When Hirst returned to Scotland in 1947, he knew that the Edinburgh laboratories already contained a very active research school in carbohydrate chemistry that had been built up by E. G. V. Percival, whose work was mainly concerned with the structure of plant mucilages and seaweed polysaccharides. These interests were complementary to Hirst s own recent studies in Manchester on the structure of polysaccharides, particularly the plant gums, and the next few years saw a renewal of the successful collaboration of the Birmingham period 1930-1933, until the untimely death of Percival in 1951. 

Finally, Hirst s later contributions to monosaccharide chemistry must not be overlooked. With E. G. V. and Elizabeth Percival, four different trimethyl, 3,4- and 4,5-dimethyl, and the 4-methyl ethers of D-fructose were synthesized from isopropylidene derivatives having well established structures. Certain methyl ethers of D-mannuronic acid and D-glucuronic acid were also prepared, and their periodate oxidation was compared with that of related ethers of D-galacturonic acid. With Elizabeth Percival, he also contributed articles on the methyl ethers of mono- and di-saccharides, and on glycofuranosides from cyclic carbonates, to Methods in Carbohydrate Chemistry, Vol. 2 (1963).
