//addendum. Nearly got the second bit tight. A couple of word substitutions...

Now let us suppose that that, after it has reached equilibrium with B, one of the bodies, say C, is transferred to a cooler evacuated enclosure D. It loses heat and cools to the temperature of D. Therefore it is radiating energy. But if C, is transferred to a warmer enclosure F then C gains heat and warms up to the temperature of F. i.e. it is absorbing energy. It seems unreasonable that to suppose that C stops radiating when transferred to F; it is more reasonable to suppose that it goes on radiating but, while cooler then F it absorbs more then it radiates.
