many Phenomena eafily and plainly, that I 

 would not be thought to deny it. Keither 

 would I be thought wholly to reject my Bro- 

 thers Solution of this Problem } for certainly 

 that Motion (whatfoever it is) in a Men- 

 firuum, which is able to diflblve fuch a folid 

 Body as Iron, that is , which is able to di- 

 ftu'rb the clofe and ftrong Cohefion of the 

 Parts of Iron, may very well be fuppofed fuf- 

 ftcient to difturb or keep up thefe parts from 

 retting in the bottom of the Veflel, wherein 

 the folution was made: And certainly no 

 better account can poffibly be given of fuch 

 Solutions, than by fuppofing fuch an internal 

 motion in the parts of the Menfiruum infinu- 

 ating themfelves into the folid Body, and 

 loofening its parts. And tho' it may be ob- 

 jected, that in the parts of Water there may 

 be fuppofed as violent an internal motion, as 

 in the parts of Aqua-Fortis , and yet we fee 

 Water will not diflblve Iron as Aqua-Fortk 

 does, and common Bees- Wax is difturbed by 

 neither of them , I leave the nice enquiry 

 after this Point to others, vizi, What kind of 

 Motion and peculiar Conformation of parts 

 is requifite both in the Menfiruum and in the 

 difiblved Body, that a Solution may refalt 

 from their Commixture.
