Some further Experiments relating to the 
general Phenomena of Magnetifm, by the 
fame . 
Read Dec, HE Caufe of the furpming *Ph<eno- 
*747- mena of the Loadtione has hitherto 
efcaped our Knowledge, though diligently inquired 
after by Men of the Abilities. Such a Difcovery is not 
to be made without long Experience, and a great Va- 
riety of Fads : And the Nature of the Subjed is fuch, 
that the more Fads we are acquainted with, the more 
we find ourfelves perplexed. The Conclufions we 
draw from feme Experiments are feemingly contra* 
dided by others: and yetthefe feeming Contradidions 
are oft-times very reconcileable upon further Expe- 
rience. If what I am about to lay before the Society 
will in any-wife contribute to remove thefe Diffi- 
culties, I am in Hopes it will not be unacceptable, 
though I fhould not fo properly explain the Nature 
of the Caufe, as the Manner in which it ads. 
Many of thefe Experiments are not altogether new* 
but have not been fo much attended to as they 
leem to deferve.
