The term baroque horse describes a group of horse breeds, usually descended from and retaining the distinctive characteristics of a particular type of horse that rose to prominence in Europe during the Baroque era, after significant development throughout the Middle Ages.
 It describes the type of agile but strong-bodied descendants of horses in the Middle Ages such as the destrier.
 Specific ancestors of this type include the Neapolitan horse, and the Iberian horse of Barb ancestry known in the Middle Ages as the Spanish Jennet.
 They are characterized by powerful hindquarters, a muscular, arched neck, a straight or slightly convex profile, and usually a full, thick mane and tail.
 These horses are particularly well suited for the "haute ecole" discipline of classical dressage.
A Horse's Neck is an American cocktail recognised by the IBA, identifiably sporting a long, curling strip of lemon rind.
Edward Gilbert Abbott (1825–1855) was the patient upon whom William T. G. Morton first publicly demonstrated the use of ether as a surgical anesthetic.
 The operation was done in an amphitheater at the Massachusetts General Hospital now known as the Ether Dome on 16 October 1846.
 After Morton administered the ether, surgeon John Collins Warren removed a portion of a tumor from Abbott's neck.
 After Warren had finished, and Abbott regained consciousness, Warren asked the patient how he felt.
 Reportedly, Abbott said, "Feels as if my neck's been scratched."
 Warren then turned to his medical audience and uttered "Gentlemen, this is no Humbug."
 This was presumably a reference to the unsuccessful demonstration of nitrous oxide anesthesia by Horace Wells in the same theater the previous year, which was ended by cries of "Humbug!"
 after the patient groaned with pain.
The Collins–Valentine line, or Valentine–Collins line, is the boundary at approximately 45 degrees north latitude that separates the province of Quebec from the states of New York and Vermont.
 It was surveyed and marked by survey monuments in 1771–3 by John Collins, surveyor-general of Quebec, and Thomas Valentine, a commissioner appointed by the government of New York.
Thomas Joseph "Tom" Collins (6 April 1884 – 15 April 1945) was an Australian politician and stock and station agent, born at Yass, New South Wales to storekeeper John Collins and Mary, née Hartigan.
 In 1902, having attended the local Catholic school, he enlisted in the 5th Battalion, Australian Commonwealth Horse, to fight in the Boer War.
 However, by the time Collins's unit arrived, the war had finished.
The Ether Dome is a surgical operating amphitheater in the Bulfinch Building at Massachusetts General Hospital in Boston.
 It served as the hospital's operating room from its opening in 1821 until 1867.
 It was the site of the first public demonstration of the use of inhaled ether as a surgical anesthetic on October 16, 1846, otherwise known as Ether Day.
 Crawford Long, a surgeon in Georgia, had previously administered sulfuric ether in 1842, but this went unpublished until 1849.
 The Ether Dome event occurred when William Thomas Green Morton, a local dentist, used ether to anesthetize Edward Gilbert Abbott.
 John Collins Warren, the first dean of Harvard Medical School, then painlessly removed part of a tumor from Abbott's neck.
 After Warren had finished, and Abbott regained consciousness, Warren asked the patient how he felt.
 Reportedly, Abbott said, "Feels as if my neck's been scratched".
 Warren then turned to his medical audience and uttered "Gentlemen, this is no Humbug".
 This was presumably a reference to the unsuccessful demonstration of nitrous oxide anesthesia by Horace Wells in the same theater the previous year, which was ended by cries of "Humbug!"

The Defiants were a Minnesota based garage rock band in the 1960s.
 The Defiants were formed in Clara City, Minnesota by Steve Henslin, Doug Gerken, Donny "Mixer" Mickels and Dewayne "Smitty" Smith.
 Steve Henslin later left and Mike Shaw (bass and vocals) took over leadership of the band.
 Mike brought in his brother Terry R. Shaw on drums and vocals.
 The band consisted of the Shaw brothers, Loren "Wally" Walsted on lead guitar (who died from a heart attack on Sept. 3.
 2014), and John Collins on rhythm guitar.
 This form of the group stayed together from 1963 to 1967 and recorded one single; a cover of Bob Dylan's "Maggie's Farm" backed with a cover of "Bye Bye Johnny."
 The Defiants broke up in 1967 when John Collins was drafted for service in the Vietnam War but opted to join the Marines instead.
 Mike Shaw and Terry R. Shaw later formed the group Shaw-Allen-Shaw with Jim Allen.
 That group recorded two albums, set many ballroom attendance records and, in 2006, was inducted into the Mid-America Music Hall of Fame (formerly the Minnesota Rock/Country Hall of Fame).
 Terry R. Shaw is the author of two books about growing up in the '50 in a small town (Litchfield, Minnesota).
 The books are called "Terry Tales" and "Terry Tales 2".
 In addition he has written three books about Buddy Holly, the Beatles and Elvis Presley, which can be viewed online for free.
 Shaw has also written several songs, the videos of which can be seen on www.youtube.com.

John Collins (born 27 April 1970) is the mainstay bass guitarist for Australian rock band Powderfinger since 1989.
 He is one of the founding members of the band, along with guitarist Ian Haug, forming at their high school, Brisbane Grammar School as a three piece.
 Powderfinger has released seven studio albums, a greatest hits album and a double CD live album.

 During the hiatus, Collins played with fellow Powderfinger member, Darren Middleton in his new band Drag on a number of occasions, as well as performing with Ian Haug and Steven Bishop in The Predators.
 Collins is often referred to as "J.C." by his fellow band members, as they are his initials and to distinguish him from the group's drummer Jon Coghill.
 Initially, the nickname was given to him following the group's song "JC" from their second album, "Double Allergic", which referred to Jesus Christ.
A John Collins is a cocktail which was attested to in 1869, but may be older.
 It is believed to have originated with a headwaiter of that name who worked at Limmer's Old House in Conduit Street in Mayfair, which was a popular London hotel and coffee house around 1790–1817.
