 der Sonnenfinsterniss am 5. Sept. 1793: »Not having for se- 

 veral days before, and likewise on the very day of the eclipse, 

 noticed any spols on the disk of the sun, three small ones 

 only excepted, which were pereeived on the 29 ,h of August; 

 and it appearing very remarkable to ine that, with this parti- 

 cular modification of the atmosphere of the sun , none of ils 

 blazing spots should be perceptible; I confess I was not a 

 liltle surprised on viewing the sun's disk with my large reflec- 

 tor, to find that no, either dark or blazing, spots appeared 

 on the luminous part, but that the whole visible disk was in 

 a manner marbled , or covered over with whitish , more or 

 less faint, nebuliosities ; as I had in deed seen it some years 

 ago with my 7-feet Herschelian telescope , but by far not in 

 so striking a- degree. I at the same lime discovered . west- 

 ward towards the rim* of the sun , a very small but distinet 

 blackish spot, which other observers with inferior telescopes 

 may well not have noticed, since I myself could not sce it 

 with my 7-feet Schraderian reflector. « Vol. 85. (1795.) Her-
