_The Hon. Spencer Perceval._--Being on a tour through the West of England some years ago, I found myself one morning rapidly advancing up the river Tamar, in the gig of "the Captain of the Ordinary" at Plymouth. We were bound for the noble ruins of Trematon Castle, in the area of which a good modern house has been erected, and in one of the towers is arranged a very pleasing collection of antiquities. As we proceeded up the river, the gallant captain related the following anecdote in reference to the then proprietor of Trematon:-- It is well known that in the afternoon of the 12th May, 1812, the Hon. Spencer Perceval, the then prime minister, fell by the hand of Bellingham in the lobby of the House of Commons; the cause assigned by the murderer being the neglect of, or refusal to discharge a supposed claim he had upon the government. On the same night the gentleman above alluded to, and residing at Trematon, had the tragic scene so minutely and painfully depicted in his sleep, that he could not resist the desire of sending the particulars to a friend in town, which he did by the _up mail_, which departed a few hours after he had risen on the following morning. He informed his friend that his topographical knowledge of London was very meagre; and that as to the House of Commons (the old one), he had seen only the exterior: he went on to state, that, dreaming he was in town, he had a desire to hear the debates in Parliament, and for this purpose enquired his way to the lobby of the House, the architectural peculiarities of which he minutely described; he gave an exact description of the few officials and others in the room, and especially of a tall, thin man, who seemed to watch the opening of the door as any one entered with wild and restless gaze: at length Mr. Perceval arrived, whose person (although unknown to him) and dress he described, as also the manner in which the horrid deed was done: he further communicated the words uttered by the victim to the effect "the villain has murdered--;" how the wounded man was treated, and the person of the medical man who was on the instant called in. These, with other particulars, which have escaped my memory, were thus recorded, and the first newspaper he received confirmed the accuracy of this extraordinary dream. M. W. B. _An Adventurer in 1632._--I transcribe from a manuscript letter now before me, dated "Tuesday, Whitsun-week, 1632," the following passage. Can you or any of your correspondents give me (or tell me where I am likely to find) any further information of the adventurer there named?
