wind-movement from right to left , but F is of less energy 

 than its predecessor. This is shown by the curves being 

 easier and wider apart ; and, though the changes of wind are 

 of the same character as before at each place, they are of less 

 force, there being but very little pressure-movement at a, but 

 b falls to 29-80, and c to 29-70. The easterly progress of F 

 brings south-west winds, with increasing pressure, but as an 

 anticyclonic system is now approaching the wind remains 

 about south-west, and pressure continues to increase, at a 

 and b to 30*30, at c to 30-25. a has now been in high 

 pressure ever since E passed to the eastward of it, and the 

 continuance of the south-west winds at each position shows 

 that the maximum pressure of the second anticyclone passes 

 to the northward of them all. 



The following table shows the alterations of pressure at 

 each station (+ showing increase, — showing decrease) : —
