In addition to the Tower, there was in Cromwell's time the fortification of Baynard's Castle, near Blackfriars, and the city gates were also fortifications on a small scale; they were rebuilt (St. John's, Clerkenwell, excepted, which was spared) after the Great Fire, and were taken down somewhere about 1760. Can any of your readers tell me whether there is any series of prints extant of the most remarkable buildings which were destroyed by the fire? There are some few maps, and a print or two interspersed here and there, in the British Museum; but is there any regular series of plates? We know that Inigo Jones built a Grecian portico on to the east end of the Gothic cathedral of old St. Paul's, surmounted with statues of Charles I., &c.; that the Puritans destroyed a beautiful conduit at the top of Cheapside; that Sir Thomas Gresham's Exchange was standing. But among the many city halls burnt down, were there any fine specimens of architecture, any churches worthy of note? And as Guildhall was not entirely consumed, what parts of the present edifice belong to the olden time? You are doubtless aware that the fire did not extend to St. Giles's Cripplegate, and that at the back of the church are remains of the old city walls. ARDELIO. * * * * * BATTLE OF OTTERBURN. On what authority does Mr. Tytler (_History of Scotland_, vol. iii. pp. 45--53.), in his otherwise very fair account of this celebrated battle, assert that the Earl of Douglas was a younger man than Hotspur? I have no doubt that he found it so recorded somewhere, and willingly believed that his countrymen had prevailed, not only over superior numbers of the enemy, but also over greater experience on the part of the hostile general; but a little more investigation would have shown him that the difference of age lay the other way. Henry Percy, by his own account (in the Scrope and Grosvenor Controversy), was born in 1366, and was therefore twenty-two when the battle was fought. I do not know that there is any direct evidence to Douglas's age, but the following considerations appear to me decisive as to his being much older than his rival. 1. Froissart's visit to Scotland was undoubtedly prior to 1366 (although the exact date is not given), and during his stay of fifteen days at Dalkeith, he saw much of the youthful heir of that castle, the future hero of Otterburn, and describes him as a "promising youth." 2. Hotspur, in his deposition above mentioned, says that he first bore arms at the siege of Berwick in 1378; but his antagonist must have commenced his military career long before, as Froissart mentions him as knighted on the occasion of the battle fought a few days after the surrender of that place, between Sir Archibald Douglas and Sir Thomas Musgrave; none but kings' sons were knighted in childhood in those days, or without undergoing a long previous probation in the inferior grades of chivalry.
