each other, they approached in the ufual manner, as if fey 

 fomc mutual intiucnce. This was expected. 



'X. The larger hall was iluck on a piece of wire, and was 

 holden near the liualler one, which was floating uhllft this 

 (the larger one) was entirely out of the water. There w-asj 

 under theie circumflanccs, not any apparent attraftion what- 

 ever. 



3. The larcrer ball on the wire was then tolallv immerfed 

 in the water, and, though near the other ball, there was not 

 any apparent attraftion. 



4. The ball on the wire was then ra i fed ^rt?'//)' above the 

 furiace of the water near the floating ball; then the huall 

 ball approached, and the ufual appearance of attraction took 

 place. 



The following is offered as an explanation of the above 

 fa6^s; and is fuppofcd to be the chief, if not entire caufe, of 

 thofe efiecls : 



Round each cork ball, when floating on water, may be 

 feen an elevated circular n}afs of water, raifed probably from 

 the fame caufe (whatever that may be) by which water rifes 

 in bread, fugar, &c. : now it appears that when thefe two 

 circular mafles or rings of water touch each other they unite, 

 and, by endeavouring to form one mais, carry the two cork 

 balls with them until they touch.
