292 Dr. Herschel’s Observations to investigate 
With low magnifying Powers, Indentations will appear like 
Points. 
Feb. 4, 1800. I tried a magnifying power of only 45 times, 
and the sun then appeared punctulated, instead of indented. 
The points, or rather darker coloured places in the punctula- 
tions, were of different figures; few of them being round. 
OF PORES. 
The low Places of Indentations are Pores f 
Dec. 20, 1794. The lowest parts of the indented appearances, 
are almost dark and depressed enough to be called very minute 
openings. 
Pores increase sometimes , and become Openings. 
Feb. 10, 1800. Two indentations, observed an hour ago, are 
increased, and contain large pores, as if they were going to be 
converted into visible openings, like the indentations of three 
neighbouring corrugations mentioned under a former article. 
Jan. 22, 1800. Between some large and small openings were 
two pores, that grew darker while I looked at them, and may 
now be taken for very small openings. This seems to trace the 
openings to their origin, and perfectly connects the pores with 
them. 
Pores vanish quickly. 
Dec. 27, 1800. A small pore, that was north-following a 
very small opening, which served me as a direction for finding 
it again, i h 30' ago, is no longer to be seen.
