and formally opened to the public on 14 January 1875. The west wing was completed in 1888, rooms were opened to the public when they were fitted out, until the last one opened on 14 October 1890. Royal Scottish Museum Administration of the museum was transferred in 1901 from the Science and Art Department to the Scottish Education Department, and in 1904 the institution was renamed the Royal Scottish Museum. Electricity was introduced, replacing the original gas lighting, and powering the first interactive displays in the museum: push-button working models, starting with a marine steam engine and a sectioned steam locomotive. During the period 1871 to 1911 much of the day-to-day running of the museum was undertaken not by the director, but by the curator. The Royal Scottish Museum displayed prank exhibits on April Fool's Day on at least one occasion. In 1975, a fictitious bird called the Bare-fronted Hoodwink (known for its innate ability to fly away from observers before they could accurately identify it) was put on display. The exhibit included photos of blurry birds flying away. To make the exhibit more convincing, a mount of the bird was sewn together by a taxidermist from various scraps of real birds, including the head of a carrion crow, the body of a plover, and the feet of an unknown waterfowl. The bare front was composed of wax. Royal Museum of Scotland In 1985 the museum was renamed the Royal Museum of Scotland, and its administration came under the newly formed National Museums Scotland, along with the Museum of Antiquities which in 1998 moved to a new building constructed as an extension to the Royal Museum at the west end of Chambers Street. National Museum of Antiquities of Scotland The Society of Antiquaries of Scotland was founded in 1780. It still continues, but in 1858 its collection of archaeological and other finds was transferred to the government as the National Museum of Antiquities of Scotland, and from 1891 it occupied half of a new building in Queen Street in the New Town, with its entrance hall shared with the Scottish National Portrait Gallery which occupied the other half. Museum of Scotland The organisational merger of the National Museum of Antiquities of Scotland and the Royal Scottish Museum took place in 1985, but the two collections retained separate buildings until 1995 when the Queen Street building closed, to reopen later occupied
