gar ding the Repulfive Force of Elefirical 
Bodies ; communicated in a Letter from 
Gran vile Wheler, F. R. S. to Crom-

SIR, 
T H E following Experiments I made in the Au- 
tumn of the Year 1732. and repeated them to 
Mr. Grey the following Summer, when he came into 
the Country. I had then Thoughts of communi- 
cating them to you through his Hands, to whom 
they owe their Being, and drew them up with a 
Letter to him prefixed : But, unwilling to be an Au- 
thor, I deferred the Corfimunication from time to 
time, till the fccond Summer came, when I was in- 
formed, that Mr. Dufay had written a Letter to his 
Grace the Duke of Richmond, dated Dec. 27. 1733.* 
wherein he takes Notice of the fame Solution of the 
Repulfive Force, a Copy of which Letter I received 
the September following, inclofed in one from Mr. 
Grey. All Thoughts of publifhing them were then 
laid afide, but meeting fome time fince with, a fuller 
Account of them in the Memoirs of the Academy of 
Sciences for the Year 1735. by which it appeared 
Mr. Dufays Experiments were not the fame with 
my own, aiiti having fince received the Commands 
of our worthy Prefident to communicate them, I 
take the Liberty at laft of fending them to you, as 
I intended they fhould have pafled through Mr. Greys
