ABSTRACT
I cannot judge whether ( actually differs from 2/3 but if it does, the difference does not exceed 1%. It is noteworthy that, in 1957, when paper [96] was accomplished, the variation of Ps by the law (7.56) was not yet known. We, therefore, did not raise an alarm immediately (the A-type behavior of specific heat is less crucial in this respect because it may not be associated with variations of \II', whereas the density Ps is proportional to l\11'12).
