1822. Excerpt: ... APPENDIX (B). Abstract of Evidence and Reports
made by a Select Com? mittee of the House of Commons, on Steam

after it had arisen from the fire, to return into the heat of the
fire before it entered into the flue or chimney, and so was
consumed; 2dly, By putting on no more fuel at any one time than the
smoke of which can be so consumed, and that without opening the
