52.481. Pascal's Apparatus, for showing that the pressure of liquids depends on their height 

 and the surface of the bottom of the columns and not upon the capacities of the vessels, 

 Figure, with triple tube, the parts of which can be shut off by cocks, with 3 bottom 

 pieces of different sizes 



52.482. Pascal's Apparatus, for showing that the pressure of liquids depends on their height 

 and the surface of the bottom of the columns and not upon the capacities of the vessels, 

 Figure, can also be used as a Hydrostatic Balance, on board with levelling screws, 

 with 3 tubes (M. P. I, Fig. 366 [360]) 



52.483. Hartl's Apparatus, for showing that the pressure of liquids depends on their height 

 and the surface of the bottom of the columns and not upon the capacities of the vessels, 

 with 3 different tubes. The height scale is fitted to the movable piston so that the 

 pressure-altitude and the magnitude of the pressure can be read off simultaneously (the 

 latter on the pointer of the balance) 



52.484. idem, with 3 different rams, with plane, concave and convex surfaces . . . 



52.485. Pellat's Apparatus, for showing that the pressure of liquids depends on their height 

 and the surface of the bottom of the columns, Figure (Ztschr. f. d. phys. u. chem. 

 TJ. 3, 1889/90, p. 55) 



The apparatus consists of a metal ring fitted to a massive stand, this ring being provided with 

 a cock and a closing membrane acting on a pointer lever. An adjustable pointer is fitted to a vertical 

 lever which permits of 3 differently shaped vessels, fitting the ring and pertaining to the apparatus, 

 to be filled to the same level. The piston is packed with mercury. 



52,487. Apparatus, for showing that the pressure of liquids depends on their height and the 

 surface of the bottom of the columns and not upon the rapacities of the vessels, witli 



Spring Balance after Zahlbruckner, F i g u r e, with 3 different tubes 



The spring balance is contained in a brass tube with plain, two-coloured scale and pointer; a
