§ 5 Accuracy of the adjustments. 



Fiom the results of table III we derive the following data. 

 The deviations from the mean which must be ascribed partly to 

 the regulation of the temperature are small and when reduced to 

 differences of temperature they remain below 0°.005. 



The mean of the results of the large and the small pattern derived 

 separately for each series gives: 



Series I, large pattern p — 806.65 (2 observations)
