THE RATE OF DECREASE OF TEMPERATURE^ ETC. 89 



of 9809 feet above the sea, but does not state the number 

 of years from wbich bis results are derived. His results, 

 however, compared with those given above for Messina 

 and Catania, agree in showing a greater difference of tem- 

 perature between the high and the low stations in winter 

 than in the summer months. 



Proceeding again in an easterly direction, we arrive next 

 at the mountainous region lying between the Black Sea 

 and the Caspian, where we find several important stations 

 well suited for our pupose, at which for some years me- 

 teorological observations have been made by direction of 

 the Russian Government. These stations are —
