52.577. 14 Metal Strips, after Arendt, Figure, of platinum, gold, lead, silver, copper, 

 German silver, brass, nickel, steel, iron, tin, zinc, aluminium and magnesium, of same 

 thickness, width and weight; lengths inversely proportional to specific gravity . . . 



The construction is very accurate and all metals are genuine. 



52.578. 3 Cylindrical Bodies of the same weight, after Kolbe, Figure, of aluminium, iron 

 and lead 



52.579. Cylindrical Glass Vessel with 4 Liquids of different specific gravity, Figure . . 



52.580. 6 Liquids of different specific gravities, Figure (Mercury, Sulphuric Acid, Glycerine, 

 Water, Petroleum, Sulphuric Ether), in glass tubes of same length and width, in wood 

 frame. The lengths of the liquid columns are in inverse ratio to the specific gravities 



Motion of Liquids. 



52.581. Outflow Apparatus, for experiments on flow out of an orifice in a thin wall, Figure 

 (W. D., Figs. 119, 120 [108, 109]), consisting of Mariotte flask, rubber tubing, glass 

 tube, outflow vessel, 1 mouthpiece and small table 



52.582. --idem, for experiments on outflow velocities at different pressures, Figure 



A sheet iron cylinder, 75 cm high, with a wide vessel at the top for more easily maintaining a 

 constant level, and with 3 orifices at distances of ratio 1:4:9 provided below the level, for showing 

 that the quantities flowing out are proportional to the square roots of the heights of pressure (Torri- 

 celli's Theorem). 



52.583. - - idem, after Weisbach, with vessel 1 m high, Figure, with stuffing boxes 

 (M. P. I, Fig. 402 [392]), on plate with levelling screws
