sponds to their density when they rest in eguilibrio in a gaseous 
fluid of their own specific gravity. We do not wish either to 
accept or to reject this hypothesis, but would frame the follow- 
Ing statement, which also includes this view of the ease: Solar 
facule consist of solid or liquid bodies of a greater or less magnitude, 
either slowly sinking or suspended in cequilibrio in a gaseous medium. 
5. In connection with this part of our subject it will be well 
. to investigate the relative position of spots and their aceompa- 
nying facule;. and this is ae in the following table for all the 
ew pictures available for this purpose.

26. It appears from the result of table 11, that out of 1137 
cases 584 have their facul either entirely or mostly on the left, 
while 508 have it nearly equally on both sides, and only 45 
mostly on the right. Hence we see that facule are on an aver- 
ee of substances, such as iron, which are condensed into the ~ 
iquid or solid state at a sce combed high temperature. Now 
at in the sun’s photosphere we 
hae ae ar 
agine that such vapors are seldom or never condensed, and that 
what My really see is an incandescent plain underlying these 
Vapors
