According to all of these observations, the elastic force of the vapor 
of the air has one daily maximum and one daily minimum.

The minimum pressure of the vapor occurs at almost the precise 
instant of minimum temperature, and so also with the maxima. 
The pressure of the gaseous atmosphere has one daily maximum at 
Catherinenburg about 8 p. M. and one daily minimum at 10 a. M., ant 
the motion is throughout extremely regular. At the other three sta- 
tions there is a maximum about the time of greatest cold, and a mini- 
mum | about the time of greatest heat; but there are also subordinate 
and minima. Possibly the direction of the wind may have 
some influence in producing these irregularities.
