He is concerned about the reading from the thermocouple inside the cell, since it is the one exposed to either hydrogen or deteurium. He is suggesting the D2 and H2 *might* breakdown into D and H at slightly different rates and this explains the different temperature readings. I don't know if a) they do breakdown at different rates and b) if this breakdown can account for all the heat generated over the course of the experiment. Harry
