attractions are exetted in oblique directions, the 
counterpoife is then entirély loft, fo ithat changes 
and confequent ‘precipitations will ‘readily foon 
follow.—It may not be improper ‘to obferve, in 
addition to the preceding remark, that if a fall con- 
tinues ‘during an eclipfe, .or at the ‘time of ‘the 
change.and full of the moon, itdhows ‘fuch-a great 
difpofition in the atmofphere ‘to precipitation, as 
to overcome: the fteadying ‘influence of ‘the ‘Sun and

weather inay be expected, as I'have often hitherto 
experienced. But in general, even when the 
weather is difpofed to precipitations, it fettles for 
twelve hours -before, and twenty-four ‘hours after 
the change and full of the moon. 
It:may, :perhaps,:be proper to make the following 
addition to the-firft part of the 15th. remark, viz, 
ahigh barometer is:always accompanied by moderate 
weather as to wind, and is followed in'the firt place 
by warmer weather than what-is the medium of the 
feafon ; -2dly. by fair weather without precipitations; 
3dly.:by calm or -moderate weather as to wind. ‘It 
is alfo worth remarking, that a ifteady and ‘firong . 
wind blowing fix hours or more ‘from the foutherly 
points, always drops the barometer, but from the 
northerly, always raifes it. | 
That a real decompofition, or‘lofs of fubftance ‘in 
the air, occurs in the time of great falls, appears 
highly probable, when in addition :to the pheno- 
mena narrated in remarks 23d.-and oath. ‘it -is
