(497th MEETING) SATURDAY, I5TH FEBRUARY 1919. Some 40 Members assembled at the Linnean Society's Rooms at 2.30 o'clock in the afternoon, and were received by Dr. B. Daydon Jackson, General Secretary of the Society, who had very kindly consented to exhibit and to give an account of Linnaeus's Collections, Herbarium, and Library. The Linnean Society of London takes its name, of course, from the great Swedish naturalist, Carl Linnaeus (1707-1778), ennobled as Carl von Linne in 1761. On the death of the younger Linne in 1783, his mother and sole executrix offered the whole of the Linnean collections to Sir Joseph Banks, who declined to purchase, but advised Mr. James Edward Smith (1759-1828), a young Norwich doctor, then settled in London, to do so. Smith agreed, and the collections and books arrived in London in 1784. Returning in 1787 from a tour abroad, during which he took his degree of M.D. at Leyden, Smith resolved to establish a Society under the name of the great Swedish naturalist. A meeting was called for 26th February
