thumb Lucas Barrett (November 14, 1837 – December 19, 1862) was an English naturalist and geologist.〔(【引用サイトリンク】accessdate=18 February 2012 )〕〔 which in turn cites the obituary by S. P. Woodward in ''Geologist'' (Feb. 1863), p. 60.〕〔death given as Dec 19 in The Reader, Volume 1, p. 124〕 Barrett was born in Canada and educated at University College School. He went to Ebersdorf, near Lobenstein, Vogtland, Germany in 1853, studying botany and chemistry for a year. In 1855, he accompanied R. McAndrew on a dredging excursion from the Shetland Islands to Norway and beyond the Arctic Circle; he subsequently made other cruises, to Greenland and to the coast of Spain. These expeditions laid the foundations of an extensive knowledge of the distribution of marine life. In 1855, he was engaged by Sedgwick to assist in the Woodwardian Museum at Cambridge. During the following three years, he aided the professor by delivering lectures. He discovered bones of birds in the Cambridge Greensand, and he prepared a geological map of Cambridge on the one-inch Ordnance map. In 1859, when he was twenty-two, he was appointed director of the Geological Survey of Jamaica. There, he determined the Cretaceous age of certain rocks that contained Hippurites. S. P. Woodward named the new genus ''Barrettia'' after him. Barrett also collected many fossils from the Miocene and newer strata. He drowned, at the early age of twenty-five, while investigating the sea-bottom off Kingston, Jamaica. ==References== 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「Lucas Barrett」の詳細全文を読む スポンサード リンク
