different degrees of humidity; and in consequence of the stratification of 
the upper and lower winds, this blending offers a unique opportunity for 
the practical study of the opposite tidal tendencies in deep and shallow 
fluid seas or envelopes. If the lunar are as unmistakable as the solar 
modifications of magnetic phenomena, the analogies which have been 
pointed out, by Messrs. Baxendell and Bloxam between magnetic and 
pluvial and by myself between pluvial and auroral curves, are indicative 
of other possible lunar influences which are equally unmistakable. If the 
difficulty of conceiving an adequate cause for a supposed phenomenon were 
to deter us from inquiring whether an apparent dependence were real or 
illusory, all progress in science would become impossible. Finally, if it 
can be shown that solar rain-curves exhibit different, and often contra- 
dictory inflections, similar to those which are objected to in the lunar 
curves, and if a consistency of disagreement can be shown between the 
lunar results at two given stations, accompanied by a consistency of agree- 
ment between the results in different cycles at the same station, the ar- 
gument from apparent contradiction will be deprived of all its force. 
I have no hope of thoroughly convincing any one who is skeptical of 
lunar influence on the weather by deductions from observations at one 
or two, or a half dozen stations, but I believe that any one who will ex- 
amine, carefully and impartially, the tables I have already published, 
based on observations in India, Great Britain, Portugal, Canada and 
different portions of the United States, will at least be willing to admit
