"Konig, all filial gladness, is received gladly;--though, by degrees, with some surprise, on the paternal part, to find Konig ripened out of son, client and pupil, into independent posture of a grown man. Frankly certain enough about himself, and about the axioms of mathematics. Standing, evidently, on his own legs; kindly as ever, but on these new terms,--in fact rather an outspoken free-and-easy fellow (I should guess), not thinking that offence can be taken among friends. Formey confesses, this was uncomfortable to Maupertuis; in fact, a shock which he could not recover from. They had various meetings, over dinner aud otherwise, at the Perpetual President's, for perhaps two weeks at this time (dates all to be had in Formey's Note-book, if anybody would consult); in the whole course of which the shock to the Perpetual President increased, instead of diminishing. Republican freedom and equality is evidently Konig's method; Konig heeds not a whit the oracular talent or majestic position of Maupertuis; argues with the frankest logic, when he feels dissent;--drives a majestic Perpetual President, especially in the presence of third parties, much out of patience. Thus, one evening, replying to some argument of the Perpetual President's, he begins: 'My poor friend, MON PAUVRE AMI, don't you perceive, then'--Upon which Maupertuis sprang from his chair, violently stamping, and pirouetted round the room, 'Poor friend, poor friend? are you so rich: then!' frank Konig merely grinning till the paroxysm passed. [Formey, i. 177.] Konig went home again, RE INFECTA about the end of the month." Such a Konig--had better not have come! As to his strictures on the LAW OF THRIFT, the arguings on them, alone together, or with friends by, merely set Maupertuis pirouetting: and as to the Konig Manuscripts on them "to be published in the Leipzig ACTA, after your remarks and permission," Maupertuis absolutely refused to look at said Manuscripts: "Publish them there, here, everywhere, in the Devil and his Grandmother's name; and then there is an end, Monsieur!" Konig went his ways therefore, finding nothing else for it; published his strictures, in the Leipzig ACTA in March next,--and never saw Maupertuis again, for one result, out of several that followed! I have no doubt he was out to Voltaire, more than once, in this fortnight; and eat "the King's roast" pleasantly with that eminent old friend. Voltaire always thought him a BON GARCON (justly, by all the evidence I have); and finds his talk agreeable, and his Berlin news--especially that of Maupertuis and his explosive pirouettings. Adieu, Herr Professor; you know not, with your Leipzig ACTA and Fragment of Leibnitz, what an explosion you are preparing! Chapter VII.--M. DE VOLTAIRE HAS A PAINFUL JEW-LAWSUIT.
