Jean-Baptiste-Claude Delisle de Sales (1741 - 1816) published what seemed to be an interminable series of volumes bearing the title De la Philosophie de la Nature, with the first volume appearing in 1770. Few of his contemporaries seemed to feel that the number of volumes and the overall length of the project produced insights or innovations.
