Therefore, of the averages of the twelve months, six give a higher death-rate with 

 a barometric reading above the average of the several years for those months, and 

 on the other hand, six present a higher death-rate with the barometer below the

Here again, then, it is plain that the accumulated mortality of those months 

 in which there is a high death-rate with a low state of the barometer, is greater 

 than the accumulated mortality of those months in which the death-rate and 

 barometric reading are both above the average. It is noticeable that the average 

 death-rate of those months in which there is a direct relationship between the 

 barometer and the mortality, corresponds exactly with the mean death-rate of 

 the whole term of six years, whilst the average death-rate of the months in which 

 the relationship between the barometric reading and the mortality is inverse, is 

 much higher.
