OSCILLATIONS AT GENEVA AND GREAT ST. BERNARD. 9 



We now come to the effects of temperature above or 

 below the average, as given in Table VI. 



In January, February, and December, a temperature 

 above the average at Geneva is accompanied by a greater 

 amount of oscillation than when the temperature is below 

 the average : in the months of March, April, May, June, 

 July, August, September, October, and November, the 

 opposite of the above holds good. 



On the mean of the year, a temperature below the 

 average at Geneva gives a larger amount of oscillation 

 than a temperature above the average. 



At the Great St. Bernard, temperatures above the 

 average, in the months of August and September, give a 

 larger amount of oscillation than temperatures below the 

 average : the months of January, February, March, April, 

 May, June, July, October, November, and December give 

 the converse of the above. 



For the year, a temperature below the average at the 

 Great St. Bernard gives a larger amount of oscillation: 

 than a temperature above the average. The months of 

 December, January, and February, at Geneva, appear to 

 correspond, in their relations to the amount of oscillation, 

 with the months of August and September at the Great 

 St. Bernard. 



A number of oscillations above the average at Geneva, 

 in the months of January, March, June, July, August, 

 and November, is accompanied by a larger rain-faU than 

 when the number of oscillations is below the average. In 

 the months of February, April, May, September, October, 

 and December, the opposite of the above takes place. 



Upon the mean of the year, a number of oscillations 

 above the average is accompanied by a larger amount of 

 rain-fall than when the number of oscillations is below the 

 average. 



At the Great St. Bernard, a number of oscillations
