The representative for the author of the new experiments on fire, has learned with great distress, Monsieur, that you are ill; and he wishes that the gout leave you as soon as possible: he hopes to have the honor to receive you this Saturday, at the rue de Bourgogne, at the M. le Marquis de l'Aubespine's hotel. MM. the commitee members will be there at nine-thirty in the morning, to profit from the sun.
