76 METEOROLOGICAL 



The utmost distance to which sea-water is 

 conveyed by teijipestuous winds is not easily 

 determined. Sir H. Davy, in his Elements of 

 Agricultural Chemistry, p. 295, states, that " in 

 great storms the spray of the sea has been car- 

 ried more than 60 miles from the shore," but he 

 does not give his authority. Being at Black wall, 

 in Derbyshire, the residence of my relative, John 

 Blackwall, Esq., on the 23rd of November, 

 1824, when a violent hurricane occurred which 

 did extensive damage on the southern coast, I 

 took several opportunities of examining the rain 

 which fell at intervals on that occasion, and 

 uniformly found that it became extremely turbid 

 on appUcation of the test, evidently containing 

 much more muriatic acid than rain collected in 

 large towns, during calm weather, is ever found 

 to contain. The storm commenced on the night 

 of the 22nd of November, and continued, with 

 httle abatement, till after noon on the 23rd. The 

 wind blew from the south all the time, and the 

 place of observation is 140 or 150 miles from 

 the sea in that direction. This is, perhaps, the 

 greatest distance on record, to which sea-water 

 has been clearly ascertained to be conveyed by 

 the wind ; and that it extended much further is 

 highly probable.
