This collection contains diaries, weather records, and commonplace books of Thomas Thistlewood for the years 1748-1786. His diaries (37 volumes) cover two years in England (in London and in Lincolnshire) and the remaining time in Jamaica (1750-1786). This is a rich source for agricultural, daily routines, slave life, folklore, natural history, medical diagnosis and remedies, the intellectural world of an Anglo-Jamaican, his sex life, and the climatic history of Jamaica. There are also miscellaneous volumes, such as a list of slaves, 1758-1766. Included in the collection is the journal of his nephew, John Thistlewood, 1763-1765, describing his voyage to Jamaica and life on his uncle's plantation.
