Martin Stanger Higgs was a member of the Chemical and Metallurgical Society of South Africa (founded in Johannesburg in 1894) for a few years until about 1898. In November 1895 he read a paper before its members on "Antiseptics and disinfectants", which was published in the Proceedings (1894-1897, Vol. 1, pp. 194-201). In 1903 he was still (or again) living on the Witwatersrand, for he participated in the discussions of two papers read before the Geological Society of South Africa that year, one by G.A.F. Molengraaff* on the Vredefort mountain land, the other by J. Kuntz* on the Main Reef near Klerksdorp. He was, however, not a member of the society at this time.
His only other known publication was a note on a species of butterfly, "Size variation in Lycaena alexis", which was published in The Entomologist's Record and Journal of Variation (1890, Vol. 1, p. 35).
Higgs was married to Catherine Hannah Adams. They had a son named Stanger Higgs who was killed at the battle of the Somme in France towards the end of World War I in 1918. Higgs is probably the same person as "M.S. Stanger-Higgs" who obtained a permit to import a double-barrelled shotgun in 1904.
