_Martins, the Louvain Printer_.--Your correspondent "W." (No. 12. p. 185.) is informed, that in Falkenstein's _Geschichte der Buchdrucherkunst_ (Leipzig, 1840, p. 257.), Theoderich Martens, printer in Louvain and Antwerp, is twice mentioned. I have no doubt but this is the correct German form of the name. Mertens, by which he was also known, may very possibly be the Flemish form. His Christian name was also written Dierik, a short form of Dietrich, which, in its turn, is the same as Theodorich. NORTHMAN. _Master of the Revels_.--"DR. RIMBAULT" states (No. 14. p. 219.), that Solomon Dayrolle was appointed Master of the Revels in 1744, but does not know the date of his decease. It may be unknown to Dr. Rimbault, that Solomon Dayrolle_s_ was an intimate friend and correspondent of the great Lord Chesterfield: the correspondence continues from 1748 to 1755 in the selection of Chesterfield's letters to which I am referring. Dayrolles, during all that period, held a diplomatic appointment from this country at the Hague. See Lord Chesterfield's letter to him of the 22d Feb. 1748, where Lord C. suggests that by being cautious he (Dayrolles) may be put _en train d'etre Monsieur l'Envoye_. In several of the letters Chesterfield warmly and familiarly commends his hopeful son, Mr. Stanhope, to the care and attention of Dayrolles. I have not been able to ascertain when Dayrolles died, but the above may lead to the discovery. W.H. LAMMIN. _French Maxim_.--The French saying quoted by "R.V." is the 223rd of _Les Reflexions morales du Duc de la Rochefoucauld_ (Pougin, Paris, 1839). I feel great pleasure in being able to answer your correspondent's query, as I hope that my reply may be the means of introducing to his notice one of the most delightful authors that has ever yet written: one who deserves far more attention than he appears to receive from general readers in this degenerate age, and from whom many of his literary successors have borrowed some of their brightest thoughts. I need not go far for an illustration: "Praise undeserved, is scandal in disguise," is merely a condensation of, "Louer les princes des vertus qu'ils n'ont pas, c'est leur dire impunement des injures."--La Rochefoucauld, Max. 327. I believe that Pope marks it as a _translation--a borrowed thought--not as a quotation_. He has just before used the words "your Majesty;" and I think the word "_scandal_" is employed "_consulto_," and alludes to the offence known in English law as "scandalum magnatum." Your correspondent will, of course, read the work in the original; in fact, he _must_ do so _per force_. A good translation of _Les Maximes_ is still a desideratum in English literature. I have not yet seen one that could lay claim even to the meagre title of mediocrity; although I have spared neither time nor pains in the search. Should any of your readers have been more fortunate, I shall feel obliged by their referring me to it. MELANION.
