of the book that do not refer to those later sections, with their final section designation and page numbers, are, This then would comprise the originally intended book, and the printed manuscript, pre-July 1830, a book on timber and marine, with a critique of competitors. Matthew then submitted his manuscript, then forgot all about it, distracted by the political and civil unrest on the continent, as he explains in his later addition, specifically the final paragraph of colophon, on the last page of the book. Second instalment It is reasonable to suggest that material that mentions issues relating to those developments in France were added subsequent to the submission (all mentions of France are in the appendices; entail is mentioned twice in quick succession in the introduction). In support, Note B is referenced from Note C (p. 374). This would then constitute a 2nd draft, after the July Revolution, likely adding the following in its final form, as these sections are unaffected by later additions, This then produced in total a book on timber and marine, critique of competitors and a scathing attack on entail. It is possible that the second instalment included the part described below for a mooted third instalment. There is no significance of there being just one, or two later instalments. While what is nominally called the third instalment here appears to have been added to the book after the second, it is possible that they may have been submitted simultaneously. Another potential is that just the final section of the main part of the book, the fifty-page review of Cruickshank's Practical Planter, was submitted alone, then the final instalment contained everything remaining, which would have significantly expanded the evolutionary component. Possible third instalment There are several phenomena that are confusing when considering the sequence of events in constructing this book. There is the mystery of a spacing bar positioned after a line break at the end of NOTE F, then another line spacing, before the beginning of an addendum (essentially the appendix to the appendix, although all the signs suggest it being added later). It is even reasonable to consider the addendum as being added as an afterthought, following the second version of Matthew's manuscript. This is suggested by the colophon in that third instalment which mentions the material that was included to date. Additionally, the new material is not integral to the appendix that
