Page 272 - It is hardly necessary to add, that anything which any insulated body, or system of bodies, can continue to furnish without limitation, cannot possibly be a material substance; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capable of being excited and communicated in the manner Heat was excited and communicated in these experiments, except it be MOTION.
Page 368 - It is impossible by means of inanimate material agency to derive mechanical effect from any portion of matter by cooling it below the temperature of the coldest of the surrounding objects.
Page 341 - It is impossible for a selfacting machine, unaided by any external agency to convey heat from one body to another at a higher temperature, or heat cannot of itself pass from a colder to a warmer body.
