the four stations, Buncranca, Killybegs, Killough, and Westport ; the correc- 

 tions inferred from a comparison of the results being, at these stations, con- 

 siderably greater than those deduced by a comparison of the instruments. This 

 may possibly be due, in part, to the entrance of air into the barometer tubes; 

 but there seems reason to apprehend that the discrepancy may be also partly 

 due to errors of observation, and that of a systematic kind, — the observers at 

 the foregoing stations, having shown less aptitude than others for this kind of 

 duty. Under the circumstances, the corrections deduced by the latter method 

 seem the more reliable. They have accordingly been applied to all the selected 

 observations hereafter discussed. 



Applying the foregoing corrections to the results of Table xiv., we obtain 

 the numbers of the following Table : —

In order to perceive more clearly the simultaneous variations in the distri- 

 bution of pressure, I have, in the following Table, combined the stations, and 

 their results as given above, into four groups, as hereafter described in treating 

 of the observations of wind-force. These are the following : —
