142 On the Nature and Conffrudiion 
Sepé. 16, 1794. The fun contains many large facule on 
the following fide of its equator, and alfo feveral on the pre-= _ 
ceding fide. I perceive none about the poles. They feem 
gencrally to accompany the fpots; and probably, as the fa- 
cule certainly are elevations, a great number of them may 
occafion neighbouring depreffions, that is to fay, dark fpots. 
+ The facula being dtevuaond! very fatisfactorily explains thé 
reafon why they difappear towards ‘the tniddle of the fun, and | 
re-appear on the other margin; for, about the place where 
we lofe them, they beein to be edge-ways to our view ; and 
iF between the facule thould lie dic fpots, they win! moft 
frequently break out in the middle of the fon, becaufe they 
are no longer covered by the fide-views of thefe facule. 
Sep. 22,1792. There are not many facule in the fun, 
and but few {pots ; the whole difk, however, is very much 
stieed with roughnels, like an orange. Some of the lowett 
parts of the inequalites are blackith. 
Sept. 23,1792. The following fide of the fun contains 
many facule near the limb. They take up an arch of about 
50 degrees. There are likewife fome on the preceding fide, 
The worth and fouth is rough as ufual, but differently dif- 
poled. The faeula are ridges of elevations above the vee 
furface. 7 i 4 
Feb. 23, 1794. Fy an experiment I have juft now tried, 
i find it confirmed that the fun cannot be fo diftinétly viewed 
with a fmall aperture and faint darkening elaffes, as with a 
Jarge aperture and {ttonger ones ; “hp jatar is the method F

One of the black fpots on the preceding margin, which 
was greatly below the furface of the fun, bad, next to it, a 
protuberant lunip of fhining matter, a little bn¢hter than the 
reft of the fun, 
About all the fpots, the fhining matter feems dota meca 
difturbed ; and is uneyen, lumpy, and zig-zagged in an it- 
regular manner. 
[call the fpots black, not that they are entirely fo, but 
merely to diftinoulfh them; for there is not one of them 
to-day, which is not partly, or entirely, covered over with.
