Birds (class Aves) are a group of endothermic vertebrates, characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds.
The fossil record indicates that birds are the last surviving dinosaurs, having evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago, and the last common ancestor is estimated to have lived about 95 million years ago. DNA-based evidence finds that birds radiated extensively around the time of the Cretaceous–Paleogene extinction event that killed off the non-avian dinosaurs. Birds in South America survived this event and then migrated to other parts of the world via multiple land bridges while diversifying during periods of global cooling. Primitive bird-like "stem-birds" that lie outside class Aves proper, in the group Avialae, have been found dating back to the mid-Jurassic period. Many of these early stem-birds, such as Archaeopteryx, were not yet capable of fully powered flight, and many retained primitive characteristics like toothy jaws in place of beaks and long bony tails.

Sherlock Holmes (/ˈʃɜːrlɒk ˈhoʊmz/) is a fictional character created by British author and physician Sir Arthur Conan Doyle. A London-based "consulting detective" whose abilities border on the fantastic, Holmes is known for his astute logical reasoning, his ability to adopt almost any disguise, and his use of forensic science to solve difficult cases. The character first appeared in print in 1887, and was featured in four novels and 56 short stories by Conan Doyle, as well as later works by other authors. The first novel, A Study in Scarlet, appeared in Beeton's Christmas Annual in 1887 and the second, The Sign of the Four, in Lippincott's Monthly Magazine in 1890. The character's popularity grew with the first series of short stories in The Strand Magazine, beginning with "A Scandal in Bohemia" in 1891; additional short-story series and two novels (published in serial form) appeared from then to 1927. The events in the stories take place from about 1880 to 1914.
All but four stories are narrated by Holmes's friend and biographer, Dr. John H. Watson. Two are narrated by Holmes himself ("The Adventure of the Blanched Soldier" and "The Adventure of the Lion's Mane"), and two others are written in the third person ("The Adventure of the Mazarin Stone" and "His Last Bow"). In two stories ("The Adventure of the Musgrave Ritual" and "The Adventure of the Gloria Scott"), Holmes tells Watson the story from memory, with Watson narrating the frame story. The first and fourth novels, A Study in Scarlet and The Valley of Fear, include long passages of omniscient narrative of events unknown to either Holmes or Watson.

William WIlliams (? - 1701) was an English composer whose life is not known and his fame rests on his Opus 1 Trio Sonatas, 3 of them written for 2 violins and Basso Continuo, and 3 written for 2 recorders and Basso Continuo. Although influenced by Italian forms, they are still deep-rooted in the English tradition. Williams was an obscure figure, who flourished in Britain around the end of the seventeenth century. His name, plus the fact that he dedicated his opus 1 to James, Earl of Anglesey, suggests inescapably that he was of Welsh origin, despite spending his working life in London. His Sonata In Imitation Of Birds" (Opus 1 No. 6) is from Six Sonata's in Three Parts and was written by Williams in the time of Queen Anne. It is an early eighteenth-century English recorder music piece w...

The program's heyday was in the early 1950s, when radio actor, producer and director Elliott Lewis took over (still during the Wilcox/Autolite run). Here the material reached new levels of sophistication. The writing was taut, and the casting, which had always been a strong point of the series (featuring such film stars as Orson Welles, Joseph Cotten, Henry Fonda, Humphrey Bogart, Judy Garland, Ronald Colman, Marlene Dietrich, Eve McVeagh, Lena Horne, and Cary Grant), took an unexpected turn when Lewis expanded the repertory to include many of radio's famous drama and comedy stars — often playing against type — such as Jack Benny. Jim and Marian Jordan of Fibber McGee and Molly were heard in the episode, "Backseat Driver," which originally aired February 3, 1949. The highest production va...
Banquo is a character in William Shakespeare's 1606 play Macbeth. In the play, he is at first an ally to Macbeth (both are generals in the King's army) and they are together when they meet the Three Witches. After prophesying that Macbeth will become king, the witches tell Banquo that he will not be king himself, but that his descendants will be. Later, Macbeth in his lust for power sees Banquo as a threat and has him murdered; Banquo's son, Fleance, escapes. Banquo's ghost returns in a later scene, causing Macbeth to react with alarm during a public feast. Shakespeare borrowed the character of Banquo from Holinshed's Chronicles, a history of Britain published by Raphael Holinshed in 1587. In Chronicles Banquo is an accomplice to Macbeth in the murder of the king, rather than a loyal subje...
