John Leyland was a British hunter and naturalist. He and Francis Nicholson* set out on a hunting trip into the Kalahari but travelled by separate routes from the Modder River to Lake Ngami, which they reached in 1851. Both collected birds along the way. Those collected by Leyland were sold to Sir William Jardine. Leyland became the second visitor to Lake Ngami, following David Livingstone*, to describe his adventure. His book, Adventures in the far interior of South Africa, including a journey to Lake Ngami and rambles in Honduras, to which is appended a short treatise on the best mode of skinning and preserving birds, animals, etc..., was published in London in 1866. A reprint was published in 1972.
