John Daniell, Fellow of the (British) Chemical Society, was a member of the Chemical and Metallurgical Society of South Africa in November 1897, when he read a paper on "School of Mines for the Witwatersrand" before its members in Johannesburg. The paper was published in the society's Proceedings (Vol. 2, pp. 156-163). [The South African School of mines, established by the South African College (Cape Town), provided part of its tuition in Kimberley and Johannesburg from 1896. It was the earliest forerunner of the University of the Witwatersrand]. In March 1898 Daniell delivered his second paper to the society, on "The scorification assay" (Proceedings, Vol. 2, pp. 276-279, discussion pp. 322-327). He was still listed as a member of the society in 1899, but not after the Anglo-Boer War (1899-1902). In 1898 and again in April 1899 he applied for an appointment as lecturer in chemistry and metallurgy at the Government Mining School of the South African Republic (Transvaal).
