Comparison of relative intensities hy the three methods — Continued. 



MAY 2. 



MAY 3. 



MAY 6. 



The above table shows phiinly the effect of temporary influences in modifying the observed 

 intensities, and also that the different instruments are differently affected by the same influences. 

 In order to eliminate the ac(;iden1al i)eculiarities and obtain a more reliable comparison of the 

 methods the following table has been computed. It combines the observations made at the same 

 hour on the different days, and uses tho.se times only at which observations on two or more days 

 were made.
