§ 13. Measurements with higher pressure at 20 and 15.6. 
The constant temperature water from the thermostate is equally 
divided between the water baths round b, and f,, the difference in 
temperature of the baths thus remaining usually below 0.02 deg. 
The pressure is gradually raised to the required value and t e 
pressure and temperature kept constant for at least an hour before 
the beginning of the measurements. 
The steel capillary is protected in the manner described in § 8 
and its temperature ¢,; determined by three thermometers. If we 
consider that an uncertainty may remain in the mean temperature
