Leeds. The revision was thereafter continued single-handed, with the help
of very full notes which Mr. Leeds had prepared, by the undersigned. It
had been agreed prior to Mr. Leeds' death that it would add to the
utility of the work if descriptions of a number of representative
acetylene generators were given in an Appendix, such as that which now
appears at the conclusion of this volume. Thanks are due to the numerous
firms and individuals who have assisted by supplying information for use
in this Appendix.
