Other observa

ables for their verification. 



Among t 



lese I may 



specify the fol- 



lowing : " The increase of vernal temperature is great (from 14*^4 

 or 16^ in the space of a month,) and equally prolonged, wher- 



unequal, as in the north of Europe and in the temperature of the 

 United States." And again, " In all places, whose mean temper- 

 ature is below 62°6, the revival of nature takes place in spring in 

 that month whose mean temperature reaches 42°8 or 46°4. 

 When a month rises to 41^9 the peach flowers.

51 8 the birch tree (Betula Alba) pushes 



On one point I have found a difference. Baron Humboldt, in 

 opposition to Kirwan, and from observations deduced from numer- 

 ous European tables, asserts that the mean temperature of Octo-
