DETERMINATION OF DEFLP:CTION OF LIGHT BY THE SUN’S GRAVITATIONAL FIELD. 323 
are found to be 
58/+ 2-838k = — 1 
2'83^ “b 4'838 /c = -f-64 
whence 
3*23S/c = +64, 
S/c = +20. 
An increase of 20 on 184 corresponds to an increase of 0"-19 on l"-75. Hence the 
resulting deflection at the limb is l"-9'4. 
Since the full deflection is indicated we complete the results for x by taking out the 
remaining |E^, obtaining A^x, and then tabulate the residuals from the mean values 
—5942.
