526 The Inconstancy of Fasciated Races. 
to more (Geranium and Crcpis with 65% and 85% ; 
Celosia cristata). 
3. The fasciated individuals and the atavists are con- 
nected by transitional forms, which are, however, rare; 
and the statistical curves representing them have there- 
fore two apices. 
4. These proportions are to a large extent dependent 
on external conditions of life, which can transform ata- 
vists into fasciated plants and vice versa. This trans- 
formation obviously takes place during the plastic period 
in youth, before the character in question is actually de- 
veloped. 
5. The atavists, as well as the selected individuals, 
produce fasciated offspring, and often in proportions very 
little lower than those in which the selected individuals 
produce them. They may therefore be used for the per- 
petuation of the race. 
6. Between the broadened specimens and the atavists 
there is no essential or fundamental difference, in spite 
of the great difference in their external forms.
