Buddle gave Sloane thirteen volumes of British plants. In 1716, Sloane purchased Englebert Kaempfer's volume of Japanese plants and James Petiver's virtual museum of approximately one hundred volumes of plants from Europe, North America, Africa, the Near East, India, and the Orient. Mark Catesby gave him plants from North America and the West Indies from an expedition funded by Sloane. Philip Miller gave him twelve volumes of plants grown from the Chelsea Physic Garden. Sloane acquired approximately three hundred and fifty artificial curiosities from North American Indians, Eskimos, South America, the Lapland, Siberia, East Indies, and the West Indies, including nine items from Jamaica. "These ethnological artifacts were important because they established a field of collection for the British Museum that was to increase greatly with the explorations of Captain James Cook in Oceania and Australia and the rapid expansion of the British Empire." Upon his death in 1753, Sloane bequeathed his sizable collection of 337 volumes to England for £20,000. In 1759, George II's royal library was added to Sloane's collection to form the foundation of the British Museum. John Tradescant the elder (circa 1570s–1638) was a gardener, naturalist, and botanist in the employ of the Duke of Buckingham. He collected plants, bulbs, flowers, vines, berries, and fruit trees from Russia, the Levant, Algiers, France, Bermuda, the Caribbean, and the East Indies. His son, John Tradescant the younger (1608–1662) traveled to Virginia in 1637 and collected flowers, plants, shells, an Indian deerskin mantle believed to have belonged to Powhatan, father of Pocahontas. Father and son, in addition to botanical specimens, collected zoological (e.g., the dodo from Mauritius, the upper jaw of a walrus, and armadillos), artificial curiosities (e.g., wampum belts, portraits, lathe turned ivory, weapons, costumes, Oriental footwear and carved alabaster panels) and rarities (e.g., a mermaid's hand, a dragon's egg, two feathers of a phoenix's tail, a piece of the True Cross, and a vial of blood that rained in the Isle of Wight). By the 1630s, the Tradescants displayed their eclectic collection at their residence in South Lambeth. Tradescant's Ark, as it came to be known, was the earliest major cabinet of curiosity in England and open to the public for a small entrance fee. Elias Ashmole (1617–1692) was a lawyer, chemist, antiquarian, Freemason, and a member of the Royal Society with a keen interest in astrology, alchemy, and botany. Ashmole was also a neighbor of the
