Question: How old was John Hamilton, 1st Marquess of Abercorn, when his younger son was elected to Parliament? Passage 1:The younger son of John Hamilton, 1st Marquess of Abercorn, he was evidently educated at Harrow School, where he was a lieutenant of volunteers in 1803. He matriculated at Christ Church, Oxford on 24 October 1805, but left there for Cambridge, where he was admitted as a nobleman to St John's College on 19 October 1807. In the mean time, he was elected as Member of Parliament for Dungannon at the general election in May 1807, though underage, through the patronage of his father's political ally, Thomas Knox, 1st Viscount Northland. It was intended that he should later contest County Donegal or County Tyrone, but he suffered from illness, and may not ever have taken his seat. In January 1808, he sailed for Brazil in the brig Eclipse to recover his health, but died in Madeira in June.
 Passage 2:Specimens of Lambertia formosa were collected by botanists Joseph Banks and Daniel Solander during Lieutenant James Cook's landing at Botany Bay between April and May in 1770. These are thought to have been obtained from vegetation currently known as the Eastern Suburbs Banksia Scrub that occurs in sandy areas near present-day La Perouse. The shrub was first described in 1798 by English botanist James Edward Smith who concurrently erected the new genus Lambertia, the name honouring English botanist Aylmer Bourke Lambert. The specific name formosa is the Latin adjective for 'handsome'. English plantsman Henry Charles Andrews wrote in 1799, "Of all the plants yet introduced from New Holland, that have hitherto flowered with us, this unquestionably takes the lead for beauty, considering the plant altogether", although his countryman Joseph Knight in his 1809 work On the cultivation of the plants belonging to the natural order of Proteeae added that the species name "applies only to the flowers, the foliage being generally of a sickly hue". French botanist Michel Gandoger described specimens collected at Hornsby and Port Jackson as Lambertia proxima, and material sent to him by plant collector Charles Walter as L. barbata in 1919; these turned out to be L. formosa. Gandoger described 212 taxa of Australian plants, almost all of which turned out to be species already described.
 Passage 3:Ogston was the son of Alexander Milne Ogston of Ardoe, Kincardineshire. He was educated at the Royal Military College, Sandhurst and commissioned a second lieutenant in the Gordon Highlanders in November 1897. He served on the North-West Frontier of India from 1897 to 1898 and took part in the Tirah Campaign under Sir William Lockhart. Promoted to lieutenant on 21 July 1899, he was later the same year sent to South Africa to serve as an intelligence officer in the Second Boer War. He took part in the Relief of Kimberley (February 1900), including the Battle of Magersfontein (11 December 1899), followed by fighting in the Orange Free State from February to May 1900, including the Battle of Paardeberg (18–27 February 1900). In May 1900 he was posted to the Transvaal Republic, where he took part in the occupation of Johannesburg and Pretoria, the capital of the republic, followed by service around the occupied areas, including the Battle of Bergendal (August 1900) and fighting near Lydenburg. He was promoted to captain on 22 January 1902, and following the end of hostilities in early June 1902 left Cape Town on board the SS Orotava, arriving at Southampton the next month.
