The ecclesiastical history of the Tudor period may best be studied in the works of John Strype, to wit, _Historical Memorials_, 6 vols.; _Annals of the Reformation_, 7 vols.; _Lives of Cranmer, Parker, Whitgift, etc._, Oxford, 1812-28. See also _Burnet's History of the Reformation of the Church of England_, 3 vols., London, 1679-1715; Neal's _History of the Puritans_, London, 1793; Tulloch, _Leaders of the Reformation_, Boston, 1859. A vast mass of interesting information is to be found in _The Zurich Letters, comprising the Correspondence of Several English Bishops, and Others, with some of the Helvetian Reformers_, published by the Parker Society, 4 vols., Cambridge, Eng., 1845-46. Hooker's _Ecclesiastical Polity_ was published in London, 1594; a new edition, containing two additional books, the first complete edition, was published in 1622. For the general history of England in the seventeenth century, there are two modern works which stand far above all others,--Gardiner's _History of England_, 10 vols., London, 1883-84; and Masson's _Life of Milton, narrated in connection with the Political, Ecclesiastical, and Literary History of his Time_, 6 vols., Cambridge, Eng., 1859-80. These are books of truly colossal erudition, and written in a spirit of judicial fairness. Mr. Gardiner's ten volumes cover the forty years from the accession of James I. to the beginning of the Civil War, 1603-1643. Mr. Gardiner has lately published the first two volumes of his history of the Civil War, and it is to be hoped that he will not stop until he reaches the accession of William and Mary. Indeed, such books as his ought never to stop. My friend and colleague, Prof. Hosmer, tells me that Mr. Gardiner is a lineal descendant of Cromwell and Ireton. His little book, _The Puritan Revolution_, in the "Epochs of History" series, is extremely useful, and along with it one should read Airy's _The English Restoration and Louis XIV_., in the same series, New York, 1889. The best biography of Cromwell is by Mr. Allanson Picton, London, 1882; see also Frederic Harrison's _Cromwell_, London, 1888, an excellent little book. Hosmer's _Young Sir Henry Vane_, Boston, 1888, should be read in the same connection; and one should not forget Carlyle's _Cromwell_. See also Tulloch, _English Puritanism and its Leaders_, 1861, and _Rational Theology and Christian Philosophy in England in the Seventeenth Century_, 1872; Skeats, _History of the Free Churches of England_, London, 1868; Mountfield, _The Church and Puritans_, London, 1881. Dexter's _Congregationalism of the Last Three Hundred Years_, New York, 1880, is a work of monumental importance.
