The following is the axiom ou which Clausius' demonstration is founded : — It is impossible for a self-acting machine, unaided...any external agency, to convey heat from one body to anot/ter at a higher temperature. It is easily shown, that, although this and the axiom I have used...

...Clausius went much further. He claimed that Clausius's 'demonstration' was founded on the axiom that 'It is impossible for a self-acting machine, unaided...from one body to another at a higher temperature'. Not stated anywhere in Clausius's 1850 paper, the axiom had been constructed by Thomson in such a fashion...
