PLATE 9 
EXPLANATION OF FIGURES 
33 to 37 Representing the lengths of the chromosomes in the cells indicated 
in the table below at a magnification of 1316. The differences in the lengths of 
the lines and also the spaces between the lines represent relative differences in 
chromosome lengths. For convenience the width of the spaces between the 
lines are made eight times the differences in lengths. The lengths of the chromo¬ 
somes and their percentage of the average length in the cell is sh.own in the 
table below. The amount of foreshortening in any chromosome is indicated in 
plate 8.
