Relation to the Constitution of the EartKs Crust. 7 



where 



log/3=3-7159239. 



But 



Latitude of Punnse= 8° 9' 28", 

 and of 



More =33° 15' 39". 



The correction to gravity for difference of latitude then 

 comes out 



=gx 0-0014589. 



Also correction for height 



2h 



= -#x 0-0014726. 



Hence difference of gravity (SGr) between More and Punnae 

 at sea-level ought to have been 



gx 0-0000137. 



Dividing this by g x 0*0000023148, which corresponds to 

 one swing, it appears that there ought to have been 0*59 

 swing less at More, irrespective of local attraction, than at 

 Punnse. 



Now the observed vibration-number at More was . 85984-62 

 And at Punnse, when reduced to sea-level 85982*95 



Actual difference, SN = +1*67 



So that there were in fact 1*67 swings more ; whereas the 

 difference, irrespective of local attraction, ought to have been 

 -0-5. 



The result is that local attraction at More station needs 

 to account for 2*26 swings in twenty-four hours. 



Reducing this to attraction measure, we may accept as a 

 fact that 



Local attraction at More=# x 0-000052386, 



where g is the attraction of the sphere.
