94 MR. J. BAXENDELL : INFLUENCE OF THE SEASONS UPON 



stations in the Caucasian provinces, we have the following 

 comparisons : — 



Four highest Stations. 



Mean annual 

 Height. rainfall. 



Aralikh 2600 feet 6*07 inches 



Alexandropol 4800 „ I5'75 >» 



Alagir 2060 „ 37'67 ,, 



Tiflis 1500 ,, 17*27 ,, 



Mean 2740 i9'i9 



Three lowest Stations. 



Koutais 470 feet 57*94 inches 



Bacou —53 ,, 11*38 ,, 



Lenkoran —65 „ 49*4^ „ 



Mean 117 39'6o 



The ratio of the mean quantities — o"48. 



From the results thus given, it will be observed that, at 

 all the stations lying outside the belt, the ratio is greater 

 than unity, the fall of rain on the mountain exceeding 

 that on the plain; while at stations within the belt the 

 ratio is less than unity, the fall on the plain being greater 

 than that on the mountain. We see therefore that, with 

 reference to the rainfall, there is an inversion of phe- 

 nomena in the belt, similar to that which takes place with 

 regard to the changes of the decrement of temperature with 

 increase of altitude, — and also that, on the average of the 

 year, the rain -producing stratum of the air is relatively 

 of less depth at stations within the belt than at other 

 places — or, perhaps to speak more correctly, that moisture 

 in a state fit for the immediate production of rain is re- 

 latively less abundant in the higher strata of the atmo- 

 sphere in the belt than in the corresponding strata on 

 either side. 



If we compare the ratios of the winter half of the year 

 with those for the summer half at the different stations, 

 we find that a similar relation holds good.
