rings (here reproduced as Figs. 2 A-E) and of the double 

 crosses (here Figs. 6 H C). On the other hand a study 

 of my Fig. 4 will show that the results of the division, as 

 stated by Janssens himself (my Fig. 4 C 1 ) can only be 

 brought about by a split which passes straight through 

 the equational cleft of the horizontal rings and leaves the 

 chiasma untouched. I infer, therefore, that Janssens 

 does in fact consider the chiasmatypy to have taken place
