He captained Cambridge UCCE in 2009, and the Cambridge Varsity Blues side in 2009 and 2010.  His highest score of 193 came when playing for Cambridge University in the match against Oxford University Cricket Club.  His best bowling of 4/50 came in the same match. In C. S. Lewis's fantasy novel series the "Chronicles of Narnia", the hill of the Stone Table, or Aslan's How, is a high mound or cairn south of the Great River in Narnia next to the Great Woods.  The How was built over the hill of the Stone Table.  The word "how" derives from the Old Norse "haugr", meaning hill or mound.  In parts of England, it is a synonym for "barrow". Oxford University Press (OUP) is the largest university press in the world, and the second oldest after Cambridge University Press.  It is a department of the University of Oxford and is governed by a group of 15 academics appointed by the vice-chancellor known as the delegates of the press.  They are headed by the secretary to the delegates, who serves as OUP's chief executive and as its major representative on other university bodies.  Oxford University has used a similar system to oversee OUP since the 17th century. The Magdalen Ground is a cricket ground in Oxford, England.  The ground is part of Magdalen College, one of the Oxford University colleges.  The first recorded match on the ground was in 1829, when Oxford University played Cambridge University in the grounds first first-class match.  From 1829 to 1880, the ground hosted 69 first-class matches, with the final first-class match to that point coming against the Gentlemen of England.  32 years after first-class cricket had last been played at the ground, the University played the touring South Africans in what was to be the last first-class match played at the ground.

Prof. Lee is the author of ‘Constitutional Conflicts in Contemporary Malaysia’, (Oxford University Press, 1995) and the co-author of ‘The Australian Judiciary’ (Cambridge University Press, 2001) and ‘Australian Federal Constitutional Law: Commentary and Materials’ (2nd ed, Lawbook Co, 2007).  He is the co-editor of, inter alia, two volumes of essays on ‘The Constitution of Malaysia’ (Oxford University Press, 1978 and 1986), ‘Australian Constitutional Landmarks’ (Cambridge University Press, 2003), and ‘Australian Administrative Law: Fundamentals, Principles and Doctrines’ (Cambridge University Press, 2007).

At Cambridge University, Oxford University and the New College of the Humanities, undergraduates and some graduates (e.g. BCL and MJur students at Oxford University) participate in the tutorial system in addition to attending lectures and classes.  Students are taught by faculty fellows in groups of one to three on a weekly basis.  At Cambridge, these are called "supervisions" and at Oxford they are called "tutorials." One benefit of the tutorial system is that students receive direct feedback on their weekly essays or work in a small discussion setting.  The University of Buckingham also retained the weekly tutorial system when it was set up as England's first private university in the 1970s. Clive Staples Lewis (29 November 1898 – 22 November 1963) was a British novelist, poet, academic, medievalist, literary critic, essayist, lay theologian, broadcaster, lecturer, and Christian apologist.  He held academic positions at both Oxford University (Magdalen College, 1925–1954) and Cambridge University (Magdalene College, 1954–1963).  He is best known for his works of fiction, especially "The Screwtape Letters", "The Chronicles of Narnia", and "The Space Trilogy", and for his non-fiction Christian apologetics, such as "Mere Christianity", "Miracles", and "The Problem of Pain". In the United Kingdom, the privileged presses are Cambridge University Press and Oxford University Press.  They are called this because, under letters patent issued by the Crown defining their charters, only they have the right to print and publish the Book of Common Prayer and the Authorised Version of the Bible in England, Wales and Northern Ireland.  The Cambridge University Press charter from 1534 gives it the right to print "all manner of books", and Oxford University Press received a similar right when it was chartered in 1636.  In addition both presses, by virtue of a separate set of letters patent, hold the explicit right to print the Authorised Version. Hamilton lectures on music.  He was awarded a doctorate by Balliol College, Oxford, for a dissertation on the music of Liszt.  He is the author of "Liszt: Sonata in B-minor" (Cambridge University Press, 1996) and the editor of "The Cambridge Companion to Liszt" (Cambridge University Press, 2005).  His widely publicised latest book, "After the Golden Age: Romantic Pianism and Modern" "Performance" (Oxford University Press, 2008) discusses the differences between the past and the present in concert life and playing styles.  Its conclusions have stimulated extensive debate in the musical world. The University Match in a cricketing context is generally understood to refer to the annual fixture between Oxford University Cricket Club and Cambridge University Cricket Club.  From 2001, in most of their fixtures Oxford appeared as the Oxford University Centre of Cricketing Excellence (Oxford UCCE, incorporating Oxford Brookes University), and Cambridge appeared as the Cambridge University Centre of Cricketing Excellence (Cambridge UCCE, incorporating Anglia Ruskin University), but this does not apply to the University Match(es).
