In 1821 Ure published his first major book,
Dictionary of Chemistry, a replacement for
William Nicholson's outdated dictionary. It came out two years after
William Brande's
Manual of Chemistry, and Ure was accused of plagiarism. Subsequently, Ure accused
William Henry and
Thomas Thomson of plagiarism of his own works. In 1822, he was elected a
Fellow of the Royal Society. By 1830, Ure's outside interests led him to resign first from his chair and then from the institution. He moved to London and set himself up as a consulting chemist (probably the first such in Britain). His work included acting as an
expert witness, taking on government commissions, and making industrial tours of England, Belgium, and France. His visits to English
textile mills led to his 1835 publication of
The Philosophy of Manufactures; followed by
An Account of the Cotton Industry in 1836; both dealing with the
textile industry conditions. In 1840, he helped found the
Pharmaceutical Society of Great Britain. His exposure to factory conditions led him to consider methods of heating and ventilation for workers, and he is credited with being the first to describe a bi-metallic
thermostat. The
Dictionary of Arts, Manufactures and Mines, Ure's chief and most encyclopaedic work, was published in 1837. Enlarged editions were rapidly called for in 1840, 1843, and 1853. After his death, four further editions appeared—the last in 1878. This work was translated into almost every European language, including Russian and Spanish.
The Times review said: "This is a book of vast research, and the variety of subjects embraced in it may be estimated by the fact that on the French translation it was thought advisable to employ nineteen collaborators, all regarded as experts in their special subjects." Historical accounts of the advancement of geology regularly make mention of Ure. ==Geology==
