the oil is left standing for some time, the temperature changes, so 

 that this forms a new source of error. 



I have arranged these observations into four tables according 

 to the class of depth to which each well belongs, the drilled wells are 

 shown in a separate table : — 



/. — Wells below i$i feet in depth. 



Serial number 

 of well.
