I Bo On the floating of Cork Balls, 



In all the experiments, the water which fur- 

 rounds the balls is elevated by capillary attrac- 

 tion, as alfo by the fide of the containing velTel, 

 except in experiment III. 



Experiment VI. Pieces of dry cork, or 

 painted balls, placed gently on water, and near 

 each other, alfo approach each other j but if 

 one is placed near the fide of the containing 

 veffel, adjoining to which the water is elevated, 

 it will recede. 



In this experiment the furrounding fluid is 

 depreflTed. 



Whether thefc bodies attraft each other, or 

 not, I prefume is not to be determined by thefe 

 experiments ; however they are not intended to 

 difprove any attraction, but rather to prove that 

 there is fome other more powerful caufe on 

 which the phenomena depend : if not, why does 

 the ball in the third experiment leave the fide, 

 to which it adhered in the firft; or how ftiali 

 we account for the univerfal recefs of balls 

 around which the fluid is deprefled, from thofe 

 around which it is elevated -, and why are they 

 not attrafted by bodies exceedingly near, when 

 thefe bodies are perfedly covered with water ? 



Thefe experiments I know are not of fuffici- 

 ent weight with fome who rank high amongfl 

 the literati, to prove that the phenomena are 

 not owing to attraftion ; yet I prefume the true 

 caufe has- long fince been explained upon hydro- 



ftatical
