“…Comparison of calculated and measured densities at 25°C.Kuschmann, 8 who have shown the effects of chemical treatment and of annealing under various conditions upon the densities, and ofMaier,9 who investigated the effects of various mechanical and heat treatments on the densities. The remarkably high value for a large single crystal of copper (cf.Table V)is entirely beyond the range of any normal errors and has not been explained.It is interesting to calculate K from Eq.…”
