Biographical Account of Sir Humphry Davy, Bart. 



( Concluded from page 93.^ 



The week after the paper respecting the rotations of 

 the electro magnetic wire was read, Davy communicated 

 to the Royal Society a paper by Mr. Faraday, ** on Fluid 

 Chlorine." This was followed by a successful attempt at 

 liquifying several gases. The idea appears to have been 

 suggested by Davy ; but to all who are acquainted with the 

 ingenuity of Mr. Faraday, there can be little doubt that 

 the suggestion to him was the utmost that was requisite. 

 He succeeded in condensing sulphurous and sulphuretted 

 hydrogen, carbonic acid, euchlorine, nitrous oxide, cyan- 

 ogen and ammonia. 



In July, 1823, Sir Humphry made an excursion into 

 Ireland and Scotland, in company with Dr. Wollaston, 

 who also had acquired a taste for fishing, though at a late 

 period of his life. 



From 1823 to 1826, he presented the following papers to 

 the Royal Society :— " On the corrosion of copper sheeting 

 by sea water, and on the methods of preventing this effect ; 

 and on their application to ships of war and other ships." 



" Additional experiments and observations on the appli- 

 cation of electrical combinations to the preservation of 

 copper sheathing of ships and to other purposes." 



*' Further observations on the preservation of metals by 

 electro chemical means."
