AT KEW OBSERVATORY AND THEIR DISCUSSION.

Here x, it will be remembered, represents the fraction of the range measured from 

 the lowest point. To test the accuracy of this result, I have calculated the position 

 of the maxima for the several ranges from Table I., which contains, it should be 

 noted, the direct results of observation. The results are as follows : 



Relations between Phenomena for different Ranges. 



11. Our previous work may be regarded as determining the differences between 

 the descending and ascending readings at every point of any range in terms of the 

 mean difference for that range. The next step is to express the mean difference for 

 a range of n inches as a product of / (n) a function whose sole variable is n and a 

 factor which is constant for a given aneroid. 



The mean differences between the descending and ascending readings (defined as 

 in 5) given by the first 24 experiments with the 4 aneroids are recorded in 

 Table VI. 



TABLE VI. Mean Differences (in inches) from the first 24 Special Experiments. 



The most convenient way of dealing with these results is to find the ratios borne 

 by the several mean differences to one of their number for each aneroid separately. 

 For this purpose, I have taken the differences in the range 30-21 inches as standards. 

 The results are given in Table VII.
