4^2 Dr. Herschel’s Observations and Remarks on the 
ever a very little too short ; it should have been to the polar 
diameter as 35,4,1 to 32, which is the proportion that was 
ascertained in 1789, from which I have hitherto found no 
reason to depart. 
The following particulars remain as my last year’s obser- 
vations have established them.

The flattening at the poles of Saturn is more extensive 
than it is on the planet Jupiter. The curvature in high lati- 
tudes is also greater than on that planet. At the equator, on 
the contrary, the curvature is rather less than it is on Jupiter. 
Upon the whole, therefore, the shape of the globe of 
Saturn is not such as a rotatory motion alone could have 
given it. 
I see the quintuple belt, the division of the ring, a very 
narrow shadow of the ring across the body, and another 
broader shadow of the body upon the following part of the 
ring ; and unless all these particulars are very distinctly 
visible we cannot expect that our instrument should show the 
outlines of the planet sufficiently well to perceive its peculiar 
formation. 
May 16, io h 10'. The greatest curvature on the disk of 
Saturn seems to be in a latitude of about 40 degrees. 
May 18. The difference between the equatorial and polar 
diameters appears to be a little less than the measures taken 
September 14, 1789, give it; but as the eye was then in the 
plane of the equator, and is now about 16' degrees elevated 
above it, we cannot expect to see it quite so much flattened 
at present. 
June 3. The shadow of the ring falls upon the body of the 
planet southwards of the ring, towards the limb ; it grows a
