Geology. 283 



" Geology of Weymouth and the Isle of Portland " (Ed. 2, 1884), in the 

 Supplement to which nearly half of the specimens were figured. The 

 collection was purchased by the British Museum from Mr. Damon's 

 executor in 1890. 



Davidson (THOMAS) [1817-1885] 



Born at Muir House, Midlothian, Davidson spent much of his youth 

 on the continent of Europe, in the study of both art and science. While 

 in Rome, at the age of twenty, he was attracted by Leopold v. Buch to 

 the study of the Brachiopoda, and to this group he devoted the rest of his 

 life, gathering at his Brighton residence a large collection of both recent 

 and fossil forms, and writing numerous papers, which were illustrated by 

 his own crayon. His magnum opus was the "Monograph of British 

 Fossil Brachiopoda" published by the Palseontographical Society 

 (1850-1886), but he also wrote on the brachiopods of other countries 

 from France to China, and published through the Linnean Society a 

 monograph of Recent Brachiopoda. The first of many donations to the 

 British Museum was made by him in 1848, and his entire collection of 

 specimens, drawings, and illustrative books and pamphlets, bequeathed by 

 him to the Trustees, was handed over by his son, Mr. Wm. Davidson, in 

 1886. It comprises 1796 named species and 22,831 specimens, which, by 

 the direction of the testator, are kept apart in one series. To it, however, 

 have in better accordance with the spirit of his will, been joined various 

 specimens described by him and previously presented. The specimens 

 are all accompanied by Davidson's own carefully-written MS. labels. 



Davies (GEIPPITH) 



Collected Ordovician Trilobites from North Wales, purchased 1871. 

 Davis (JAMES WILLIAM) [1846-1893] 



Resident at Chevinedge, Halifax, Davis was much interested in fossil 

 fishes and in the geology of Yorkshire, on which subjects he published 

 several papers. His collection of fossils consisted chiefly of fish-remains 

 from the Yorkshire Coal-Measures and the Dorsetshire Lower Lias, with 

 a few others from Carboniferous, Rhsetic, Cretaceous, and Tertiary rocks. 

 They included many specimens, especially those from the Coal-Measures 

 and Lias, described in his own papers. A selection of 324 specimens 

 from this collection was purchased by the Museum from his executor 

 in 1895. 



Dawkins (WILLIAM BOYD) 



Collected and presented Mammalian remains from Windy Knoll and 

 Creswell Caves, Derbyshire, 1885. 



Dawson (CHARLES) 



Mr. Dawson, residing formerly at Hastings, now at Uckfield, collected 

 the remains of Dinosauria and other Reptilia from the Wealden near 

 Hastings. His first collection was purchased by the Museum in 1884, 

 and further small instalments were added in the years 1885, 1887, 1888, 

 1892, and 1894. The bones of Iguanodon are especially noteworthy, and 

 include the type-specimens of 1. dawsoni, 1. fittoni, and /. holling- 

 toniensis, described by Mr. Lydekker in the Geological Magazine 

 (1889). 

 Dawson (Sir JOHN WILLIAM) 



This well-known Canadian geologist presented a few specimens illus- 

 trating his researches, namely, land-shells and small land-reptiles from.
