From the numbers in the last column, we see that the 

 difference was at a maximum in 1853, ^^^ ^^ ^ minimum 

 in i848_, and that, notwithstanding some slight irregu- 

 larities, there was a tolerably regular increase from 1848 

 to 1853, ^^^ afterwards a tolerably regular decrease to 

 1858. As it is generally believed that the temperatures 

 at low stations are more liable to be affected by acci- 

 dental irregularities than those of stations at a greater 

 elevation, I have also compared Milan with the Great St. 

 Bernard, and have obtained the following differences : —

These differences also show a maximum in 1853, ^^* 

 the minimum is in 1858. A slight examination will, how- 

 ever, show that the irregularities in the first series are to 

 some extent compensated by the irregularities in the 

 second ; and combining the two, we have —
