however, where this split was seen by him, he interpreted it as a 
precocious longitudinal split in preparation for the bomotype division. 
Text Fig. A. may be found useful in comparing the conclusions to 
wbich I have been forced by my preparations witb tbose arrived at 
by Miy ake and Strasburger. 
The observations of the short chromosomes is more difficult, but 
they also generally appear to be attached in the middle and to di- 
vide in the same manner as the long chromosomes; (Figs. 53. 54c. 
PI. IX). They separate more quickly than do the larger ones.

IX. Anaphases. As the loop-shaped chromosomes of both 
sizes move away from each other after division, a second split be- 
comes visible along their whole leflgth, Text Fig. IV'; this is in- 
distinctly shown in Figs. 53. 54 b, but is clearly visible as the chro- 
mosomes approach the opposite poles; (Fig. 55. PI. IX.). Here again 
Miyake has interpreted the loop shape as due to the divergence of 
the two halves of a longitudinally split rod, Text Fig. IV, but a 
split all round the loop is, I think, clearly demonstrated in my pre- 
parations. 
It is very natural to be deceived into dooking upon such a stage 
as Fig. 54 a as a transverse fission across a double loop (at a in 
Text Fig. II'), the fission seen in the limbs of the loop being then
