'Modus tenendi Parliamentum apud Anglos. In twoe bookes. Composed by Henry Ellsing, Clerk of the Parliaments.’ For a notice of Sir Henry Elsynge (c. 1606-1656), see Anthony Wood's Athenæ Oxoniensis, where this work is said to have been mostly taken from one with a similar title by the father of Sir Henry (Henry Elsynge, bap. 1577-1635), who was clerk to the House of Lords, as the son was to that of the Commons. Henry Ellsing, Clerk of the Parliaments, must be the father, as that title belongs to the Clerk of the Upper House: the son, who published the book, was Clerk of the House of Commons.
