He was appointed reader in Chemistry and Mineralogy at Durham University on its foundation in 1833, but continued to reside in Edinburgh out of term. He wrote the Catechism of Agricultural Chemistry (1844), since translated into most European languages, and the Chemistry of Common Life (1853–1855). From 1847, his assistant was Augustus Voelcker who also lectured in agricultural chemistry at Durham University.
Johnston died in Durham on 18 September 1855.
Johnston formed a grammar school in Durham in 1825, which later merged with other local schools, such as Brandon and Bowburn, to form a single comprehensive school for the area, named Durham Johnston Comprehensive School, preserving James Finlay Weir Johnston"s name.
