According to McKay, Hutchinson & Co. published the first edition of THE WAY OF THE SPIRIT in London on May 6, 1906; 15,000 copies, without illustrations. Ads at the end of the book are dated February 1906.
Scott claims the Hutchinson first edition was published March 9, 1906. Whatmore agrees with Scott, and adds a note claiming that "the Hutchinson Catalogue in fact says '9 Mar 05' but this is impossible."
Higgins claims that Hutchinson paid £750 ($129,000 in 2020 dollars) as an advance for publication in book-form.
This novel was not published in America.
The Musson Book Company published the first edition in Canada also in 1906. Ads at the end of the Musson first edition are the exact same as those found at the end of the first British edition.
