From these numbers it is evident that in unhealthy years 

 the increase of mortality is relatively greater between the 

 ages of 25 and 75 than at any other age, and that very 

 young and very old lives are relatively much less affected 

 than in years when the general rate of mortality is below 

 the average,, thus confirming the view I have taken that 

 the excess of deaths in unfavourable years is principally 

 due to meteorological causes. 



It has long been admitted that the state of the public 

 health is affected by changes in the state of the weather ; 

 and for many years the Registrar General has regularly 

 included in his Reports statements of the weekly, quarterly.
