| TRANSCRIBER'S NOTES: |
| |
| |
|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.' |
