any appreciable lunar or planetary influence upon rainfall or other atmo- 
spheric phenomena, is based on the different, and sometimes contradictory, 
results obtained by different investigators, from observations in different 
places and at different times; another arises from the difficulty of con- 
ceiving any tidal or other force adequate for the production of any con- 
siderable disturbance. Nevertheless, such of the objectors as are familiar 
with Howard’s discussion of the moon’s influence upon the barometer; 
Sabine’s, of lunar disturbances of terrestrial magnetism; or Schwabe’s and 
Wolf’s, of the dependence of sun-spots upon planetary configurations, 
seem to admit—at least I am not aware that any of them deny—the prob- 
ability of the conclusions which those eminent observers have severally 
expressed. 
If it is conceivable that Saturn, Jupiter and Venis can in any way 
affect the cloudiness, or arnount of spotted surface of the the sun, not- 
withstanding the immense preponderance of his attractive, magnetic and 
other supposable forces, it is surely much more easy to imagine that they 
may similarly affect the meteorologic phenomena of the earth, which op- 
poses an antagonizing mass only 574.55 (according to Newcomb’s esti- 
mate) as great as that of the sun. If the lunar tides of our atmosphere 
are of sufficient magnitude to affect the barometer, the consequent waves 
must effect a blending of aerial currents of different temperatures and
