Cox & Forkum was an editorial cartoon drawn by John Cox and written by Allen Forkum.
 The comic exists primarily on the web (as a webcomic) but has also been published in newspapers, magazines, and four self-published compilations.
The Southern Aegis is a pro-Southern newspaper established in 1856 by George Yellott and John Cox and published from July 11, 1857 to February 1, 1862 in Bel Air, Maryland.
 Cox's editorial tone was overwhelmingly negative towards the Union, and he became known as an "editor of the old school, violent in his sympathies and in his editorials" with a signature "old fashioned Jacksonian style."
 However, Cox eventually realized that there was not enough support for the Confederate cause in Harford County to continue publishing, and in 1862, he sold the paper to a prominent local lawyer named A.W. Bateman, who changed the name of the paper to "The Southern Aegis, and Harford County Intelligencer".
 Bateman changed the tone of the paper to a conservative Unionist stance, which continued under his successor, Frederick W. Baker.
 Baker purchased the newspaper in 1864 and slightly changed its name to "The Aegis & Intelligencer".
 "The Aegis & Intelligencer" was sold to John D. Worthington, Sr. in 1904, but kept its name until 1923, when it was changed to The Aegis (newspaper).
L'enfant et les sortilèges: Fantaisie lyrique en deux parties ("The Child and the Spells: A Lyric Fantasy in Two Parts") is an opera in one act, with music by Maurice Ravel to a libretto by Colette.
 It is Ravel's second opera, his first being "L'heure espagnole".
 Written from 1917 to 1925, "L'enfant et les sortilèges" was first performed in Monte Carlo in 1925 under the baton of Victor de Sabata.
Jack E. Cox, BSC, know variously as J. J. Cox, Jack Cox, John J. Cox and John Cox, was an English cinematographer born in London, on 26 July 1896.
 After a prolific career of 85 films in 33 years, Cox died in Surrey on the 29 July 1960.
John Cox Cottage, at 469 Broadview Avenue, Toronto, is the oldest known house in the city still used as a residence, and it still resides on its original site.
 The property - immediately to the east of what was John Scadding's original lot - was deeded to John Cox by Governor Simcoe in 1796.
John Cox is an American screenwriter born and currently residing in Los Angeles, California.
 Cox co-wrote the film "Boot Camp" (2007), and the most current draft of Sgt. Rock for Joel Silver and Warner Bros. He also wrote "Virulents" for New Regency and director John Moore.
 Unproduced credits include "The Cold" (Warner Bros.), "The 10th Planet" (MGM), and "The Cotton Club Murder" (USA Network).
John Cox (born 12 March 1935) is an English opera director.
 Born in Bristol, he was educated at St Edmund Hall, Oxford, and trained at Glyndebourne as assistant to Carl Ebert, and then at the York Theatre Royal and BBC television, made his directing debut with Ravel's "L'enfant et les sortilèges" for the Sadler's Wells company in 1965.
The first Cox's sandpiper was recorded in Australia in 1955.
 Observers initially identified the birds as dunlins ("Calidris alpina"), but as additional birds were discovered — particularly in the period between 1968 and 1975 — doubts were cast on the initial identifications.
 By 1986, at least 20 such birds had been observed along the continent's southern and eastern coasts, though no consensus existed about their identity; among the theories postulated were that the birds were aberrant individuals or a previously undescribed subspecies of the dunlin, or that they were a stereotyped hybrid (meaning that all birds of some hybrid parentage appear near-identical).
 In order to help resolve the problem of the birds' identity John Cox collected two specimens, one in 1975 and another in 1977, and deposited them at the South Australian Museum.
 Thinking that the birds might be "Cooper's sandpipers" (see below), the two specimens were sent to the American Museum of Natural History in 1977 for comparison with the type specimen from which that form was named; replies indicated that the birds were not of the same species.
 A live bird was caught and photographed in 1981, and, in 1982, Shane Parker formally described the bird as a new species.
Rev. John Cox Edghill DD (1835–1917), known as Cox Edghill, was a British Anglican priest and military chaplain.
 He was senior chaplain at Aldershot from 1861, then followed chaplain to the forces at Chatham, Halifax (Nova Scotia), again at Aldershot, Gibraltar, and, finally, at Portsmouth (1881-5), and then Chaplain-General to Her Majesty's Forces (1885–1901).
 Following his retirement, he undertook the position of Prebendary of Wells, which he held until his death.
Michael John Cox (born 26 April 1957) is a former Australian cricketer who played several matches for Western Australia during the mid-1980s.
 Born in Newcastle, Cox grew up in New South Wales, where he attended Maitland Boys High School and captained the school's cricket team.
 Having played for local teams in Maitland and Newcastle, he was selected for several regional representative sides before moving to Sydney where he played with Gordon in the Sydney grade cricket competition.
 Although Cox played several times at colts level, he was never selected for the New South Wales state team and eventually moved to Western Australia to further his opportunities.
 His only matches at state level came during the 1985–86 and 1986–87 seasons, when Western Australia's usual wicket-keeper, Tim Zoehrer, was unavailable due to national selection.
 Cox achieved moderate success in both Sheffield Shield and McDonald's Cup matches, but was dropped when after Zoehrer's return.
