which seems unlikely. |
  |  - Feet are sometimes used as unit of area, both knots and knots  |
  |    per hour as unit of speed.                                     |
  |                                                                   |
  |Changes in text:                                                   |
  |  - Reference letters in the text have in several cases been       |
  |    changed to conform to the letters used in the illustrations.   |
  |  - Minor typographical errors have been corrected.                |
  |  - Except when mentioned here, inconsistencies in spelling        |
  |    and hyphenation have not been corrected. Exceptions:           |
  |      'Desagulier' to 'Desaguliers'                                |
  |      'Seguin' to 'Seguin'                                         |
  |      'Goldworthy Gurney' to 'Goldsworthy Gurney'                  |
  |      'Ctesibus' to 'Ctesibius'                                    |
  |      'i.e.' to 'i. e.'                                            |
  |      'Warmetheorie' to 'Waermetheorie'                             |
  |      'tour a tour' to 'tour a tour'                               |
  |      'the beam passes to the' to 'the steam passes to the'        |
  |      'Desagulier' to 'Desaguliers'                                |
  |      'elever' to 'elever'.                                        |
  |  - 'As early as 1743' moved to new paragraph.                     |
  |  - 'A = 6.264035' changed to 'a = 6.264035.'                      |
  |                                                                   |
