If the North or South Poles of two Magnets be 
oppofed to each other, the Filings will exhibit the 
Appearance of two Streams meeting; and the 
Curves of each will all be turned towards the op- 
polite Pole of the fame Magnet. The Appearance 
is altogether the fame, whether the two North or 
two South Poles be oppofed to each other. So 
that it is not to be determined from any of thefe 
Experiments at which of the Poles the magnetic 
Stream enters. As we have feme Reafon to think 
it enters at the North Pole, we may fuppofe that 
the Cafe, without Danger of Errour ; provided we 
build nothing upon the Suppofition, but what would 
hold good {mutatis mutandis ) if the contrary ftiould 
be true. This being fuppofed, when the South 
Poles are oppofite, the two Streams coming out at 
them are dirediy contrary, whereby the magnetic 
Matter is accumulated, and therefore diverges fo 
much the fafler to return back to the North 
Poles. When the North Poles are oppofed to 
each other- the Streams of magnetic Matter re- 
turning from the South Poles are dirediy contrary; 
and by crouding at once towards each polar Surface 
are accumulated betwixt them, and converge to- 
wards them fo much the falter. 
Thefe five Experiments feem fufficient to cftablifii 
the Truth of the Propofition ; and many more might 
be produced to the fame Purpofe*
