The annexed residuals were obtained by comparing these normals 
with an ephemeris computed from elements (C). The computations 
from the differential formulas were now all repeated, since in the 
previous computations the cheeks showed some discrepancy due to 
neglected second differences. This labor, perhaps unnecessary, gives
