Henry Thomas Maire Silvertop Witham (1779–1844) was an early researcher into the internal structure of fossil plants. He was a fellow of the Geological Society of London and of the Royal and Wernerian Societies of Edinburgh.〔("Mr. Watham's Observations of Fossil Vegetables" ) Sir David Brewster, ''The Edinburgh Journal of Science'' (1831) Vol.8, p.183〕 Born Henry Silvertop, he married Eliza, daughter of Thomas Witham, esq. of Headlam, in the county of Durham, and niece and heiress of William Witham, esq. of Cliffe, in Richmondshire, North Yorkshire, and thus inherited the Witham name and Coat of arms. Though having no botanical training, he applied William Nicol's method of examining fossils and rocks under the microscope by slicing them into thin sections. Nicol's first published account of this process is contained in Witham's 1831 publication, ''Observations of Fossil Vegetables''.〔Sir Archibald Geikie, ''The Founders of Geology'' (1897)〕 Witham's findings were also published in his 1833 book ''The Internal Structure of Fossil Vegetables found in the Carboniferous and Oolitic deposits of Great Britain'', illustrated by William MacGillivray. He worked strenuously for the Mechanics Institute, which provided education for the working classes and the Relief of the Sick Poor.〔http://www.teesdalediscovery.com/blue_plaque_trail.htm〕 ==See also== * ''The Birds of America'' - sale in 2010 of a copy of the book presented to Witham's wife 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Henry Witham」の詳細全文を読む スポンサード リンク
