Philadelphia physician Samuel George Morton helped shape the development of physical anthropology in antebellum America. His diary of a trip to the West Indies offers a case study in scientific racism. The volume includes various observations on life, work, agriculture, and slavery in Barbados and other islands. Notably, Morton's journal includes derogatory comments on the native inhabitants that researchers might choose to examine in tandem with other records available in the Samuel George Morton Papers, such his "craniometrical drawings," which were used by pro-slavery advocates. This diary may interest scholars examining slavery in antebellum science and racial thought, slavery in Barbados, and the history of the West Indies more broadly.
