_ daily motion we compute the movement from the observation of 
Oct. 1, 1847, to that of Oct. 28, 1851, we shall find it to amount 
to 358 revolutions and 112 degrees. Supposing the number of 
revolutions to have been exacily 358, we obtain a daily motion ~ 
of 86°°612, which corresponds to one revolution in 4:15634 days. 
The following are Struve’s observations of an interior satellite, 
copied from No. 623 of the Astronomische Nachrichten. The 
es to which the letter E is annexed, were estimated by
