By substraction the « of the comparison plates the scale plate is 
eliminated, and we derive from right ascensions «-=-+-0.105" and from 
declinations «=-+0.098". 
Reference to the normal equations shows that the declination re- 
sult is of double the weight of that from the right ascensions. 
Thus 
a= -+0.100"= +.0.625””, 
This is at a distance 50’ from the sun’s center. At the time of the 
eclipse the sun’s radius was 15.8’; thus the deflection at the limb 
as) 1.987": 
The range in the values of @ is attributable to the errors inherent 
to the star images of the different plates, and can not be reduced by
