The fruit was measured again on July 20, when it was 
176 mm. in vertical diameter. It measured 113 on July 12. 
Fig. 8 is a good example of true growth (i.e. continuous 
increase without shrinkings), in which the curve of relative 
humidity is obviously of the same general character as the 
growth curve.
