for the point r :> a. 



In the next diagram, the general march of the function 



assin"^ — — \— is exhibited, where x is the ratio of the distance 



of the point under consideration from the centre of the loaded 

 circle to its radius. The course of the curve is very similar to that 

 of Fig. 6, except at the point very near to the edge of the loaded 

 area, where, in this case, it remains finite. 



For example, with the same assumption regarding the 

 material constants of the earth as in the former example, and 

 supposing that the total amount of the load is the same as before, 

 i.e. the mean lieight of the tide is one metre, anda=2xl0^, >•= 

 X 10^ cm, we have
