one place of decimals, these would both have been entered as 
7-8. In the following instances I have picked out cases where 
the temperature varied several degrees in a short time.

On the whole it may be taken that the temperature 
correction makes only a small difference in the decimal 
place, and I have never attached importance to the decimal 
place. 
I have expressed the rate of growth of the fruit in o-ooi mm. 
(f) per minute, not from any exaggerated belief in the 
accuracy of my results, but merely because it is the least 
laborious for calculation 1 . 
1 To facilitate calculation final cyphers were added to some of my original 
notes. It thus unfortunately happens that in my published results three places of 
decimals are given where only two should appear.
