These give the following values for the corrections of the elements: 
AM = — 2".6793 
Ai=+ 9.29 
AS = — 40 .78 
By means of substitution in the equations of condition we find 
that these corrections leave the following errors O—C in the obser- 
vations : 
1906 Aug. 28.55 Ac=—0.190 Ad=—O"A4 
Sept. 25.51 0,205 40573 
Oct. 10.35 00 906

The now found corrections of the elements do not differ considerably 
from those determined before, but a comparison of the remaining - 
errors shows that the introduction of the uncertain fourth place in 
the calculation cannot be said to have improved matters. Therefore 
I continue to regard the elements given at the beginning of this 
paper and agreeing absolutely with those from the “Proceedings” of 
Nov. 1906, as the most accurate for the present moment. 
For the approaching return of the comet I have kept these ele- 
ments unaltered since there was no time to calculate the pertur- 
bations. I have only reduced the elements 2, a and Jv to the ecliptic 
and the aequinox of 1912.0. So the employed elements are : 
Epoch 1912 June 15.0 M. T. Greenw. 
M = 328°25'19".269 
uw = 517".447665 
T — 1913 January 20.695 M. T. Gr. 
log a = 0.557427 
p= 24°20'25".6 
i= 2049 33 | 
x= 3846 732.9 f 1912.0 
Sh = 331 4942 1 
According to these elements circumstances are not quite so favour- 
able this time. The perihelion passage occurs shortly before the con-
