This account by F. Torres Texugo, a Portuguese political exile in Britain, describes the continuing slave trade from the East coast of Africa to Brazil in the late 1830s. Texugo describes his writing as a faithful first hand account, and offers it to the British abolitionists as a useful source of information on the Portuguese slave trade at Mozambique. The letter is addressed to Thomas Fowell Buxton, the founder of the Society for the Extinction of the Slave Trade and the Civilisation of Africa.
