The Institute of France gave Davy the Napoleon Prize of three thousand francs for the best experiments in galvanism.  Dublin, in 1810, paid Davy four hundred guineas for some lectures upon his discoveries.  The Farming Society of Ireland gave him 750 pounds for six lectures on chemistry applied to agriculture.  In the following year he received more than a thousand pounds for two courses of lectures at Dublin, and was sent home with the honorary degree of LL.D.  In April, 1812, he was knighted, resigned his professorship at the Royal Institution, and “in order more strongly to mark the high sense of his merits” he was elected Honorary Professor of Chemistry.  In the same month Davy married a young and rich widow, who had charmed all Edinburgh by her beauty and her wit.  Two months after marriage Sir Humphry Davy dedicated to his wife his “Elements of Chemical Philosophy.”  In March, 1813, he published his “Elements of Agricultural Chemistry.”  He travelled abroad, and was received with honour by the chief men of science in all places that he visited.  When, at Pavia, he first met Volta:  he found that Volta had put on full-dress to receive him.

In August, 1815, Davy’s attention was drawn to the loss of life by explosions of fire-damp, and by the end of the year he had devised his safety-lamp.  The coal owners subscribed 1,500 pounds for a testimonial, gave him also a dinner and a service of plate.  In October, 1818, he was made a baronet.  In November, 1820, he was elected President of the Royal Society.

His next researches were chiefly on electro-magnetism and the protection of the copper sheathing on ships’ bottoms.  At the end of 1826 his health failed seriously.  He went to Italy; resigned, in July, 1827, the Presidency of the Royal Society; came back to England, longing for “the fresh air of the mountains;” wrote and published his “Salmonia, or Days of Fly-fishing.”  In the spring of 1828 he left England again.  He was at Rome in the winter of 1829, still engaged in quiet research, and it was then that he wrote his “Consolations in Travel; or, the Last Days of a Philosopher.”  His wife, who shone in London society, did not go with him upon this last journey, but travelled day and night to reach him when word came to her and to his brother John, who was a physician, that he had again been struck with palsy and was dying.  That stroke of palsy followed immediately upon the finishing of the book now in the reader’s hand.  Davy lived to see again his wife and brother, rallied enough to leave Rome with them, and had got as far as Geneva on the 28th of May, 1829.  He died in the next night.
