date Bauschinger's tables give the integrated values of the per- 

 turbations. I could thus take directly from his tables without 

 interpolation the values of the perturbations for the interval 

 between 1889 October 8.0 and 1896 October ii.o. 



The values of the perturbations as determined by my new com- 

 putation for this interval can be taken from my tables by inter- 

 polation. Interpolating thus and comparing my results with 

 those of Bauschinger, as taken directly from his tables, I find, 



The differences are all extremely small, with the exception of 

 JM. This is accounted for, however, by the difference in 

 methods : Bauschinger computed the perturbations in M di- 

 rectly, while I computed those of L, and the number given 

 above for my perturbation in M was found indirectly from the 

 values given in my tables for L and ~. 



Not only do the total results agree closely, but the agree- 

 ment for the separate planets is also marked, as is shown by the 

 following comparison of the perturbations of the mean motion. 



II. The perturbations thus found were applied and Elements 

 II were carried forward to 1903 and backward to 1889; the 

 following elements representing the appearance of 1903 :
