• These, and the tables of the wind previously detailed, we offer only as 

 approximations : for, with westerly winds especially, the difficulty of deter- 

 mining, at Malvern, whether it is a little to the north or south "of the due 

 west point is almost insurmountable. In the former case, according to the 

 sub-division before indicated (p. 223, vol. ii, of *' The Analyst^''^) the current 

 would be classed in the Dry, in the latter, in the Vapour column.
