3 NATURAL HISTORY. 



water and but one wine, yet it doth not dead the 

 motion. This separation of water and wine ap- 

 peareth to be made by weight ; for it must be of 

 bodies of unequal weight, or else it worketh not ; 

 and the heavier body must ever be in the upper 

 glass. But then note withal, that the water being 

 made pensile, and there being a great weight of 

 water in the belly of the glass, sustained by a small 

 pillar of water in the neck of the glass, it is that 

 which setteth the motion on work : for water and 

 wine in one glass, with long standing, will hardly 

 sever. 



16. This experiment would be extended from 

 mixtures of several liquors, to simple bodies which 

 consist of several similar parts : try it therefore with 

 brine or salt-water, and fresh-water ; placing the 

 salt-water, which is the heavier, in the upper glass ; 

 and see whether the fresh will come above. Try it 

 also with water thick sugared, and pure water ; and 

 see whether the water, which cometh above, will 

 lose its sweetness : for which purpose it were good 

 there were a little cock made in the belly of the 

 upper glass. 



Experiments in consort, touching judicious and accurate 

 infusions, both in liquors and air. 



17. In bodies containing fine spirits, which do 

 easily dissipate, when you make infusions, the rule 

 is, a short stay of the body in the liquor,, receiveth 

 the spirit ; and a longer stay confoundeth it ; because 

 it draweth forth the earthy part withal, which em-
