REPORT OF THE 
the predicted appearance of Jupiter devoid of his Satellites, a 
phenomenon which hitherto had in its recurrence been very 
little known or noticed. The second Satellite was eclipsed by 
Jupiter, the other three, preceded by their shadows, were seen 
traversing his disk as dark spots. This phenomenon had 
hitherto almost entbely escaped notice. Only five observers 
are recorded to have seen it in former years ; among them. Sir 
W. Herschell, May 23, 1802; Dawes and Grriesbach, Sept. 27, 
1843.
