[Footnote II-79: Dissertation, pp. 29-32. The many mistakes which Fournier commits in his Dissertation, excite a suspicion that he was either superficially acquainted with his subject, or extremely careless. He published two or three other small works on the subject of engraving and printing,--after the manner of “Supplements to an Appendix,”--the principal of which is entitled “De l’Origine et des Productions de l’Imprimerie primitive en taille de bois; avec une refutation des préjugés plus ou moins accredités sur cet art; pour servir de suite à la Dissertation sur l’Origine de l’Art de graver en bois. Paris, 1759.”] The fact having been established that in one of the editions of the Speculum a part of the text was printed from wood-blocks, while the whole of the text in the other three was printed from moveable types, Heineken, without diligently comparing the editions with each other in order to obtain further evidence, decides in favour of that edition being the first in which part of the text is printed from wood-blocks. His reasons for supposing this to be the first edition, though specious in appearance, are at variance with the facts which have since been incontrovertibly established by Mr. Ottley, whose scrutinizing examination of the different editions has clearly shown the futility of all former speculations respecting their priority. The argument of Heineken is to this effect: “It is improbable that a printer who had printed an edition wholly with moveable types should afterwards have recourse to an engraver to cut for him on blocks of wood a portion of the text for a second edition; and it is equally improbable that a wood-engraver who had discovered the art of printing with moveable types, and had used them to print the entire text of the first edition, should, to a certain extent, abandon his invention in a second by printing a portion of the text from engraved blocks of wood.” The following is the order in which he arranges the different editions: 1. The Latin edition in which part of the text is printed from wood-blocks. 2. The Latin edition in which the text is entirely printed from moveable types. 3. The Dutch edition with the text printed wholly from moveable types, supposed by Meerman to be the _first edition_ of all.[II-80] 4. The Dutch edition with the text printed wholly from moveable types, and which differs only from the preceding one in having the two pages of text under cuts No. 45 and 56 printed in a type different from the rest of the book. [Footnote II-80: Heineken seems inclined to consider this as the second Dutch edition; and he only mentions it as the first Dutch edition because it is called so by Meerman.--Idée Gén. pp. 453, 454.]
