Aug. 11, 1815. Thomas Forster. 



* There is something; pecalinr in the weather of late; the repeated pro- 

 cesses wliich threatened rain so often, arrested as it were before its fall, 

 and the steady state of the barometer, the great dryness, &c. indicate a pe- 

 culiar state of the air. People generally complain of an oppressive and 

 unhealthy feeling from a sort of closenesa in the air.
