Sept. 28, 1794. There is a dark {pot in the fun on. the 
following fide. It is certainly depreffed below the fhining 
atmofphere, arid has fhelving fides of {hining matter, which 
' rife up higher than the general furface, and are brighteft at 
the top. “The preceding fhelving fide is rendered almott in- 
vifible by the overhanging of the preceding elevations, while 
the following is very well expofed ; the fpot being apparently 
_ fuch in figure as denotes a circular form viewed in an oblique 
- direction, 
~ Near the following margin are many bright elevations, 
clofe to vifible deprefiions. The depreiied parts are lets 
bright than the common furface. 
The penumbra, as it is called, about this fpot, is a confi- 
derable plane, of lefs brightnefs than the common furtace, 
and feems to be as much deprefled below that furface as the 
{pot is below the plane. 
Hence, if the brightnefs of the fun is occafioned by the 
lucid atmofphere, the intenfity of the brightnefs muft be lefs 
where it is depreffed ; for light, being bait alt be 
_ the more intenfe the more it is deep. 
- O88. 12,1794. The whole furfaee of the fun is diverfified 
by shisquality in the elevation of the fhining atmofphere. The 
loweft parts are every where darkefi; and every little pit has 
_ the appearance of a more or lefs dark {pot. 
_ + A dark fpot, which is on th< preceding fide, is furrounded 
by very great inequalities in the elevation of the lucid atmo-» 
 fphere; and its depreffion below the fame is bounded by an 
_ immediate rifing of very bright light. > 
O08. 13,1794. The fpot in the fun Lobferved yefterday 
is drawn fo near the margin, that the elevated fide of the fol- 
_ lowing part of it hides all the black ground, and ftill leaves 
_ the cavity vifible, forthat the ceprefiion ‘of the black {pots, 
guid the elevation of the facule, are cqually evident. .
