Having thus completed the tabular data, | computed the normal per- 
centages from the fourth successive means, in accordance with the gene- 
ral plan of my previous meteorological papers. The resemblance be- 
tween the lake curve and the two interior curves is more striking, and 
the lake influence is less marked than I anticipated ; the opposition be- 
tween the Pacific and interior curves exhibits the effects of differences of 
temperature between polar and equatorial currents, in the air and ocean, 
at opposite seasons ; the differences between the Atlantic, the Pacific, the 
Gulf, and the land curves, are quite as striking as any of the differences 
between the curves of Junar-monthly rainfall at different stations ; and a 
larger proportion of the solur than of the lunar influence is disguised, by 
aggregating the accompanying six sets of solar normals, and the seven 
sets of lunar normals in the foregoing communication,
