  Rotation curves for four spiral galaxies with recently determined
Cepheid-based distances are reconsidered in terms of modified Newtonian
dynamics (MOND). For two of the objects, NGC 2403 and NGC 7331, the rotation
curves predicted by MOND are compatible with the observed curves when these
galaxies are taken to be at the Cepheid distance. For NGC 3198, the largest
distance for which reasonable agreement is obtained is 10% smaller than the
Cepheid-based distance; i.e., MOND clearly prefers a smaller distance. This
conclusion is unaltered when new near-infrared photometry of NGC 3198 is taken
as the tracer of the stellar mass distribution. For the large Sc spiral, NGC
2841, MOND requires a distance which is at least 20% larger than the
Cepheid-based distance. However, the discrepancy of the Tully-Fisher and SNIa
distances with the Cepheid determination casts some doubt upon the Cepheid
method in this case.
