Abstract

There are eleven previously unpublished letters between James Hutton and James Watt in the Doldowlod collection, which Birmingham City Archives acquires from Lord Gibson-Watt in 1994. They were written between 1774 and 1795. Very little of Hutton's other correspondence survives, so these letters add significantly to our knowledge. The earliest letters together with two letters from Hutton to George Clerk-Maxwell , describe geological tours that Hutton made through Wales, the Midlands, and the south-west of England in 1774. The correspondence after 1774 reveals Watt's expertise in geology, and also discusses meteorology, varnish making, Symington's steam engines, the first experiments with steam navigation, pneumatic medicine, and other topics
