Chauvenet does indeed discuss it:

He uses stars rather than the Sun, but of course the method should be okay for either. With stars there's more choice of declination, and the time interval can be quite a bit shorter.
Sensitivity to meridian error could be assessed by simulation (well, such is the modern viewpoint; Chauvenet would undoubtedly prefer several pages of trig).
Cheers,
