| 
| Hetherington's contention that Adams' 1925 determination of the 
| gravitational redshift of Sirius B is the result of a deliberate effort to 
| reproduce the value predicted earlier on theoretical grounds is examined. 
| It is emphasized that Adams' measurement may instead be the result of 
| spectral contamination by scattered light from Sirius A, and the 
| plausibility of that suggestion is confirmed by numerical simulations. 
| There is thus, at present, no evidence to support the contention that 
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| Adams may not have acted objectively in this particular scientific 
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| endeavor.
