Geology. 319 



Power (EDWARD) 



Presented the W. C. Lucy Collection of English fossils, 1895. 



Powrie (JAMES) 



Presented fossil Fishes and a nearly complete body of Pterygotus 

 anglicus from the Lower Old Red Sandstone of Forfarshire, 1861, 1865, 

 His large collection from the same formation and locality was purchased 

 later by the Edinburgh Museum of Science and Art. 



Pratt (SAMUEL PEACE) [1789-1863] 



An enthusiastic student of many sciences, Pratt finally turned to 

 geology in 1812, and during the rest of his long life collected many 

 valuable specimens, with which he was most generous. In 1823 he went 

 to Bath, where he resided for sixteen years, and this renders it probable 

 that he was the donor, on March 8th, 1828, of " An undescribed crinoidal 

 animal imbedded in Limestone from Bath," although J. E. Gray, who- 

 described it as Apiocrinites prattii (Phil. Mag., 1828), referred to him. 

 as Mr. J. S. Pratt. At any rate, two years later, S. P. Pratt was a donor 

 to the Natural History Departments of the Museum. His first work was 

 on the freshwater formation at Binsted, Isle of Wight, where he discovered 

 Anoplotherium and Paleeotherium (Trans. Geol. Soc,, 1831). After this 

 he travelled much on the continent, studying and writing on bone-caves- 

 near Palermo (1833), on the geology of Normandy (1837), of Bayonne 

 (1843), of the Astuiias (1845), and of Catalonia (1852). Pratt made 

 numerous donations to the Geological Department, e.g., in 1846, some 

 remarkable Tertiary fossils including the gregarious cyprinodont fish 

 Lebias cephalotes from Aix in Provence; in 1850 and 1851, various 

 fossils from the Mesozoic formations of southern England and a series of 

 Rudistas and allied forms from the Chalk near Toulon ; in 1854, a further 

 series of those curious molluscs, some of which were figured by S. P. 

 Woodward (Quart. Journ. Geol. Soc., 1855) ; in 1852 nummulites, crinoids, 

 and other invertebrates, from the Eocene of Biarritz, Nice, Barcelona, etc., 

 among which the type of Pentacrinus pratti, Austin, is noteworthy; 

 in 1853, brachiopods and other invertebrates from Asturias, the latter 

 yielding specimens subsequently figured by Etheridge and Carpenter 

 (" Catalogue of Blastoidea," 1886). Finally, in 1857, Pratt presented about 

 1000 selected specimens of invertebrates, chiefly from British Mesozoic 

 rocks. Many of his specimens were placed in the Museum of the 

 Geological Society, others in the Museum of Practical Geology, the 

 foreign specimens among the latter being transferred to the British 

 Museum in 1880. 



Prestwich (Sir JOSEPH) [1812-1896] 



During his long series of researches, Prestwich accumulated a large 

 collection illustrating his work, and this was acquired by the British 

 Museum in three instalments. The first, comprising 1755 specimens- 

 chiefly of British Eocene invertebrates and plants, was presented by the 

 Professor in 1885. The second portion contained 1314 Carboniferous and 

 Silurian fossils from Coalbrookdale, referred to in his memoir on the 

 district (Trans. Geol. Soc., 1840), also a few Vertebrata from the Crag, 

 and some Pleistocene mammalian bones from Bedford ; it was purchased 

 in 1894, and was accompanied by a MS. catalogue by Prof. T. Rupert 

 Jones. The third more miscellaneous portion, including some Palaeolithic 

 Implements and the Eolithic Implements from Kent described in " Some 

 Controverted Questions of Geology," was presented by Lady Prestwich in
