little broader at both ends where it is upon the turn round 
the globe. 
June 5. The planet Jupiter is not sufficiently high for 
distinct vision, and Saturn is already too low to use a proper 
magnifying power ; but nevertheless the difference in the 
formation of the two planets is evident. The equatorial as 
well as polar regions on Jupiter are more curved than those 
of Saturn. 
June 9. The air is beautifully clear, and proper for critical 
observations. 
The breadth of the ring is to the space between the ring 
and the body of Saturn as about 5 to 4. See Fig. 3. 
The ring appears to be sloping towards the body of the 
planet, and the inside edge of it is probably of a spherical or 
perhaps hyperbolical form. 
The shadow of the ring on the planet is broader on both 
sides than in the middle ; this is partly a consequence of the 
curvature of the ring which in the middle of its passage across 
the body hides more of the shadow in that place than at the 
sides. 
The shadow of the body upon the ring is a little broader 
at the north than the south, so as not to be parallel with the 
outline of the body; nor is it so broad at the north as to 
become square with the direction of the ring. 
The most northern dusky belt comes northwards on both 
sides as far as the middle of the breadth of the ring where it 
passes behind the body. It is curved towards the south in 
the middle. 
I viewed Jupiter, and compared its figure with that of 
Saturn. An evident difference in the formation of the two
