Safeguards against Boiler Explosions.--In the Congress of Civil Engineers, at the Paris Exposition, Testud de Beauregard suggested the use of suitable thermometers or galvanometers to give tilnely warning of any dangerous disturbance of thermal equilibrium, whether between the boiler and the water or between the water and the steam. Even if the warning should not be given in time to prevent an explosion, it might be the means of saving the lives of engineers, operatives, bystanders or neighbors.--La G~aeeta Indus-~rial.
