Table II. — Comparison of computed and observed solar intensities — Continued. 



MAY 2. 



MAY 3. 



In the above table the columns I, II, III of intensities and residuals refer to the first com- 

 putation, with the assumed values of A and p, the result of the first approximation, and the result 

 of the second approximation respectively. An examination of the last column of residuals shows 

 how nearly the second approximation represents the original observations. There are a few large 

 residuals, but on the whole the agreement is very satisfactory. 



The resulting values of the solar constant have been given in Table I, and show excellent 



agreement. Collecting them here, with the interval of time covered by the observations on each 



day, we have the following results : 



SOLAR CONSTANT. 



Mean of all, 2.347. 

 Mean of April 30 to May 2, 2.322.
