only in order to learn whether they constitute a series which 
would indicate that they belong to one cell. Only one set of 
measurements was made. Consequently, the figures are not so 
accurate as those of the other cells. Pairs 1 and 2 are readily 
recognized because they are well separated from each other and 
adjacent pairs. Pair 8 which stood out clearly in figures 33, 34, 
and 36, occupies a similar position here, but its homologues 
according to these less correct measurements differ about 4 mm. 
in length. The relative positions of the pairs practically dupli¬ 
cate those of the other cells. I have not attempted to make 
corrections for foreshortenings, but as nearly as I can judge, the 
chromosomes of pair 1, if corrected for foreshortening, would 
differ in length a little more, homologues of pair 2 would differ 
less in length, and the homologues of pair 8 are foreshortened 
about equally. Approximately the same condition exists in the 
other pairs, so that the matching as indicated would not be 
disturbed sufficiently to alter the grouping of the pairs. In 
this cell chromosomes of pair 12 differ by approximately 10 mm., 
which recalls a second time the condition in pair 9 of figure 33. 
Further consideration of the form of the chromosomes in all 
these figures furnishes additional strong evidence that the chro¬ 
matin is definitely organized. As indicated in anaphases, the 
general form of the chromosomes in the metaphase of these 
somatic mitoses is determined by the point of spindle fiber 
attachment. The complexes represented in figures 27 to 32 are 
early metaphases, and the final form which the chromosomes will 
take is quite apparent, although in some cases (e.g., pair 8, 
fig. 27) it is not entirely clear. 
In all of these figures, as previously mentioned, the form of 
the homologues of each pair is practically the same, even in 
cases where the final form has not been reached. Only three 
pairs (5, fig. 29; 7, fig. 30; 5, fig. 31) are exceptions, and this may 
be expected as indicated by a like condition in the heteromorphic 
pairs of certain Orthoptera (Carothers, T7). A comparison of 
several complexes from the same individual would probably 
show this condition constant for the individual as in the Or¬ 
thoptera. A further comparison of each pair in any figure with
