With respect to the remarkable increase of brightness 
indicated by the observations, I may observe that from the 
care taken in making the comparisons with the Milky Way, 
and in noting the state of the atmosphere at the times of 
observation, I have no doubt of its reality. 
Mr. Long, F.R.A.S., exhibited a sketch of Jupiter, as 
seen on February 29th, at 7’* 45“ Greenwich mean time, 
showing a small dark spot near the middle of the large dark 
belt, and a curious streak or belt below the centre of the disc, 
lying in a direction very considerably inclined to that of the 
ordinary belts. 
Mr. Williamson exhibited two photographs of the Sun, 
one of which had been taken a few hours before the meeting 
of the Section. 
Since Mr. Long drew attention to the curious oblique 
streak on Jupiter, Mr. Baxendell has twice observed it with 
the instruments of Mr. Worthington’s Observatory, and 
sketches of its appearance are given in figures 2 and 3 of the 
annexed plate, from which it will be seen that considerable 
changes have taken place since Mr. Long’s observation of 
February 29.
