than it is with us. Hence, the compression of the elastic gases 
of which the solar atmosphere consists, if similar to our owh, 
must be greater than that of ours, in proportion to the superior 
force by which they are compressed, namely, their own power- 
ful gravitation towards the sun. 
The Solar Atmosphere, like ours, is subject to Agitations , such as 
with us are occasioned by Winds. 
A proof of this may be drawn from the observations which 
have been given. In several instances, we have seen the plane- 
tary clouds move over the openings ; which could not have hap- 
pened, unless the atmosphere in which they floated had been 
considerably agitated. In many other instances, we have shewn 
that a strong bias existed in the direction of the cause which 
generates the shallows. This indeed is so evident, that I have 
hardly ever seen a single shallow which had not some excen- 
tricity ; the smallest segments of these shallows being always 
turned towards what I have called the quiescent side of the 
openings. To this may be added, that the continual luminous 
decompositions in the superior regions, and the consequent 
necessary regeneration of the atmospheric gases that serve to 
carry them on, and which probably are produced below the 
inferior cloudy regions, near the surface of the sun's body, must 
unavoidably be attended with great agitations, such as with us 
might even be called hurricanes. 
There is some clear Atmospheric Space, between the solid Body of 
the Sun and the lowest Region of the Clouds. 
From what has just now been said of the agitations which 
appear to take place in the solar atmosphere, it follows, that
