Cornwall during the time of the Celts was a part of the Brythonic area of Britain, separated from Wales after the Battle of Deorham. The Kingdom of Cornwall often came into conflict with the expanding Saxon kingdom of Wessex, before the boundary between English and Cornish people was set at the Tamar. The Cornish language continued to be spoken until the 18th century, although a recent revival has seen the number of Cornish speakers increasing over the past few decades.
Clotted cream is a thick yellow cream made by heating and then leaving unpasteurized cow's milk in shallow pans for several hours. During this time, the cream content rises to the surface into 'clots'. Clotted cream is a Cornish speciality and in the European Union, Cornish clotted cream is a protected designation of origin for cream produced by the traditional recipe in Cornwall. True Cornish clotted cream must be made from unpasteurised milk or the clots will not form and has a minimum fat content of 55%.
The son of a Truro innkeeper, Lander's explorations began as an assistant to the Scottish explorer Hugh Clapperton on an expedition to western Africa in 1825. After returning to Britain in 1828, he went to western Africa again in 1830, accompanied by his brother John. They landed at Badagri on 22 March 1830 and followed the lower Niger River from Bussa to the sea. After exploring about 160 kilometres of the Niger River upstream, they returned to explore the Benue River and Niger Delta. They travelled back to Britain in 1831.
In 1832, Lander returned again to Africa as leader of an expedition organized by Macgregor Laird and other Liverpudlian merchants, with the intention of founding a trading settlement at the junction of the Niger and Benue rivers. However, the expedition encountered difficulties, many personnel died from fever and it failed to reach Bussa. While journeying upstream in a canoe, Lander was attacked by African tribesmen and wounded by a musket ball in his thigh. He managed to return to the coast, but died there from his injuries.
