Abstract
We calculate the net change in generalized entropy occurring when one attempts to empty the contents of a thin box into a black hole in the manner proposed recently by Bekenstein. The case of a ''thick'' box also is treated. It is shown that, as in our previous analysis, the effects of acceleration radiation prevent a violation of the generalized second law of thermodynamics. Thus, in this example, the validity of the generalized second law is shown to rest only on the validity of the ordinary second law and the existence of acceleration radiation. No additional assumptions concerning entropy bounds on the contents of the box need to be made.
