tion, by mixing an Alkaly with an Acid feems 

 to contradift this ; for thereby the Fluidity 

 of the Menfiruum is not taken away, and 

 confequently, the internal Agitation of its 

 Parts is not diminifhed, and yet thereupon, 

 the Particles of the diflblved Body precipi- 

 tate all to the Bottom. To this he anfwers 

 in the forecited Article of January ^ that all 

 Mixtures of different Liquors introduce in 

 each a different Conformation of Pores, and 

 therefore the Infuiion of a new Liquor, drives 

 the infefible Parts of the diflblved Body from 

 their Places, and forces them to ftrike a- 

 gainft each other, and cling together, and 

 fo becoming more big and heavier tha. for- 

 merly, the internal Agitation of the Liquor 

 is no longer able to move and fuftain them, 

 and confequently they fall to the Bottom. 



This, as fairly and (hortly as I can propofe 

 it, is his Sentiment of this Phenomenon. 



But I conceive an other Account may be 

 given of this Appearance, and that the fore- 

 laid Law of Hydrofiaticks is a little deficient. 

 ? Tis true indeed, if we confider only the fpe- 

 cifick Gravity of a Liquor, and the Ipecifick 

 Gravity of a folid Particle floating therein, 

 the forementioned Rule is exacl ; but in 

 linking there is requifite a reparation of the 

 Parts of the Liquor by the finking Body ; and 

 there being a natural Inclination in the Parts 

 of all Liquors to Union arifing from an A- 

 greement or Congruity of their Parts, there 

 is a refinance therein to any thing that fe- 

 parates this Conjunction : Now unlefs a Bo- 

 dy have weight enough to overcome this 

 Congruity or Union of Parts, fiich a Body
