The loss of weight occurs between 2*i and 2*33. The chief 
increase in rate is from 5.20 to 8, after which a distinct fall in 
rate takes place. This fall is of frequent occurrence, both as 
to changes in weight and changes in size.

Exp. 3 is graphically represented in Fig. 1, Plate XXII : the 
unbroken line represents change in weight, the broken line 
change in temperature It will be seen that at 11 a.m. and 
2 p.m. the temperature rises suddenly and falls again, and at 
both these points the growth curve falls and rises, i.e. varies 
in the opposite direction to the temperature curve. This is a 
very general occurrence, both in regard to the curve of weight 
and of size. It is certain, from later observation with the dry 
and wet-bulb thermometer, that the hygrometric state of the 
air is the chief factor in determining changes in the rate of 
growth. Therefore the contrast between the growth and
