BUTLER, CHARLES, a native of Wycomb in the county of Bucks, and a master of arts in Magdalen college, Oxford, published a book with this title: "The principles of music in singing and setting; with the twofold use thereof, ecclesiastical and civil." Quarto, London 1636. The author of this book was a person of singular learning and ingenuity, which he manifested in sundry other works enumerated by Wood in the Athen. Oxon. Among the rest is an English Grammar, published in 1633, in which he proposes a scheme of regular orthography, and makes use of characters, some borrowed from the Saxon, and others of his own invention, so singular, that we want types to exhibit them: and of this imagined improvement he appears to have been so fond, that all his tracts are printed in like manner with his grammar; the consequence whereof has been an almost general disgust to all that he has written. His Principles of Music is, however, a very learned, curious, and entertaining book; and, by the help of the advertisement from the printer to the reader, prefixed to it, explaining the powers of the several characters made use of by him, may be read to great advantage, and may be considered a judicious supplement to Morley's introduction.
