 iiltcring stone B is suspended in the cistern by a ring around 

 the inside of it, which catches the projecting part of the 

 stone; the water in the cistern filters through into the 

 stone. D is a siphon, which conveys the filtered water 

 from the inside of the stone into a cistern E, which is

 the water are deposited in the bottom of the cistern A, in., 

 stead of beitig left in the bottom of the stone as in the 

 usual mode.
