Side 64 - The tendency of the results of these experiments shows that low gradients on railways are not attended with the advantageous effects which have been hitherto ascribed to them; that, on the contrary, the resistance produced by steeper gradients can be compensated by slackening the speed, so that the power shall be relieved from as much atmospheric resistance by the diminution of velocity, as is equal to the increased resistance produced by the gravity of the plane which is ascended.

Side 73 - ... variable quantity of oxygen : it was, in fact, atmospheric air deprived, by the heated metal, of more or less of its oxygen. 2. That this air was derived, principally, from the current into the boiler when surcharged steam had ceased to be formed, and the boiler was left dry ; there will, therefore, be no such quantity in a working boiler, where the air must be supplied from the cold water thrown in. 3. That water in contact...
Side 66 - To find the volume or space the steam of a cubic foot of water occupies when the steam is of a given elastic force and temperature, and separated from the liquid from which it was generated, — RULE.
Side 65 - The theorem, however, is valuable to practical men, not only as being applicable to numerous other branches of mechanical inquiry, but as leading directly to the methods by which some of the best rules have been obtained for calculating the elasticity of steam, when in contact with the liquid from which it is generated. We now proceed to apply our formula to the determination of a general law, or such as will nearly represent the class of experiments on which it rests ; and for this purpose we must...
