In this paper, the following points are dealt with:– (1) In Part II of this series, the effect of a variation in the evacuation temperature on the nature of the subsequently determined isothermal was investigated in the cases of charcoal C and D. The results indicated that, if displacement of oxygen from the surface of the charcoal were complete, the evacuation temperature (up to 800°C.) was unlikely to have much effect on the isothermal. In Part III it was suggested that the isothermals might perhaps prove to be identical, allowance being made for any minor differences in surface structure brought about during the elimination of the oxygen. Further experiments have been done which, whilst indicating that the effect of high temperature degassing can be much greater than was found in Part II, support the views already put forward on the part played by adsorbed oxygen (experiments 1 to 5).
