1826-7. ^Ex. 48-9.] SIR HUMPHRY DAVY. 391 



of the discoveries of Faraday, and he sent a paper to the 

 Koyal Society on the ' Application of Liquids Formed 

 by the Condensation of (rases as Mechanical Agents.' 



In 1823 he began to work on the defence of the 

 copper sheathing of ships, and in 1824 he had two 

 papers published on this subject. He went in a Govern- 

 ment steamboat to Norway, Sweden, and Denmark for 

 the purpose of trying the influence of motion on his 

 protectors. He had already suffered for a year at this 

 time from ill health. In 1825 his paper on the 'Pre- 

 servation of Metals by Electrochemistry' was published. 

 In practice his plan failed, and he was too ill to bear 

 lightly the disappointment of his expectations. In 

 1826 he had a paper read on the ' Relations of Electrical 

 and Chemical Changes.' It contained but little new 

 matter. On November 30 he was elected President of 

 the Royal Society for the last time. He was danger- 

 ously ill on the day of election. 



In the middle of December 1826 he was struck with 

 paralysis of the right side. 



With the restlessness of disease on January 22, about 

 a month after his attack, he set out for Italy. He had 

 the worst possible journey across Mont Cenis, and, after 

 being three weeks at Ravenna, in the middle of March 

 he wrote to Mr. Poole': 



I am, thank God, better, but still very weak and wholly 

 unfit for any kind of business and study. I have, however, 

 considerably recovered the use of all the limbs that were 

 affected, and, as my amendment has been slow and gradual, 

 I hope in time it may be complete. But I am leading the 

 life of an anchorite, obliged to abstain from flesh, wine, 

 business, study, experiments, and all things that I love ;
