Amongst the treasures relating to Shakespeare are the only known MSS. of his plays written before the close of the seventeenth century. The first of these, which is supposed to have been written about the year 1610, is “The History of King Henry IV.,” the two parts in one, and consists of fifty–six leaves. It is generally believed to be in the handwriting of Sir Edward Dearing, of Surrenden, Kent, and to have been transcribed by him from some other MS. since lost, as no printed copy is extant containing the various corrections and alterations shown in this MS. There is also a volume of MS. poetical pieces, including a copy of “Julius Cæsar,” transcribed in the reign of Charles II. This play, it is clear from the enormous variations from all printed editions, must have been transcribed from some independent version, and it seems more than probable from an ancient playhouse copy. In addition to these notable MSS. there are a fine copy of the folio edition of 1623; a “Hamlet,” 1607, 1637, 1676; the second part of “King Henry VI.,” 1619; “King Lear,” of 1608; “The Merchant of Venice,” of 1600; as well as a “Romeo and Juliet,” 1599; and a very interesting collection of wardrobe and property bills of the Theatre Royal, Drury Lane, dating from 1713 to 1716. Of great interest outside the more domestic portion of the castle is Cæsar’s Tower, in the dungeons of which so many persons during past ages must have been confined, some of them doubtless never to be released save to go to execution. The dungeon—on the walls of which are rudely scratched inscriptions, drawings of bows and arrows, crucifixes, and coats–of–arms—is a strong, stone–vaulted chamber 17 feet by 13 feet and 14 feet 6 inches high. The roof is groined in two bays, and on the south side is a plain semicircular opening, admitting a beam of light from a deeply splayed window about 6 inches wide. On the same side of the dungeon is a passage cut off from the prison by an iron grating, so as to prevent access. From the top of Guy’s Tower, which is reached by a staircase of one hundred and thirty–three steps, there is a fine general view of the castle itself, as well as the wide prospect of the surrounding country A noticeable feature of the tower is the immense strength of the vault beneath it, which would apparently point to the fact that in olden days some heavy engine for the purpose of slinging stones must have been placed upon the roof. In the tower there are five floors, each having a groined roof, and subdivided into one large and two small rooms, the sides of which in most cases are pierced with numerous loopholes for bowmen commanding in all directions the curtains which the tower was built to protect.
