In the second generation the same condi- tion prevailed in the population, with the exception that 10 was absent in the males and only present in the females as a small group, while 11 was present in the males and 12 in the females. Otherwise the distribution of the popula- tion was uncommonly well developed. These conditions are shown in figures 109 and 1
