The second part of this table suggests that hairy Hes to the left of ma- 
genta, because when these two factors separate, yellow and crossveinless 
generally go with hairy. This is contrary to the conclusion of Metz (1918) ^ 
who provisionally located hairy between magenta and forked on the basis 
of crosses not involving hairy and magenta simultaneously. The follow- 
ing crosses (table 4), in which all three factors were present at the same 
time, show clearly that the actual order is hairy, magenta, forked.
