(ii) A second group of papers consists of official and unofficial documents—many of them acquired or copied at some expense—brought together deliberately in order to serve as material for the projected 'History of the Navy.' These include (1) a copy of Sir William Monson's _Naval Discourses_; (2) copious extracts from naval authorities and historians carefully indexed; (3) Penn's _Naval Collections_, being 'a collection of several manuscripts, taken out of Sir William Penn's closet, relating to the affairs of the Navy'; (4) various volumes relating to shipbuilding and navigation, including the curious and valuable work entitled _Fragments of Ancient Shipwrightry_ and Sir Anthony Deane's _Doctrine of Naval Architecture_. This last contains delicate and elaborate drawings of a ship of each rate, and Evelyn records in his _Diary_ under date 28 January, 1682, the remarkable impression which a sight of it made upon him: 'Mr Pepys, late Secretary to the Admiralty, showed me a large folio containing the whole mechanic part and art of building royal ships and men-of-war, made by Sir Anthony Deane, being so accurate a piece from the very keel to the lead block, rigging, guns, victualling, manning, and even to every individual pin and nail, in a method so astonishing and curious, with a draught, both geometrical and in perspective, and several sections, that I do not think the world can shew the like. I esteem this book as an extraordinary jewel.' There also falls into this group (5) the large and important collection in eleven volumes entitled by Pepys _A Miscellany of Matters Historical, Political, and Naval_. This contains copies of 1438 documents, transcribed from various sources, and ranging from a complete copy in 114 folio pages of Sir Philip Meadows's work on the Sovereignty of the Seas down to 'A true Copy of the Great Turke his Stile which he most commonly writeth in His great Affaires.' They include documents relating to naval abuses; papers concerning salutes and the history of the flag, shipbuilding, victualling, and finance; a number of patents, commissions, and lists of ships; transcripts from the Black Book of the Admiralty; and collections relating to the Shipwrights' Company and to the Corporation of Trinity House.
