As examples of his work I may mention his papers on “The 
Vapour Pressure of Aqueous Solutions,” “The Affinity Constants 
of Weak Bases and of Organic Acids,” “The Hydrolysis of Salts,” 
and “The Boiling Points of Homologous Compounds.” 
I cannot allow this opportunity to pass without testifying 
to Professor Walker’s great ability as an investigator in pure 
Chemistry. Besides the investigations which he and I carried on 
together, and of which the results were published in the Society’s 
Transactions, he has, since he left Edinburgh, published valuable 
papers on Camphoric Acid and its Derivatives, which throw much 
light on their constitution.
