He therefore regards an arrangement according to sidereal time 
not recompensatorj and from a proof taken by shifting of the monthly 
means he concludes: 
“Immerhin konnen wir aber aus den angefuhrten Werten ent- 
nehmen, dass die Amplitude einer etwa vorhandenen Sternzeitwelle 
nur sehr gering sein kann”.

In consequence of this discussion we can remark: 1. that for an 
accurate calculation of the sidereal tides an arrangement according 
to sidereal time, proper or improper, is unnecessary, so that little 
trouble is attached to it, and 2 that the influence of those sidereal 
tides cannot be so insignificant. 
Besides the sidereal-time solar-lunar tide proper K x also the solar tide 
P appears which moves with respect to the mean solar time in the 
same way as sidereal time but in an opposite sense. 
The angular velocity of K x is: 
15° -f 0°.04107 an hour 
that of P: 
15° - 0°.04107 „
