found. This condition of polyploidy arises by double chromosome reproduc- 

 tion during the resting stage. In the prophase and metaphase of certain of 

 these polysomatic cells the chromosomes are in closely associated pairs. 



In Spinacia oleracea, therefore, more than two chomonemata may be 

 present in closely paired association. In such multiple associations there is 

 no evidence of any repulsion between pairs. Paired associations are main- 

 tained from earliest prophase to metaphase without being held together by 

 chiasmata. 



After the discussion of these talks, Dr. Gager expressed the 

 thanks of the Torrey Botanical Club to Father Berger and his staff 

 for their kind hospitality. The meeting was adjourned at 5 :45 p.m.
