Lupinus albus. —In considering the intervals here we 
have obviously the same difficulties encountered in dealing 
with the positions. Here also the average of all the operated 
cases will be dealt with first and this will be followed by a 
treatment of the special cases. From the general averages 
of Tables V and VI we get the intervals shown in Table XIII. 
Taking into consideration in the operated series only the 33

The changes in the intervals : as A eeere out by the differ- 
ences between the averages in the cases of minor rotation and 
the normal cases (Table XIV and / g) show a very close 
approximation to a condition in which nearly all the rotation 
has been confined to B and C and in which C has moved 
twice as far as @. Such a rotation would, as stated on page 
157, give us an equal increase in intervals AB and BC and 
no change in interval HA. Here we get an increase of 10.2° 
in AB, of 11.3° in BC, and of .8° in A, a very close agree- 
ment indeed. In Parthenocissus a similar result is not ob-
