In our latitude?, the j'ltitiide of the point of nmgel.it ion may be found 

 with sufficient prrri-ioii I>\ multiplying the mean temperature 3~2 by 

 300, and correcting as in Art. Jl'. 



"We will conclude this Article \\itli the following short Tables and ob- 

 servations :

The difference of mean temperature between summer and winter 

 (reckoning each to consist of three months), is nothing- at the equator, 

 and constantly increases as we approach the pole, ;;,> bhown in the fol-

The following Table of mean annual temperature, drawn up princi- 

 pally by M. de. Humboldt, is worth the attention of meteorologists. 

 Those cities, to which an asterisk is attached, are, singularly situalrd 

 with respect to climate, either by their elevation above the level of the 

 ocean, or l>y circumstances independent of the latitude :
