FOR SALE.-PROFESSOR TENNANT'S Private Collection of Fossils, illustrative of the British Fossiliferous Deposits, the whole being stratigraphically arranged in Cabinet with Sixty Drawers, and consisting of more than 2800 species, viz. : Tertiary and comprising upwards of 8000 Specimens. 496 The Collection was originally arranged and named by the late Dr. S. P. WOODWARD, F.G.S., who also prepared a printed Catalogue of it, and many of the Specimens are figured in his Manual of Recent and Fossil Shells,' and in other scientific works. A large number of additions have recently been made to the Collection, and an Illustrated Catalogue prepared by Mr. William Davies, of the British Museum. Mr. Tennant had this Collection arranged to illustrate his Lectures on Geology and Palæontology at King's College. On receiving the appointment of Keeper of the extensive collection of Minerals belonging to the Baroness Burdett-Coutts he resigned the Geological chair, which he held from 1853 to 1869. He retains the appointment, received in 1838, of Teacher of Geological Mineralogy.

This Collection, with the Collection of Fossils above, are well adapted for illustrating fifty or sixty Lectures on MINERALOGY, GEOLOGY, and PALEONTOLOGY at a first-class Educational Establishment, or would form an instructive Geological Museum for a gentleman. Price £2000. III.-TWO CABINETS, each containing 30 drawers, with 2500 Minerals, Rocks, and Fossils. Price, One Thousand Guineas. IV.-FIRST-CLASS GEOLOGICAL COLLECTION in TWO CABINETS, each measuring 9 ft. 3 in. long, 2 ft. 4 in. wide, and 3 ft. 10 in. high; each containing 45 drawers, with a glass case on the top of each cabinet, 4 ft. 11 in. high, and 15 in. from back to front. One Cabinet is filled with 2600 Minerals and Rocks, the other with 3400 Fossils, British and Foreign, stratigraphically arranged.
