I quote this from an admirable paper in _The Times_ of to-day (April 10.) on the Crystal Palace, and quote the subscribed from an _Essai sur la Marquise de Pompadour_, prefixed to the _Mémoires de Madame du Hausset, Femme de Chambre de Madame Pompadour_, in Barrière's _Bibliothèque des Mémoires_. "Madame de Pompadour, dans l'ivresse de la prospérité, répondit à toutes les menaces de l'avenir par ces trois [_quatre_] mots, "APRÈS NOUS, LE DÉLUGE," qu'elle répétait souvent." In this case, "Pompadour _v._ Metternich," surely a verdict must be returned for the lady, unless Voltaire puts in a future claim. DOUGLAS JERROLD. West Lodge, Putney Common. * * * * * BISHOP THORNBOROUGH'S MONUMENT. [The writer of the following interesting communication does not appear to be aware that he is obliging us and a correspondent D. Y., who had asked (Vol. iii., p. 168.) for an explanation of the phrase _Denarius Philosophorum_, in the Bishop's Monument.] Our local antiquaries have long been puzzled by an inscription in the Lady chapel of our cathedral. It stands on the monument of Bishop Thornborough, and was prepared by himself fourteen years before his decease in 1641, at the age of ninety-four. He was addicted to alchymy, and published a book in 1621, entitled [Greek: Lithotheôrikos], _sive_, _Nihil aliquid_, _omnia_, _&c._ In the course of some recent studies in the Pythagorean philosophy, my attention was accidentally engaged by this {300} inscription; and it at once struck me that it was _thence_ that the explanation was to be derived. The epitaph is as follows: on one side, "Denarius Philosophorum, Dum Spiro, Spero." on the other, "In Uno, 2^o. 3^o. 4^{or} 10. non Spirans Spera_bo_." The latter letters are now effaced. It is well known that the Pythagoreans found all the modes of space in the relations of numbers.
