Some of the games in the Traité Théorique et Pratique du jeu des Echecs, par une Société des Amateurs." Paris; Stoupe, 1775

"The 'Traité des Amateurs' was composed, as its title imports, by a Society of Amateurs, the contemporaries of Philidor; who all frequented the Café de la Régence, in Paris. Of these, the chief in skill were Bernard, Carlier, Leger, and Verdoni; which last celebrated Chessprofessor died in England, and was, says Sarratt, " incontestably a player of the first order." Philidor, constantly resident in London, naturally took no part in writing the "Traité des Amateurs;" which in fact embodies many criticisms and comments upon his earlier printed book. In making up the work before us, it is understood that the great masters above named produced most of their games and examples, by playing them over, experimentally and repeatedly, with each other; consulting upon the moves in committee, and noting down the details and variations contingent upon each result. The natural consequence of this develops itself in the practical character of the Treatise; presenting, indeed, fully as much the complexion of a vast collection of first-rate games, played out, mostly even to the closing Checkmate, as that of a general work on the subject of Chess..."
