"But one of the pleasantest of our personal remembrances, connected with diamonds, is the picking up of a fine, lustrous gem which fell from O. B.'s violin-bow, (the gift of the Duke of Devonshire,) one night, after he had been playing his magic instrument for the special delight of a few friends."
"It is evenly and not too thickly covered with fine sand or lycopodium powder and then caused to vibrate acoustically by the repeated drawing of a violin-bow with some pressure across the edge of the plate until a steady note becomes audible."
"Stepping into the middle of the room, he took the violin-bow out of his sword-belt, and, holding it over his head with both hands, broke it into a thousand pieces."
