"_Black Book of Scone._"--The _Black Book of Scone_, containing the history of Scotland from Fergus I., was in Sir Robert Spottiswood's library, and was given by Lewis Cant (a Covenanting minister) to Major-General Lambert, and by Lambert to Col. Fairfax; which book Charles I. had ransomed from Rome by a considerable sum of money: and it is certain Archbishop Spottiswood had it and the _Black Book of Paisley_, signed by three abbots, when he compiled his _History_, which, with the famous _Red Book of Pluscardine_, Buchanan says he had, and frequently cites.--Sir George Mackenzie's _Defence of the Antiquity of the Royal Line of Scotland_; and also _Lives of Scotch Writers_. The fate of the _Black Book of Scone_ may be a clue to the inquirer after the _Black Book of Paisley_. It is not now in the library at Spottiswood; and most of Sir Robert Spottiswood's property was pillaged and ransacked during his imprisonment. L. M. M. R. _Cracked Glass._--Some years ago, being a schoolboy at the time, I spent my Christmas holidays at my grandfather's house in Somersetshire. The members of the family were assembled for evening prayer, when suddenly music, resembling that of an Æolian harp, was heard, produced apparently by some person upon the lawn immediately beneath the window. As soon as the prayers were concluded I opened the hall door, and was greatly surprised to find the musician had departed. On returning to the drawing-room I was informed that the moment I had left the room the music ceased. Believing that some village friend had come to serenade us, we drew our chairs round the fire in expectation of his return. A few minutes only elapsed when the music was again distinctly heard. A second visit was made to the hall door, but with no better success. It was then resolved to open the shutters, which was no sooner done than the mystery was clearly explained. During the day a pane of glass had been cracked, and the music was produced by the two pieces of glass vibrating against each other. We found, from repeated experiments, that it required the atmosphere of the room to be at rather a high temperature to produce the effect, for the moment the door, or one of the other windows, was opened, the vibration ceased. I have only to add that the music was very pleasing to the ear, and consisted of rapid cadences. I have often mentioned the circumstance, but I never found any one who had met with a similar _musical fracture_. M. A. _Spanish Verses on the Invasion of England._--I carry in my memory the following verses. Are they to be found in any Spanish canzonero? I certainly have not invented them. "Mi hermano Bartolo Va in Inglatierra A mater et Draque Y a tomar la reyna. Y de los Luteranos De la banda-messa Tiene a traer mi A mi de la guerra Un Luteranico Con una cadena Y una Luterana." . . . . Here my memory fails me. L. H. J. T. Queries.
