distributed as shown in figures 11 and 12. Sharp (’13) points 
out that in certain resting nuclei of Vicia heavier bands repre¬ 
sent the reticulate chromosomes of the telophase joined together 
by fine anastomoses as a continuous net. My results in general 
agree with those of Sharp, but I am of the opinion that, even 
when the chromosomes become indistinguishable as such in the 
resting reticulum, they again condense during the prophases. 
Sharp does not represent the stages shown in my figures 11 and 
12, which I regard as very early prophase stages that should come 
before the prophase stage in Sharp’s figures 1 and 2, which latter 
figures I regard as representing a rather advanced prophase 
stage, and not a true resting condition. 
These bands formed from the resting reticulum are at first 
broad and very reticulate. In figure 13 two such bands may be 
seen on the right of the nucleus. This represents about the same 
stage as Gregoire (’06) figures for Allium, and I have often seen 
similar figures in that plant. This author holds that the reti¬ 
culum is transformed into a series of alveolar-reticulate or spongy 
bands, united by lateral anastomoses. I can agree with this in¬ 
terpretation, except that I do not find the lateral anastomoses 
abundant in normally fixed preparations. As the chromosomes 
do not anastomose during the reconstruction stages of the nuclei, 
no laterial anastomoses appear, except in material improperly 
fixed. In figures 24 and 25, which are drawn from preparations 
fixed in Flemming’s fluid, such anastomoses are present, but I 
do not regard this as a normal appearance. As Gregoire says, 
the reticulum is thus resolved into a series of bands more or less 
parallel, each of which possesses the same structure as the nuclear 
reticulum. 
“C’est comme si, dans ce reseau, on avait fait passer au rateau. Image 
seulement, car se qui s’est reellement produit, c’est une. concentration.” 
Sharp (’13, ’206) also represents the chromosome bands as 
connected by lateral anastomoses, and points out that the inter¬ 
pretation placed upon the resting nucleus does not correspond 
with that of Fraser and Snell (’ll) and of Lundegard (’09, 
’10 a, ’12c). It may also be added that Digby (’19) agrees with 
the opinion of Fraser and Snell that the resting reticulum con¬ 
sists of faint granules in which the individual chromosomes are 
indistinguishable. Such preparations as that shown in figure 13 
are the only evidence that I can find that the chromosomes, which
