Note
The differences between the text of the Apologia pro Vita sua of 1864 and the History of my Religious Opinions of 1865, so far as the two books overlap, are shown in pp. 87-477 of this edition, in the following way:
Words or passages in the 1864 book which were cancelled in 1865 are enclosed in square brackets [ ].
Words or passages first inserted in the 1865 book are enclosed in angular brackets < >.
Words or passages of the 1864 book, not simply deleted, but replaced by other words in 1865, are left untouched in the text, but the alteration is shown in a footnote, preceded by the number of the line where the difference occurs, the 1864 version being given first, followed by the 1865, thus (on p. 264):
24 made to eat] forced to recognize
The 1864 text can therefore be constructed by omitting all words enclosed in < >, by including all words in [ ], and by ignoring the footnotes.
The 1865 text can be constructed by omitting all words enclosed in [ ], by including all words in < >, and by reference to the footnotes.
A few differences between two copies of the 1864 book (one probably, though not ascertainably, representing the original pamphlets, and the other the pamphlets revised for reissue in book-form) are also shown in the footnotes; and by the courtesy of the Newman Trustees, and of Messrs. Longmans, Green & Co., some other interesting variations, subsequent to 1870, are given.
