'The work contains the words of 393 anthems, besides tunes of chants, &c., 'Brief Directions for the understanding of that part of the Divine Service performed by the Organ in St. Paul's Cathedral on Sundayes;' a 'Scale or Basis of Musick,' by Dr. Ralph Winterton, regius professor of medicine at Cambridge, and a 'Psalm of Thanksgiving,' sung by the children of Christ's Hospital, set to music by Thomas Brewer.The book is valuable from a liturgical point of view, besides which it has preserved a record of many anthems by English church composers which are now lost.
