yet withal they cast up some spissitude : and this 

 instance is to be referred to separation. 



306. On the other side it were good to try, what 

 the adding to the liquor more lees than his own will 

 work ; for though the lees do make the liquor turbid, 

 yet they refine the spirits. Take therefore a vessel 

 of new beer, and take another vessel of new beer, 

 and rack the one vessel from the lees, and pour the 

 lees of the racked vessel into the unracked vessel, and 

 see the effect : this instance is referred to the refin

 lerate the clarification, by opening the body of the 

 beer, and cutting the grosser parts, whereby they 

 may fall down into lees. And this instance again is 

 referred to separation. 



308. The longer malt or herbs, or the like, are 

 infused in liquor, the more thick and troubled the 

 liquor is ; but the longer they be decocted in the 

 liquor, the clearer it is. The reason is plain, because 

 in infusion, the longer it is, the greater is the part 

 of the gross body that goeth into the liquor : but in

 infuse, and then to take off the liquor and decoct it ; 

 as they do in beer, which hath malt first infused in

 This also is referred to separation.
