The following table gives the ratios of the excesses of 
rainfall 8ft. from the ground over the amount measured at 
84ft. from the ground. As I have before shown, any single 
year shows no regularity in the succession of these ratios. 
They are as intermixed for the last year as on any other 
single year. But when six, or any higher number of 
years are taken together, and their average ascertained, then 
a definite order is at once visible. The following table pre- 
sents a nine years’ average of these ratios, and they occur 
in precisely the same order as they do in a six, seven, and 
eight years’ average. Thus, these averages show that the 
greatest difference between the amounts of rain which fell 
in the lower and higher gauges occurs in January, decreases 
gradually in difference till May or June, and, with the ex- 
ception of a slight decrease in September, it continues to 
increase till the maximum is again attained in January. I 
cannot see that this rule demonstrates anything but what
