Figure , Climate , Atmosphere, and Ring of Saturn. 4,6$ 
south pole the. whole distance is of a pale whitish colour ; less 
bright than the white belts, and much less bright than the 
ring. 
This has been represented in a figure which was given in 
the volume of the Phil. Trans, for 1794,, page 32. It is to 
be noticed that the south pole of the planet had been long 
exposed to the influence of the sun, and the former polar 
whitishness was no longer to be seen. 
Jan. 1, 1794. The south polar regions are a little less bright 
than the equatorial belt. 
Nov. 5, 1796. The space between the quintuple belt and 
the northesn part of the ring is of a bright white colour. 
This seems to indicate that the whiteness of the northern 
hemisphere of Saturn increases when there is less illumination 
from the sun. 
May 6, 1806. The north pole of Saturn being now ex- 
posed to the sun, its regions have lost much of their bright- 
ness ; the space about the south pole has regained its former 
colour, and is brighter and whiter than the equatorial parts. 
May 15. The south polar regions of Saturn are white ; 
those of the north retain also some whitishness still. 
May 18. With a magnifying power of 527, the south 
polar regions remain very white. The equatorial parts be- 
come of a yellowish tinge, and about the north pole there is 
still a faint dusky white colour to be seen. 
June 3. The south polar regions are considerably brighter 
than those of the north. 
These observations contrasted with those which were made 
when the south pole was in view complete nearly half a
