"[T]here is one writer, whose inventions have especially served as the type of many a modern fire-place, and at the time of their introduction in 1713, showed a great and sudden advance in the art of warming apartments. It has been said... that the author... was no less a man than the Cardinal Polignac, who, under the assumed name of Gauger, published a treatise, entitled "La Mechanique du Feu, ou l'Art d'en augmenter les effets et d'en diminuer la dépense, contenant le Traité de Nouvelles Cheminées qui echauffent plus que les Cheminées ordinaires, et qui ne sont point sujettes à fumer" [The Mechanics of Fire, or the Art of increasing its effects and reducing its expenditure, containing the Treatise on New Chimneys which heat much more than ordinary Chimneys, and which are not subject to smoking] This treatise was reprinted at Amsterdam in 1714, and a translation of it, by Dr. Desaguliers... was published in London in 1716."
