Representing by the same general expression as before (page [38]) the mean monthly temperature of evaporation at any hour, we find the following values of the constants. TABLE VIII. Values of the Constants in the Periodical Expression for the Mean Monthly Diurnal Inequalities of the Hygrographic Results, for the Year 1862. TABLE IX.
