The use of i,/, r and constant elements is equivalent to the use of osculating elements for the 

 given date of observation.

COMPARISON OF THE REVISED WITH V. ZEIPEL'S ORIGINAL TABLES. 



It was originally planned to conclude the example with a least squares solution of the orbit 

 on the basis of the observations used by v. Zeipel for the same purpose, and to test conclusively 

 the relative value of the revised and v. Zeipel's original tables b}' representing recent observa- 

 tions with both sets of elements and tables. 



In the course of the computation doubt arose regarding the accuracy of some of the 

 observations selected by v. Zeipel, which led us to reject them and substitute other observa- 



> In the determination of the constant c use quantities in brackets.
