What subjects did Sir Richard Burton write about after his travels in West Africa?

Following his tenure as a consul in Fernando Po, where he conducted various explorations into West Africa, Sir Richard Burton authored five books detailing his observations of the region.1

His writings focused on explicit descriptions of local customs and social practices, including:

• Tribal rituals surrounding birth, marriage, and death.1
• Practices related to fetishism.1
• Accounts of ritual murder and cannibalism.1
• Descriptions of what he termed bizarre sexual practices.1

While these detailed ethnographic accounts are now appreciated by modern anthropologists for their descriptive value, they were poorly received by the British Foreign Office at the time, which viewed Burton's work and interests as eccentric or potentially dangerous.1
