Question: In 1857 John Sheepshanks donated 233 paintings, mainly by contemporary British artists, and a similar number of drawings to the museum with the intention of forming a 'A National Gallery of British Art', a role since taken on by Tate Britain; artists represented are William Blake, James Barry, Henry Fuseli, Sir Edwin Henry Landseer, Sir David Wilkie, William Mulready, William Powell Frith, Millais and Hippolyte Delaroche. Although some of Constable's works came to the museum with the Sheepshanks bequest, the majority of the artist's works were donated by his daughter Isabel in 1888, including the large number of sketches in oil, the most significant being the 1821 full size oil sketch for The Hay Wain. Other artists with works in the collection include: Bernardino Fungai, Marcus Gheeraerts the Younger, Domenico di Pace Beccafumi, Fioravante Ferramola, Jan Brueghel the Elder, Anthony van Dyck, Ludovico Carracci, Antonio Verrio, Giovanni Battista Tiepolo, Domenico Tiepolo, Canaletto, Francis Hayman, Pompeo Batoni, Benjamin West, Paul Sandby, Richard Wilson, William Etty, Henry Fuseli, Sir Thomas Lawrence, James Barry, Francis Danby, Richard Parkes Bonington and Alphonse Legros.

Answer: In which year did John Sheepshanks donated a large collection of paintings?


Question: Paleoclimatologists measure the ratio of oxygen-18 and oxygen-16 in the shells and skeletons of marine organisms to determine what the climate was like millions of years ago (see oxygen isotope ratio cycle). Seawater molecules that contain the lighter isotope, oxygen-16, evaporate at a slightly faster rate than water molecules containing the 12% heavier oxygen-18; this disparity increases at lower temperatures. During periods of lower global temperatures, snow and rain from that evaporated water tends to be higher in oxygen-16, and the seawater left behind tends to be higher in oxygen-18. Marine organisms then incorporate more oxygen-18 into their skeletons and shells than they would in a warmer climate. Paleoclimatologists also directly measure this ratio in the water molecules of ice core samples that are up to several hundreds of thousands of years old.

Answer: What group of scientists seek to measure the amounts of oxygen in marine animals?
