G.S. Higson visited the diamond fields of Griqualand West around 1870. Near present Kimberley he pointed out to F.A. Hubner* the difference in age between the agate-bearing amygdaloidal greenstone and the younger, darker greenstone; also that the shales there were underlain by claystone-porphyry (now recognized as Dwyka tillite). Upon his return to Britain he gave a lecture on "Diamonds and gold at the Cape" before the Royal Society of Arts in 1870. It was published in the society's Journal (Vol. 18, pp. 757-760) that same year, but contains little of geological interest. This is unfortunate, as Hubner's account of their meeting suggests that he was a keen observer. Higson is not known to have produced any other scientific papers or books.
This Higson may possibly be George Septimus Higson (1824-1871), partner with Henry K. Crofs in the Orange Free State firm Crofs and Higson, which was declared insolvent in 1860.
