128 A CYTOLOGICAL INVESTIGATION OF SOME SPECIES 
In fig. 17 an anaphase is pictured, viewed from one of the poles. The 
two chromosomeplates were met with in the same section, lying some- 
what obliquely, but both could well be focussed. In each of them 56

chromosomes could with certainty be counted, all had approached the 
poles up to nearly the same level, so that there could be no question 
of chromosomes having lagged behind.

That in this stage 56 chromosomes were found clearly shows that really 
56 gemini are formed in the PMC. If, between the 56 chromosome-ele- 
ments in the nuclear plate, univalent chromosomes had been present, 
these would — as will be presently seen — behave in such a way, that 
one would reach other results in the anaphase.
