' In the controversy respecting the priority of Watt or of Henry Cavendish in the discovery of the composition of water, 

 Muirhead took infinite pains to silt every particle of evidence. Not satisfied with free access to the Watt and Boulton 

 papers, and to such living authorities as Brewster, Davy, Jeffrey, and Brougham, he visited Paris in 1842 to confer with 

 Arago, Berzelius, and other savants, and in 1846 published a clear vindication of Watt's rights'. D. N. B.

 of James Watt' (q. v. supra). D. N. B.

 Watt, and of the inventions of Watt himself, is contained in Muirhead a Mechanical Inventions of James Watt, and Life of 

 James Watt; works specially distinguished by the fullness and precision with which original documents and authorities
