Robert Were Fox the Younger died on 25 July 1877 and was buried at the Quaker Burial Ground at Budock.

[4] Fox's gardens at Rosehill[5] and Penjerrick, near Falmouth, became noted for the number of exotic plants which he and his son, Barclay, had naturalised.

[8] In 1829 he began a set of experiments on the artificial production of miniature metalliferous veins by means of the long-continued influence of electric currents, and his main results were published in 1836.

[c] One was used by Sir James Clark Ross on his Antarctic expedition and used to discover the position of the South magnetic pole.

[11] He was a key person in the development of the Royal Cornwall Polytechnic Society and its promotion of scientific research and training.
