Footnotes have been moved to the end of the chapter.
In-line multiple line formulas have been changed to in-line single-line formulas, when necessary with brackets added.
The Table of Contents has been corrected to conform to the text rather than to the original Table of Contents.
The table on dimensions of farm and road locomotives (page 358) gives the diameter of the boiler shell as 30 feet,
which seems unlikely.
The table on operating costs of trains (page 376) gives Other expenses per square mile. This has been changed to
Per mile, the same as the other expenses.
Feet are sometimes used as unit of area, both knots and knots per hour as unit of speed.
Changes in text:
Minor typographical errors have been corrected.
Reference letters in the text have in several cases been changed to conform to the letters used in the illustrations.
Except when mentioned here, inconsistencies in spelling have not been corrected. Exceptions:
Desagulier to Desaguliers;
Séguin to Seguin;
Goldworthy Gurney to Goldsworthy Gurney;
Ctesibus to Ctesibius;
i.e. to i. e.;
Warmetheorie to Wärmetheorie;
tour a tour to tour à tour;
the beam passes to the condenser to the steam passes to the condenser;
éléver to élever.
