Editing Lexicon Technicum (section)

== Overview ==
The ''Lexicon Technicum'' was the work of a London clergyman, [[John Harris (writer)|John Harris]] (1666-1719). Its professed advantage over [[French language|French]] dictionaries of the arts and sciences was that it contained explanation not only of the terms used in the arts and sciences, but also of the arts and sciences themselves. Harris issued a three-page proposal for this work in 1702, and the first edition of the first volume was published in London in 1704. The first volume contains 1220 pages, 4 plates, and many additional diagrams and figures within the text. Like many early English encyclopedias, the pages are not [[Page numbering|numbered]]; numbering may have been thought unnecessary as readers could search by its [[alphabetical]] arrangement.

Volume 2, which was also alphabetized from A through Z, was first published in 1710. The second volume contains 1419 pages and 4 plates, with a list of about 1300 subscribers. A previously unpublished treatise on [[acids]] by [[Sir Isaac Newton]] was included in its original [[Latin]]<ref>"De Natura acidorum" (1692)</ref> along with Harris's English translation,<ref>"Some Thoughts about the Nature of Acids; by Sir Isaac Newton"</ref> perhaps without the latter's permission or encouragement.<ref>[[Lael Bradshaw|Lael Ely Bradshaw]], “John Harris’s ''Lexicon Technicum'',” in ''Notable Encyclopedias of the Seventeenth and Eighteenth Centuries: Nine Predecessors of the Encyclopédie'', ed. [[Frank Kafker|Frank A. Kafker]] ([[Oxford]]: [[Voltaire Foundation]], 1981), p.110.</ref> A large part of the volume consists of mathematical and [[astronomical]] tables, since Harris intended his work to serve as a small mathematical library. He provided tables of [[logarithms]], [[sines]], [[tangents]], and [[secant (trigonometry)|secants]], a two-page list of books, and an index of the articles in both volumes under 26 heads, filling 50 pages. The longest lists are for law (1700 articles), [[surgery]], [[anatomy]], [[geometry]], [[fortification]], [[botany]], and music.

In his preface, Harris stated that he got less help from previous dictionaries than one would expect. While acknowledging some borrowing, Harris insisted that "much the greater part of what [the reader] will find here is collected from no Dictionaries, but from the best Original Authors I could procure." Harris's preface touted his coverage of mathematical subjects. He admitted the imperfection of his data on [[stars]], noting that [[Flamsteed]] had refused to assist him, but he vaunted his coverage of astronomy, especially his full coverage of Newton's theories of the [[moon]] and of [[comets]]. In botany he claimed to have given "a pretty exact botanick lexicon, which was what we really wanted before," using [[John Ray|Dr John Ray]]'s method. To describe the parts of a [[ship]] accurately, he supposedly "often" went on board himself. In law, he wrote, he abridged from the best writers and had the result "carefully examined and corrected by a Gentleman of known Ability in that Profession."

The specified aims of the book did not prevent Harris from including some highly opinionated asides, for example this definition conveying the poor view he took of [[lawyers]]:  "Sollicitor, is a Man imploy'd to take care of, and follow Suits depending in Courts of Law, or Equity, formerly allowed only to Nobility, whose Menial Servants they were; but now too frequently used by others, to the damage of the People, and the increase of [[Champerty and maintenance|Champerty and Maintenance]]".

Harris wrote that he had wished to supply an index for each art and science as well as more plates on anatomy and ships, but the underwriters could not afford it, "the Book having swelled so very much beyond the Expectation."

A review of this work, extending to the unusual length of four pages, appeared in the ''[[Philosophical Transactions]]'' for 1704.<ref>{{cite journal |last1=Harris |first1=J. |title=An Account of a Book: Lexicon Technicum; [...] |journal=Philosophical Transactions of the Royal Society of London |date=July 1704 |volume=24 |issue=292 |page=1699 |url=https://www.biodiversitylibrary.org/page/47753651#page/223/mode/1up}}</ref>

The ''Lexicon Technicum'' was long very popular, enduring through at least 1744 as the main rival of [[Ephraim Chambers]]'s ''[[Cyclopædia, or an Universal Dictionary of Arts and Sciences|Cyclopaedia]]''. The final publication of the two volumes of the ''Lexicum Technicum'' was in 1736. An anonymous one-volume supplement did appear in 1744, with 996 pages and 6 plates, but this work was allegedly "not well received," being perceived by contemporaries as a mere "booksellers speculation."<ref>"Encyclopaedia," in ''[[Encyclopædia Britannica]]'', 13th edition, vol. 19, p. 373.</ref> In any case, no new editions of the ''Lexicon Technicum'' were published thereafter.
