James Sprent Virtue (1829-1892) purchased the Rudimentary Series of engineering and scientific publications from Thomas Tredgold's publisher John Weale some time in the 1850s. It appears that he also took over the publication rights to Tredgold's Steam Engine. Marine Engines and Boilers is not a straightforward reprint of the second division of Weale's 1850-53 edition; instead, it comprises essays and plates from both the second and third divisions. It also includes a glossary of terms in Spanish and French, indicating the international nature of engineering research in this era.
Tredgold (1788-1829) was a self-taught engineer and widely read technical author who also published on timber and carpentry, cast iron, railroads and carriages, and heating and ventilation. Several of his works became "the standard textbooks of English engineers" (ODNB). His final work The Steam Engine (1827) was a "notable contribution to steam engine design and theory" (James K. Finch, Engineering Classics, p.110). Architectual publisher John Weale published significantly expanded second and third editions in 1838 and in 1850. Tredgold may be best remembered for his definition of engineering, used by the Institute of Civil Engineers in its 1828 application for a royal charter: "the art of directing the great sources of power in nature for the use and convenience of man" (Miller, "The Classics of Engineering Literature," College English 19:2, 1957).
