These are corrections which should be applied to m of Srruvr- 
Peters. To obtain the corrections for Newcoms’s m the difference 
between the values for m Perers- Nrwcomes should he added. Newcomg *) 
gives the following values: 
Centennial precessional motion for 1850; 
m n 
PETERS-STRUVE 4607"63 2005"64 
Nrewcoms 1896 4607.11 2005.11 
(final value) 
From the differences Perers—N,, : 
in 7 + 0'52, 
in n + 0.53, 
it becomes evident that the values m and » of Srruve-Prrers do 
not correspond to one another, when we adopt the most probable 
value for the planetary precession. [ reduce my results therefore 
to Newcomps’s values:

The mean error is deduced from the comparison of the above 
8 values for Am with their mean.

from the preliminary solution. The results for 0.93 N then are:
