The variation of the seeds in Kojitnikan shows a monomodal 

 curve, as well as in that of Kishumikan, where a little irregu- 

 larity- is caused by scanty material. The correlations in both 

 mandarins, as the tables show, are remarkable, especially in 

 Kojimikan. These two facts point to their strong fertility, be- 

 cause many vesicled fruits in poorly fertilized mandarins have 

 not necessarily many seeds.
