zations, to be as completely subject to ascertainable laws as are the mo- 
tions of the heavenly bodies. 
About a year ago, I showed, by my discussions of the Lisbon rainfall 
(ante pp. 178-190), that it is possible, uuder favorable circumstances, to 
obtain satisfactory evidence of lunar influence upon the weather, even 
from a comparison of the rainfall in different cycles of less than six 
years’ average duration. My subsequent discussion of the monthly 
means of Tennent’s San Francisco observations (Journal of the Franklin 
Institute, lxiii. 204-6), led me to hazard certain predictions relative to the 
tidal rains on the opposite shores of continents, and the influence of 
opposite winds, or of upper and lower tidal currents. Mr. Tennent has 
gcnerously furnished me a copy of his'daily observations on the rainfall, 
which so fully corroborate the first and third of those predictions, that I 
hope to obtain from him an equally complete record of the direction of 
the wind, in order to have the requisite data for similarly testing the 
other two. Governor Rawson W. Rawson, C. B., has also kindly con- 
sented to provide me with a transcript of observations at Barbados, a sta- 
tion within the belt of the trade winds, and, therefore, favorably situated 
for such comparisons with the San Francisco observations as may serve
