Abstract
PROF. AMBARZUMIAN seems to have misunderstood my main point. I did not intend to claim that equipartition actually exists—Prof. Ambarzumian's arguments (2) and (3) are sufficient to disprove this—but that in certain respects there is a tolerably good approximation to equipartition. To obtain perfect equipartition would, of course, require an infinity of time ; to obtain the observed approximation requires time of the order of 1013 years. I cannot see that Prof. Ambarzumian's remarks in any way challenge this position, so that it seems to me that the observational data he mentions are not opposed to the long time-scale of 1013 years, but only to an infinitely long time-scale.
