tlie chromatin is still able to form the normal clu-omatic 
vesicles in the telophase — in other words, such a stage as 
fig. 21 or fig. 23 is followed by that shown in fig. 25. 
Text-fig. 1 shows two chromosome groups of the same 
spindle in which the chromosomes are apparently all normal 
with the exception of one which lies outside the main group 
and which is somewhat vesicular. It will be noticed that in 
one group there are 30 chromosomes and one vesicle (?) while 
in the other there are only 34 chromosomes. Xow it has been 
shown (Doncaster and Gray) that the normal number of 
clu’omosomes is 38 for each group — a total of 76 for the whole ; 
Text-fig. 1. 
Two chromosome groups of the same spindle of an egg of E. 
escnlentus. series C. In the left-hand group are thirty-four 
chromosomes, and in the right thirty-nine plus a dot. 
this spindle only shows 73 to 75; the latter number if the 
chromatin body lying outside the two main groups represents 
a swollen chromosome which has failed to divide and has not 
been attracted to either pole. This shows that, owing to 
irregularity in the earlier stages of the division, both halves 
of a certain number of chromosomes must have passed to 
one and the same pole. This may be due to the fact that 
when division took place the mother chromosomes were lyfing 
abnormally nearer to one pole than to the other, so that both 
halves went to the same pole. 
That irregular distribution of chromatin between the two 
poles does take place is seen in many of the more irregular
