I have taken first for each station separately the temperature differences of 

 each pair of homonymous months in consecutive j^ears, rejecting as before 

 all those in which the instrument has been changed in the interval ; and 

 next the mean of all the differences thus obtained for the same pair of 

 months. A rise of temperature is indicated by -f , a fall by — .
