 subject; and breaking strength of straw, in grams, relative 



r= .863 ± .010 



which is also significant. In this Hne the greatest correlation is found 

 with the greatest crowding. It appears, then, that there is an increase 

 in correlation with increase in crowding, but that the lunit is reached
