These numbers are arranged in the following Table according to 

 the temperatures, and, with their mean values (given under the 

 heading " H corrected"), made use of for the calculation of the 

 values of <f>. In another column the variation of <j) for each 10° 

 of change of temperature is given in percentages of $ — thus,
