_Optical Query_ (Vol. vii., p. 430.).--In reply to the optical Query by
H. H., I venture to suggest that a stronger gust of wind than usual might
easily occasion the illusion in question, as I myself have frequently found
in looking at the fans on the tops of chimneys. Or possibly the eyes may
have been confused by gazing on the revolving blades, just as the tongue is
frequently influenced in its accentuation by pronouncing a word of two
syllables in rapid articulations.
