Intra aram, quod loci aqua sustinetur, inest pnigeus uti infundibulum inversum, quem subter taxilli alti circiter digitorum ternm suppositi librant spatium imum una inter labra pnigeos et arae fundum.
Within the chest where the water is stored there is an air-vessel, like a funnel inverted; beneath this, small blocks about three inches high are placed, and they keep even the lowest space between the lips of the air-vessel and the bottom of the chest.
