Dr, Herschel's Observations on the 
The following 50 positions have been calculated by the 
above tables, and belong to the several observations which are 
marked with the tabular letters of references, as has been 
explained in the 2d note, page 50. They have been computed to 
two places of decimals, but are only put down in degrees, as 
being sufficiently near for comparing them with the descrip- 
tions belonging to those parts of the belt which they point out.

I may venture to say, that there are not many of these cal- 
culated observations which do not very forcibly concur in 
proving the assigned revolution to be properly stated. I shall 
however only mention a few of the leading ones, and leave 
the rest to be looked over at leisure by those who wish to exa- 
mine the subject minutely. 
In observations previous to the 4th of December, no particu- 
lar attention had been given to the minutiae of the belts ; but 
we may suppose them, on the nth of November, to have been 
considerably distinct and uniform, to occasion their being no- 
ticed ; and this the calculation verifies. For the position A 
points out 201 degrees, as the situation which was on the
