42 ANIMAL INDIVIDUALITY [CH. 



becomes as perfect an individual as its parent. It is, 

 however, in this relation of parent to offspring that 

 division is at variance with budding. Instead of one 

 individual producing another, here the founder of the 

 race ceases to exist, losing his own individuality in 

 the production of two fresh ones. A glance at 

 Fig. 4 will show that the whole substance and the 

 whole organization of the first individual is separated 

 in division into two discrete masses, each of which is 

 incomplete in possessing only half the normal structure. 

 These incomplete individuals, in the examples we have 

 chosen, and in many other animals as well, do not as 

 one might expect complete themselves by keeping the 

 old half-organization intact and budding out what is 

 missing, but, by a method involving a more radical 

 destruction of the parent's individuality, they remodel 

 their structure by a strange internal mason's-work, 

 turning the materials that but now constituted a half- 

 individual into a whole. From their parent they 

 receive the half of its substance and the half of its 

 organization ; they make a new organization without 

 adding to the substance 1 . Growth subsequently 

 increases their size without altering their individuality 

 or organization, until, on attaining to the prescribed 



1 Or at least without adding more than a very small amount. 

 Normal growth may go on, but the re-modelling goes on still faster. 

 That growth and reorganization are not necessarily connected is 

 shown by the strange facts narrated on p. 145.
