52.705. Apparatus after Schaffers, for Experiments with Gases and Vapours, Figure, s ' 

 suitable for proving Boyle's (Mariotte's) Law for Pressures which are greater or smaller 



than 1 atm. and for experiments on the Tensive Force of saturated and non-saturated 

 vapours in vacuo and in air (Ztschr. f. d. phys. u. chem. U. 18, 1905, p. 217) ... 6. 0. 



The apparatus is a combination of the Feilitzsch -Weinhold Apparatus for proving Mariotte's 

 Law with the 3-tube apparatus as used for the laws relative to the tensive force of gases and vapours.

 for demonstrating the Barometer, Mariotte's Law, the (Icissler Mercury Air Pump, the 

 Expansion of Air with constant volume and constant pressure respectively (Air Thermo- 

 meter), the Yolumnometer, the Tension of saturated and non-saturated vapours . . 5. 0.
