The Regal here drawn is the prototype of the modern harmonium, but with "beating" not "free" reeds. The beating reed is usually employed in the organ, and it derives its appellation from the reeds touching the sides of their frames. The beating reed was introduced in the fifteenth century, but whether in the simple regal first, or as part of an organ, is not known. In England, the word "regal" has been also used to denote a portable organ, as is shown by Sir John Hawkins's suggestion that the stage direction to the players' scene in Hamlet, "Enter a duke and a duchess with regal coronets," should be "with regals and cornets." The oldest German authorities, as Virdung (1511) and Praetorius (1619), separate them and describe the regal as a reed instrument with key-board exactly like this one, a kind of positive and not a portable organ. This Regal, which was in the Tolbecque Collection, is attributed in date to the end of the sixteenth century. It came from the Abbey of Freuenfeld in Switzerland, and now belongs to the Brussels Conservatoire. Mr. Victor Mahillon, the curator of the museum of that institution, records another fine specimen of this very rare instrument in the possession of the Community of Lady Canonesses of the order of St. Augustine, at Brussels, to which body it was presented, by the founder of the Order, in 1625. The regal is said to have been much used in convents to accompany the singing of the nuns. The Belgian Government kindly allowed a selection of the Conservatoire instruments, of which the Regal here drawn was one, to be played in the Historic Concerts given in July 1885, in the Music Room of the Inventions Exhibition. This instrument, when on its stand, measures 2 feet 8 inches in height, the width is the same, and the length is 4 feet 2 inches. The case is of finely-carved walnut. The compass of the key-board is from the second E below, to the second A above, middle C--about the extent of the human voice, and the frequent compass of old organs. The word "regal" has been derived from the inventor having made a present of the first one to a king, or to kings having had in their establishments special regal-makers. Rigabello, a now unknown instrument which is said to have preceded the organ in Venice, is also quoted as the origin of the name. I have elsewhere (_Encyclopædia Britannica_, article Pianoforte) suggested that "regal" may have come from "regula," a rule, the idea of gradation being inherent in a key-board. The wooden harmonicon, when made to play by a key-board, was at one time called regal (régale en bois). [Illustration: XIII] PLATE XIII. PORTABLE ORGAN AND BIBLE REGAL.
