Transcriber’s Notes:

The spelling, punctuation and hyphenation are as the original except
for apparent typographical errors, which have been corrected.

  Italic text is denoted _thus_.
  Bold text is denoted =thus=.
  Bold, sans serif text, representing physical appearance e.g., of a
  ‘Vee’ shaped thread is denoted thus ^V^.
  Subscripts are denoted thus _{1}.

Some page numbers printed in the original ‘Index to Part One’ do not
appear in the body of the book. The transcriber has endeavoured to
make assumptions as to the most appropriate anchor locations. The
appearance of the original index has not been changed.

Examples (possibly relocated, by the author, into Part Two) are:

  =Air=, des., composition of, 15, 16
  =Air pump=, 13
  =Nitrogen=, what part of air, 15
  =Oxygen=, what part of air, 15

  =Value of Reidler belt-driven pump=, ills. and des., 238-240
  changed in the Index to:-
  =Valve of Riedler belt-driven pump=, ills. and des., 238-240

All references to ‘Reidler’ pumps have been corrected to ‘Riedler’
(Alois Riedler, 1850-1936, Austrian professor of engineering).
