 arft. That the longer a fall has been indicated 
by f{treamers and a low barometer, not accompanied 
or followed by cold, without its taking place, the 
heavier and more continued it will be when it once 
commences. 
ged. That thunder is the confequence of a 
very fudden and thorough change or decompofition 
taking place in the lower regions of the atmofphere, 
and confequently, that an immediate precipitation 
or fall will enfue, if the thunder is near, or a 
fudden change of the temperature of ts air. to 
cold. 
23d. That the falling of the barometer may 
proceed from a decompofition of the atmofphere 
occurring around or near that part of the globe © 
where we are placed, which will occafion the elec- 
tricity of the atmofphere to be repelled upwards in 
fine lambent portions; or driven downwards or up- 
wards in more compacted balls of fire; or laftly, to 
be carried along with the rain, &c. in an impercep- 
tible manner to the furface of the earth: the pre- 
cipitation of the watery parts generally very foon 
takes place, which diminifhes the real gravity of 
the atmofphere, and alfo by the decompofition of 
fome of the more aétive parts, the air, lofes part 
of that elaftic and repulfive power which it fo 
eminently poffefled, and will therefore prefs with
