This apparatus is independent of a time observation. It has two upright tubes alongside each 

 other, which are horizontally bent underneath. One is for taking up the impart of flowing water, while 

 the other >hows the hydrostatic pressure of the surface of the water. 



Both tubes have a suction tube connected to them at their upper ends: this suction tuhe can 

 be closed by a cock. By this arrangement it is possible to raise or lower the \\ater < olumns, as re- 

 quired, for convenience in reading, for carrying out the comparison in height. 



The lower cock which cuts off the water columns from the lu)n> can lie closed and opened by ' 

 two cords.
