 than a man of sixty. If the activities of cicatrization are 

 referred to that of the age of twenty taken as the unit (lOo) the 

 curve shown in Fig. 28 is obtained. This, hke the preceding 

 one, clearly shows the very rapid decrease of this activity in 

 the first years of life and the tendency to reach a low and
