The air rushed in through the opening P. The stop-cock T2 was then closed simultaneously with the stopping of the stop-watch when the liquid in the viscometer just crossed the upper mark. [...] From the erratic nature of the times it was thought that the cause lay in (i) improper adjustment of pressure (negative) in B (ii) unequal temperature in the various parts of the tube E. D. dissolution of glass by water or solutions (iv) drying of the inner walls of the viscometer bulb E. Any or all the above causes may be the reason for the observed discovery in the times of rise. [...] The drying of the inner walls of the viscometer bulb cannot be the cause of the discrepancy because the air which enters the bulb during the flow out of the liquid is saturated with the vapours of the water (or test solution) kept in tube F. It appeared therefore that the main cause was (ii). [...] Even though the whole arrangement was kept in the set thermostat for about an hour before taking the readings it is no guarantee that inside the tube and above the level of the expermental solution the temperature of the air and hence that of the vicometer bulb was the same as that of the thermostat. [...] In the second place the evaporation of the water in the aspirator under the diminished pressure causes distubance which is bound to affect the maintenance of the constancy of the pressure.
