(1773-1835), geologist, mineralogist, chemist, and physician, member of a good Scotch family of Cardoness, Kirkcudbrightshire, was born in Guernsey, taught at Plympton, Penzance, and Lostwithiel; studied medicine in Edinburgh, and gained his diploma in 1791. In 1795 he became assistant-surgeon in the Artillery, and in 1803 he was appointed chemist to the Ordnance. From 1807 to 1811 he practised as physician at Blackheath, after which he was employed until 1832 in various mineralogical and geological surveys of Scotland. He then became lecturer in chemistry and geology in the East India Company's military college at Addiscombe. He died in consequence of a carriage accident very soon after his marriage. Dr. McCulloch published four large geological works, two medical works, and a Treatise on the Art of Making Wines (1821).
