It is not at all improbable, however, that after we pass the polar circle, 

 a new law comes into operation that will greatly change the results above 

 given. In summer, it will be remembered, there are no days followed 



the difference betw'een what is observed when the sun is at S, and what is absorbed when it is at 



any zenith distance from S, as S'. 



The length of the day is also an element in the calculation. This may be represented to the 



eye by the annexed diagram, in which EW is a straight line denoting and varying with the 



length of the day. On the 21st 

 of March or September, the sun 

 on the equator rises at E, and 

 passes in the arc of the circle 

 through M to W at evening; but 

 at some distance from the equa- 

 tor, say latitude 45°, it reaches 

 only about seven-tenths the dis- 

 tance CM, and its path is denoted 

 by the curve line EM'. But on 

 any day and in a high latitude, 

 when the day is more than twelve 



hours, the curve denoting the sun's path should start at some point outside of E, as at E' ; 'and 



on a day when the time between sunrise and sunset is less than twelve hours, the line should 



start at some point inside of E', as E". 



Now it is manifest that the amount of heat in any solar day is equal to the space contained 



between the base line ECW and the curve line above it, whether it be EMW or E'M'W', &c. 



This curve line is very nearly if not quite an ellipse. I am inclined to think that the ordinates
