The Rev. Joseph Campbell, M.A., F.G.S., F.C.S., Vicar of Papanui, was born in Sydney, New South Wales, in 1857, and was educated at Sydney University, where he took his B.A. degree in 1880; became Belmore Gold Medallist for Geology and Agricultural Chemistry, and M.A. in 1882, School of Natural Science; F.G.S. and F.C.S., England, 1886; Curate at St. Michael's, Surrey Hills, Sydney, 1830 till 1883; Acting-Professor of Eperimental Physics at the University, Sydney, 1882–1883; Vicar of Holy Trinity, Glen Innes, diocese of Grafton and Armidale, 1883–1890; S.P.G. Deputy page 195 and Locum Tenens, Long Wittenham (Oxon.) and Laleham (London); Locum Tenens at St. Jude's Randwick, Sydney, 1890–1891; Vicar of St. Nicholas, Cogee, 1891–1897; Principal of St. Nicholas College, Randwick, 1893–1897; Fellow of St. Paul's College, 18931897; University Extension Lecturer on Geology and Chemistry, 1893–1897; ad eundem Master of Arts, New Zealand University, 1902. During the Continuance of his principalship at St. Nicholas College, Randwick, from 1893 till 1897, Mr. Campbell directed his attention to the laboratory, with a view to dealing with refractory gold and silverbearing ores, and discovered that the best method in all cases not amenable to the cyanide process was by treatment with water gas, of which method he became the patentee and named it the thermohyperphoric, which means elimination by heat. In 1896 Mr. Campbell went to England and laid the matter before metallurgical authorities, who confirmed his conclusion. A company was thereupon formed in England, and Mr. Campbell came to New Zealand and erected large works at Te Aroha. During his stay in England he was elected a member of the Institute of Mechanical Mining Engineers, and contributed a paper on “The Goldfields of the Hauraki Peninsula,” for which the council awarded him its prize. After his return to the colony, he devoted three years of constant application to the study of the refractory ores of New Zealand, and although he claims to extract ninety-five per cent, of the gold, the conclusion was forced upon him that, as the major part of the ores at Te Aroba assay less than 20s per ton, they cannot be profitably handled. During the elaborate series of experiments conducted at Te Aroba, Mr. Campbell discovered a simple, cheap, and effective method of smelting concentrates. This still remains a secret, but will be made known when the handling of payable concentrates renders it necessary. One of Mr. Campbell's objects in entering the ministry of the Anglican Church was to show the harmony existing between science and religion, and when filling scientific positions, he served the Church almost gratuitously. During his stay in the Auckland province he acted as honorary locum tenens for about fifteen months at St. Sepulchre's, during the absence of the Ven. Archdeacon Dudley, on sick leave, and his popular methods of preaching drew large congregations. After being in temporary charge of the parish of Tinwald for three months, and for a similar period at St. Paul's Papanui, Mr. Campbell was appointed vicar of St. Paul's on the 14th of March, 1901. Mr. Campbell's best known publications are: “Simple Tests for Minerals, or Every Man his own Analyst,” fourth edition 1897; sermons on “Difficulties of Belief,” preached at St. Nicholas, Cogee, 1897; and “Notes on Confirmation,” 1901. Mr. Campbell was married, in 1881, to a daughter of the late Mr R. Holt, of Sydney. Mrs Campbell died in London on the 24th of October, 1901.
