the two lately discovered celestial Bodies . 
Of the Appearances of the new Stars, with regard to a Disk. 
Feb. 7. Ceres, with a magnifying power of 51 6±, shews an 
ill defined planetary disk, hardly to be distinguished from the 
surrounding haziness. 
Feb. 13. Ceres has a visible disk. 
April 22. In viewing Pallas, I cannot, with the utmost atten- 
tion, and under the most favourable present circumstances, 
perceive any sharp termination which might denote a disk ; it 
is rather what I would call a nucleus. 
April 28. In the finder, Pallas is less than Ceres. It is also 
rather less than when I first saw it. 
Of the Appearances of the new Stars, with regard to an 
Atmosphere, or Coma. 
April 2i.I viewed Ceres for nearly an hour together. There 
was a haziness about it, resembling a faint coma, which was, 
however, easily to be distinguished from the body. 
April 22. I see the disk of Ceres better defined, and smaller, 
than I did last night. There does not seem to be any coma ; 
and I am inclined to ascribe the appearance of last night to a 
deception, as I now and then, with long attention, saw it 
without; at which times, it was always best defined, and 
smallest. 
April 28. Ceres is surrounded with a strong haziness. 
Power 530. 
With 51% which is a better glass, the breadth of the coma 
beyond the disk may amount to the extent of a diameter of the 
disk, which is not very sharply defined. Were the whole coma 
and star taken together, they would be at least three times as 
MDcccir. g g
