One part of his exercise (Sutton 2014, Nullius in Verba, ThinkerMedia, chapter 4, don't buy it, it's not worth it) was to find sources that cite Matthew (1831). Six of these sources, he claimed "specifically drew attention to Matthew's discovery of the natural process of selection on species" (Sutton 2014, chapter 4). His conclusion is that anybody who is interested in the question of the origin of species must, on seeing any these sources, necessarily and immediately buy Matthew's book and search it for information on this very topic. The following lists these sources from Sutton (2014, chapter 4) with comments added, where Sutton's premises are evidently false (tl;dr? Scroll to end).
Anon — Edinburgh Literary Review
"We have always considered it as a fortunate circumstance, when an author has the talent of delineating his own character, and especially in the front of his book, which saves a reviewer much trouble. We shall, therefore, give Mr Matthew's Preface entire, as it is short, and conveys a tolerable taste of his style and genius.—
'It may be thought presumptuous in a person who has never had the curiosity to peruse the British classic authors on planting and timber,—Evelyn, Hanbury, Marshall, Miller, Pontey,—to make experiment of the public sufferance. The author does not, however think any apology necessary; as, if the public lose time unprofitably over his pages, he considers the blame attachable to them, not to him. A writer does not obtrude as a speaker does, but merely places his thoughts within reach.
As the subject, notwithstanding its great importance, might be felt, per se, dry and insipid by the general reader, accustomed to the luxuries of modern literature, the author has not scrupled to mix with it such collateral matter as he thought might serve to correct the aridity. The very great interest of the question regarding species, variety, habit, has perhaps led him a little too wide. [...]' "
Firstly, this anonymous reviewer did not draw attention to Matthews ideas on natural selection. He just replicated the full preface of Matthew (1831), in order to show his readers, what a prick Matthew was.
Secondly, contemporary readers could not necessarily have told, from this preface, that the book said anything about natural selection transforming species, varieties or habits. Back then, many books dealing with natural history said something about species, varieties and habits. But if natural selection or an equivalent thereof was mentioned in connection with this species problem, then as a force keeping the species fixed and preventing their transmutation. Sutton thinks the contemporary readers must have understood: "the question regarding species, variety, habit," as a hint of Matthew at his idea that natural selection plays a role in transforming species, because he does understand it thus now. The ruling paradigm, however, saw natural selection and species transmutation as mutually exclusive. Therefore, contemporary readers may well have gathered the opposite from this 'hint.'
Surely, the reviewer did not intend to raise anybody's attention to the idea of natural selection in Matthew (1831). On the contrary, the rest of this review details each part of Matthew's book, but only mentions things concerned with practical matters of tree training or Matthew's offenses, slander and plagiarisms (yes, see footnote at page three of this review).
Currently unknown — The Elgin Courier
" 'This work contains a great variety of interesting information. We have perused, with much interest and gratification, the speculations therein contained, in reference to the moral and physical constitutions of the human race.'—Elgin Courier."
Again, I fail to see why a contemporary reader should necessarily take this as a hint at natural selection transforming species. Speculations about the moral and physical constitutions of the human race could probably have meant many things to contemporary readers. As mentioned above, natural selection and species transmutation were taken to be mutually exclusive things. To think that contemporaries must have understood this like we would, today, is retrospective bias (Whiggishness).
John Loudon — Publisher, naturalist, botanist, garden designer and polymathAdmittedly, Loudon's review (see here) shows that he did get the message about natural selection and the origin of species, but even he had his doubts about what it meant:
"One of the subjects discussed in this appendix is the puzzling one, of the origin of species and varieties; and if the author has hereon originated no original views (and of this we are far from certain), he has certainly exhibited his own in an original manner."
Loudon knew the idea of natural selection from its established context of natural theology, that is, as a force keeping species fixed (see here). So, while Loudon did raise attention to that part of Matthew's book, he may well have not agreed or not understood Matthew's idea of the role of natural selection in transforming species.
Anon. United Service Journal
"In thus testifying our hearty approbation of the author, it is strictly in his capacity of a forest-ranger, where he is original, bold, and evidently experienced in all the arcana of the parentage, birth, and education of trees. But we disclaim participation in his ruminations on the law of Nature, or on the outrages committed upon reason and justice by our burthens of hereditary nobility, entailed property, and insane enactments."
Again, the law of nature could mean anything to a contemporary reader and the association with "outrages on reason and justice committed by hereditary nobility and entailed property" will not have helped those readers to take this as a hint at natural selection and the transmutation of species.
Adam Black — Matthew's Edinburgh Publisher
"In embracing the Philosophy of Plants, the interesting subject of Species and Variety is considered,—the principle of the natural location of vegetables is distinctly shewn,—the principle also which in the untouched wild "keeps unsteady nature to her law," inducing conformity in species, and preventing deterioration of the breed, is explained,—and the causes of the variation and deterioration of cultivated forest-trees pointed out."
To contemporary readers, this clearly suggests Matthew's book to be one more installment of the old natural theology paradigm.
Longman, Rees, Orme, Brown and Green — Matthew's London Publisher
It has been claimed that six publications or adverts from before 1858 "specifically drew attention to Matthew's discovery of the natural process of selection on species." However, five of these did not do so. Only Loudon's review might have drawn the attention of a reader being interested in this specific issue to this specific book.
