increased growth and those which arise from diminished 
action. It will be seen, therefore, that in these in- 
stances it is the bulk of the organs that is increased, 
not their number; moreover, their development or 
metamorphosis is not necessarily altered. In connec- 
tion with increased size an alteration of consistence is 
so frequent that the two phenomena are here taken 
together. It will be borne in mind that the changes 
of consistence from membranous to succulent or woody 
are very frequent in the ordinary course of develop- 
ment. They may also occur as accidental phenomena, 
or the normal conditions of any particular flower or 
fruit may be exactly reversed, the usually succulent 
fruit becoming dry and capsular, and so forth.
