Paris, St. Sulpice, 118 stops; London, Albert Hall, 124; Sydney Town Hall, 144; St. Louis Exposition, 167; Hamburg, St. Michael's, 163, and Liverpool Cathedral, 215. [1] This is really only c|3| (see footnote, page 22), but we have decided to adopt the usual nomenclature. James Ingall Wedgwood, in writing his excellent "Dictionary of Organ Stops," felt it incumbent upon him to offer an apology, or rather, justification for introducing the name of Hope-Jones so frequently. The author of this present volume feels the same embarrassment. He, however, does not see how it would be possible for him, or for any future writer, who values truth, to avoid reiteration of this man's name and work when writing about the modern organ. * * * * * * * * The author's thanks are due to the Austin Organ Company, the Bennett Organ Company, Dr. W.
