of phaenotype I, 36 of II, 9 of III, 36 of IV, 16 of V, 32 of VI, 
16 of VII and 3 of VIII. In these proportions, one must keep in 
view the lack of difference between BB- and Bb-plants in the 
types I, I, III, IV. A comparison of the numbers observed, with 
the proportions in a total of 269, derived from these theoretical 
proportions, shows a rather good agreement between them:

Only type III, the Wagenaar-type has occurred in a number 
somewhat above the expectation, while type I has remained a little 
below; the deviations however are not strong enough to invali- 
date the theoretical suppositions. The more detailed divisions into 
types I a, I b a.s.o. don’t allow till now more detailed suppositions; 
from groups I and IV a polymeric character of the factor for 
violet marbling could perhaps be concluded to, or from types II b 
and III b the break of a linkage that existed before the crossing 
between a factor for violet and a factor for marbling (that. are 
taken together in this paper as one factor K), but without further 
researches of the F3-and following generations these suppositions 
are far from being justified. 
In any case however this cross has shown with sufficient certainty: 
an independent segregation of the four factors B, G, K and D; 
a distinction between BB- and Bb-plants in the individuals that 
are missing other factors; 
a cryptomeric state of G- and K- factors, if the factor D is absent. 
8. Cross oF BRUINE X KIEVITS. 
In treating the previous cross it was already mentioned, that in 
their seedcoats the F;-individuals from the cross Citroen X Kievits 
are phaenotypically identical with those from Bruine X Kievits. 
Therefore the products of spontaneous hybridizations with the 
Kievits-race as mother cannot be determined immediately in so
