 polar circle, a new law comes into operation that will gi^eatly 

 chano'e the results above o^iven. 



In summer, it will be reroiem- 



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 



M 



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 equator, say latitude 45 deg., it reaches only about seven-tenths
