The last column of the table contains the differences between the 
observation and the computation. Everything has been expressed in 
thousandth parts of the second.

The mean monthly results of the observations, together with the 
sinusoid by which they are represented, have been reproduced in 
fig. 6. 
In the second place we give, in the column O of the following 
table, the values of the supplementary inequality which we find in 
the mean, if we assume 00220 (t—10°) for the influence of the , 
temperature. These values are represented by a curve reproduced in 
fig. 7. The column O.—C. of the table contains the deviations from 
this curve.

As might have been expected, the curve shows clearly a half- 
yearly inequality.
