the particles of magnetic bodies, ^c. 103 
at the time that any other formula would more closely repre¬ 
sent the observations, I considered to be a near approximation, 
and that consequently this value of p was correct: and as I 
wished to see how far the effects produced by the magnets 
revolving with their axes vertical, agreed with the effects when 
they revolved with their axes horizontal, and their poles at 
the same distances from the ring, I regulated the distances at 
which I observed, in the latter case, according to this value 
of p. This will account for the peculiar distances at which I 
made observations which might otherwise appear somewhat 
singular. The results which I obtained are arranged in the 
following table.
