The movements of the barometer at Jacobabad are, as a rule, allow- 

 ing for difference of elevation, similar to those observed at Quetta, as 

 might be expected from the small difference of longitude between the 

 two stations, which is less than one hundred miles. Consequently, 

 Jacobabad might be substituted for Quetta in the above list, without 

 altering the order of the events, the barometric minima arriving at 

 Jacobabad before they arrive at Bickaneer. I give also the following 

 list of additional cases in which the barometric minima at Jacobabad 

 precede those at Bickaneer or Neemuch.

In almost all the instances in the above lists, confirmatory evidence 

 of a motion from west to east is obtainable from the observations re- 

 corded at other pairs of stations in "Western India. I find also the 

 following instances of eastward motion in earlier years, by comparing the 

 observations recorded at Kurrachee and Deesa.

The instance recorded at Kurrachee in 1858 was a very well marked 

 cyclonic depression of the barometer. Unfortunately, no observations 

 were recorded at Deesa on that occasion, but there is little doubt, that 

 the centre of the disturbance passed to the northward of Kurrachee 

 from west to east, for the wind was very strong from west at the time 

 of the minimum pressure, and veered to north as the barometer rose. 

 The Bombay barometer was but little disturbed. The isobaric charts
