Power of Heat," " On the Dynamical Theory of Heat," 

 and numerous others are to be found in the Transactions 



of the Royal Societies of London and Edinburgh. His 

 papers began to appear in book form in 1882. 



In 1851 he was elected F.R.S. (along with Huxley 

 and Stokes), and, after having received the Royal and 

 Copley medals, he was in 1890 chosen President of the 

 Royal Society. He was one of the eight foreign 

 associates of the Academic des Sciences; D.C.L. of 

 Oxford, and LL.D. of Cambridge, Edinburgh, and Dublin 

 Universities ; and he possessed most of the honours 

 awarded to men of science. 



Lord Kelvin was twice married. His first wife, the 

 daughter of Mr Crum, F.R.S., died in 1870, and his 

 second wife was the daughter of the late Mr Blandy 

 of Madeira. For many years Lady Kelvin was his 

 companion and helper ; and they sailed in their 

 yacht the Lalla Rookh over many seas, for Lord 

 Kelvin was a navigator as well as a physicist and 

 mathematician. 



In 1892 he was made a peer of the realm by Queen 

 Victoria. He was a Knight of the Prussian Order Pour 

 le Merite, a Grand Officer of the Legion d'Honneur de 

 France, a Commander of the Order of Leopold of Belgium, 

 a Grand Cross of the Victorian Order, a Member of the 

 Order of Merit, etc. As Lord Kelvin left no heir the 

 barony became extinct.
