Fig. 10. 



Curves plotted for olive oil at different temperatures from Tables XXIII and XXV. 

 The dotted curve is got by a process of interpolation roughly from Table XXIV. 



Afc the higher temperatures the rate of leak was so great that 

 there is some doubt as to the first reading of the deflection : hence 

 the discrepancies in the values of the ratios. 



Tables XXIV and XXVII are abridged from fuller tables which 

 give readings taken at 15 seconds intervals. These are given below.
