 Robert Christison's inquiries over the whole of Scotland, on a

 Highland and Agricultural Societies, and under Sir Robert's super-

 appeared to cause fine dry weather on the west coast when the 

 Edinburgh side of the island was under the domain of ram and 

 easterly haars. 



Sir R. Christison hoped that such an extended series of obser-
