Question: How long had the HMS St Jean d'Acre existed prior to when Prince Victor of Hohenlohe-Langenburg served on it? Passage:Victor (sometimes spelled Viktor) became an officer in the Royal Navy in 1848 and was promoted to Lieutenant in 1854. As a Lieutenant, he served on the first-rate HMS St Jean d'Acre in the Mediterranean under Captain Henry Keppel in 1855; commanded the gunboat HMS Traveller for a few months in 1856 after her launch until she was paid off; served again under Keppel again on the fourth-rate HMS Raleigh in the East Indies and China, until she was wrecked near Macau in 1857. He was recommended for the Victoria Cross for his service in China in 1856. He was promoted to Commander in 1857, and commanded the first-rate sloop HMS Scourge in the Mediterranean. Promoted to Captain in 1859, he took command of the 21-gun corvette HMS Racoon from commissioning in 1863 until 1866, during which time Queen Victoria's second son, Alfred, Duke of Edinburgh (1844–1900) served on board as a lieutenant.

Question: How long had Prüm Abbey existed when Eygilo left to become the abbot of Flavigny? Passage:The fame of Flavigny was due partly to the relics which it preserved, and partly to the piety of its monks. The monastery was at the height of its reputation in the eighth century, in the time of the Abbot Manasses, who was appointed by Pippin the Short. In 760/62, Manasses attended the council of Attigny. Pippin's successor, Charlemagne, authorized Manasses to found the Carolingian style monastery of Corbigny. The same Manasses transferred from Volvic to Flavigny the relics of Saint Praejectus. Abbot Apollinaris, appointed by Charlemagne in 802, was also abbot of Saint-Bénigne de Dijon and Môutier-Saint-Jean. Charlemagne's son, Louis the Pious, used Abbot Adrevaldus as an envoy to Septimania in 834 and 838, according to the Historia Hludowici imperatoris. However, these dates do not correspond to those given in the abbey's only list, which says that Adrevaldus became abbot in 839 and ruled for three years. Eygilo, the founder of Prüm Abbey, left his own establishment to become abbot of Flavigny in 860. He set up monks at Corbigny, but later left Flavigny when he was appointed Archbishop of Sens. His successor, Geylo, resigned to become abbot of Tournus and was later appointed bishop of Langres.

Question: How many people are buried in the same place Charles is? Passage:Lyell's wife died in 1873, and two years later (in 1875) Lyell himself died as he was revising the twelfth edition of Principles. He is buried in Westminster Abbey. Lyell was knighted (Kt) in 1848, and later, in 1864, made a baronet (Bt), which is an hereditary honour. He was awarded the Copley Medal of the Royal Society in 1858 and the Wollaston Medal of the Geological Society in 1866. Mount Lyell, the highest peak in Yosemite National Park, is named after him; the crater Lyell on the Moon and a crater on Mars were named in his honour; Mount Lyell in western Tasmania, Australia, located in a profitable mining area, bears Lyell's name; and the Lyell Range in north-west Western Australia is named after him as well. In Southwest Nelson in the South Island of New Zealand, the Lyell Range, Lyell River and the gold mining town of Lyell (now only a camping site) were all named after Lyell. The jawless fish Cephalaspis lyelli, from the Old Red Sandstone of southern Scotland, was named by Louis Agassiz in honour of Lyell.
