filtred be longer, and confequcntly heavier, then that which ri- 

 fcth; it muft needs raife the other upwards,and fall it fclf down- 

 wards. Now the raifing of the other, implieth lifting more wa- 

 ter from the ciftern,and the flidingofit fclf further downwards, 

 is the caufeofits converting into drops. So that the water in the 

 ciftern fcrvcth like the flax upon a diftaflfe, and is fpun into a 

 thrid of water, flill as it cometh to the flannen by the drawing 

 it up,occafioned by the overweight of the thrid on the other fide 

 of the center. 



Which toexprefle better by a fimilitudc in a folidebody:! re- 

 member I hare oftentimes feen in a Mercers fhop, a great heap 

 of mafly gold lace lie upon their ftall;and a little way above it a 

 round fmooth pin of wood, over which they ufcto hale their 

 lace when they wind it into bottomes.Now over this pin, I have 

 put one end of thclace^and as long as it hung no lower then the 

 board upon which the reft of the lace did lie,it ftirred not; for as 

 the weight of the loofe end carried it one way, fo the weight of 

 the other fide where the whole was, drew it the other way, and 

 in this manner kept it inequiJibrity. But as foon as I drew on 

 the hanging end to be heavier then the climbing fide (for no 

 more weigheth then is in the aire, that which lieth upon the 

 board, having another center) then it began to roulc to the 

 ground: and ftill drew up new parts of that which lay upon the 

 board,untillall was tumbled down upon thefloore. In the fame 

 mandcr it hapneth to the water ; in which, the thrid of it upon 

 the filter is to be compared fitly unto that part of the lace which 

 hung upon the pin;and the whole quantity in the ciftern, is like 

 the bulk of lace upon the fliopboard ; for as faft as the filcer 

 draweth it up, it is converted into a thrid like that which is al- 

 ready upon the filter : in like manner as the wheel converteth 

 the flax into yarn, as faft as it draweth it out from the diftaffc.
