Finally we obtain Table XI which contains the quantities obtained 
by the measurements and which are required together with Table II 
for the calculation by formula (7). The pressure of the gas in the 
manometer is given by pand the pressure difference between this 
and the meniscus in the piezometer corrected for capillary depression 
(see also § 5) by &,. 
For the measurements at ordinary temperature i. e. at 15.°6 and 
20°.0 C. we may put Z = tj, when (7) is simplified and reduces to

1) The difference between the values of the pressure now given and those in the Dutch 
text, is due to improved calculations of the calibrations and corrections see Comm. n° 78c.
