The firebox gases have a tempera-ture of over 2,000 degrees Fahr., and yetin an ordinary locomotive the smokeboxtemperature in regular work is seldomover 750 degrees Fahr., and the gases donot occupy more than about a second intheir passage through the tubes, entailinga much greater drop. The flue gases,however, do not condense, while the steamin the cylinder does; so that we do notknow accurately what the temperature isat the end of the stroke, but it is likely tobe lower than that assumed, viz., 230 de-grees Fahr. That this condensation doestake place is certain, and Prof. Him, ofVienna, devised a simple method of ren-dering the changes visible, by inserting adevice consisting of two short glass tubes,one within the other, and set in brass con-nections, so as to screw into the hole inthe cylinder cover used for taking indi-cator diagrams. The outer tube was pro-vided to protect
