differences between the two periods occur with east, south- 

 east, and south winds. Comparing the mean temperature 

 under south-west winds with that under south and south- 

 east winds we have following differences : — 



1858 +0-35° 



1859 +0-75 



1860 +2-20 



1861 +0-85 



1862 +0-25 



1863 -0-30 



Here we have again a maximum in 1860 and a minimum 

 in 1867. 



As the temperature diminished under two winds only, 

 the north-east and south-west, we may compare the means 

 of the temperatures under these winds with those of the 

 wind under which the greatest increase of temperature took 

 place, the south-east, thus : — 



Again we have a maximum in 1860 and a minimum in 

 1867, and it is therefore evident that the distribution of 

 temperature under different winds, like that of barometric 

 pressure, is very sensibly influenced by the changes which 

 take place m solar activity.
