 the object remains suspended between the opposing poles, 

 each of which attracts its peculiar subject " elements." As a 

 result of this attraction the condition in b would presumably 

 occur, and ultimately a separation, as in c, with withdrawal 

 in opposite directions. 



owing to the steady attraction along these lines the chromatin 

 would gradually take the form of a convoluted thread. 



The achromatic poles being equal and similar, one half 

 of the chromatin would lie on one side of the equatorial
