20 Dugald Clerk, The Work and Discoveries of Joule 



Without discoverers and inventors we would stagnate and 

 deteriorate ; with them we may advance some way yet to the 

 production of a better and happier human society. 



I wish to thank your Society for the great honour you 

 have done me by permitting me to pay my tribute to so< great 

 a man as Joule, whose work has been so vitally important to 

 mankind both in pure science and in practice.
