The following section deals with i tction

niceus, and //. konig albert, shown quantitative 



cl ii'. ■ . - in the behavior toward differenl n a 

 at definite time intervals. (Charts D LOG to D 126.) 



The i! ispicui us features of these charts are : 



( i ) The marked tendency for the curves of //. kath- 

 I the hybrid to run togi ther, usually verj 

 closely, and well separated from the curve of H. punt 

 Both i latures are well i I in all i re: ctions, 



with the exception of those with chloral hydrate, pyro- 

 gallic acid, sodium salicylate, and barium chloride. 

 Even in these instances th itionship of //. 



kailn rina and the hybrid is evident.

curve of thi hybi id is cui tlj lowi i

 in number, the starches of both II. katherina and the 

 hybrid are so resistant thai such di ' as are re-
