 In what way such evidence is to be practically employed will be 

 seen m the succeeding table, calculated by Mr. E. Thompson, 

 with a view to explaining what the natural temperature is to 

 which certain plants commonly cultivated are exposed in the 

 climates best adapted to their healthy development.
