This description of captured Portuguese, Spanish and Brazilian slave ships was written by George McHenry of Liverpool, a surgeon based on the island of St. Helena in the Atlantic. He describes the appearance of the slaves, the conditions in which they had crossed the Atlantic, the diseases usually found on board, and the processing of the captured slave ships. McHenry's account was published by the British and Foreign Anti-Slavery Society, and figures for the slave trade to Cuba were added by the editor along with the following remark: "Spain alone is responsible for the continuance of the Slave-trade. Let the public voice demand its cessation, and it will cease" (4).
