Dr James Millar (or Miller) FRSE FRCPE (1762–1827) was a Scottish physician, botanist and author.
[1] Although a good writer on scientific topics, he was deemed a poor chief editor of the Britannica, being "slow and dilatory and not well qualified".
[5] He frequently lectured on natural history and chemistry, and was one of the physicians at the Edinburgh Dispensary, where he caught a fever and died 13 July 1827.
This work related to a plan for a tunnel from Rosyth to Queensferry, also involving John Grieve.
Millar also planned and edited a more popular dictionary of arts, sciences, and literature, the Encyclopædia Edinensis, 6 vols., Edinburgh, 1827.
