There is a story somewhere of an Englishman, a Frenchman, and a German being each called on to describe a camel. The Englishman immediately embarked for Egypt, the Frenchman went to the Jardin des Plantes, and the German shut himself up in his study and thought it out!
-Joseph Dalton Hooker (1817-1911), Middle East explorer and botanist
Hooker was said to have been Charles Darwin’s closest friend so presumably he knew a bit about the taxonomy of camels. But even if he had visited Egypt, which he never did, could Hooker have outdone KhairAllah when he shouted at a particularly recalcitrant one, Yā Himār, O Donkey!
