In Memoriam.

William Skey, the late New Zealand Government Analyst, was born in London on the 8th April, 1835, and showed an early taste for chemistry, especially in its bearing on agricultural pursuits. On his leaving school he was put to learn practical farming, and, with his employer's son, built a laboratory in his spare time, for the purpose chiefly of trying the business of distilling spirits of wine from beet-root. A large quantity of the roots was contracted for, but, unfortunately, they were grown on peaty soil, and consequently only contained a small percentage of sugar, so that very little spirit was produced. This and other circumstances led to the abandonment of the enterprise, and in 1860 Skey, along with his brother Henry (now in the Survey office at Dunedin), emigrated to New Zealand, where they spent some time on the Otago goldfields, which were discovered at that time.

Early in 1863 he was appointed Laboratory Assistant to the Geological Survey of Orago under Dr Hector, in place of Mr. Charles Searles Wood, Associate of the Royal School of Mines, who received an appointment on the Geological Survey of Victoria. Mr. Skey continued Analyst to the Geological Survey Department of the colony for twenty-seven years, until 1894, when he was nominally transferred to the Mines Department, continuing, however, to work in the same old laboratory until within six weeks of his death, which occurred on the 4th October, 1900.

For thirty-eight years Mr. Skey served the Government, and with indefatigable industry applied his great talent for chemical research. The Laboratory register when he left off work showed entries which cover 12,416 separate analyses, more than ten thousand of which were performed by Skey. Outside his laborious official duties he made many original contributions to chemical science, such as improvements in laboratory appliances; the electrical properties of metallic sulphides; the discovery of the ferro-nickel alloy “awaruite” in the ultra-basic rocks of West Otago, which is highly interesting as being the first recognition of a meteoric-like iron as native to our planet; the discovery that hydrocarbon in oil-shales is chemically and not merely mechanically combined; the discovery of a remarkable colour-test for the presence of magnesia; and the isolation of the poisons of many native shrubs. His suggestions for purifying water-tanks in India, for the use of the hot-air blow-pipe in the laboratory, and for the application of cyanogen salts to gold-saving, were some of his early achievements, which are now in practical use all over the world. His discovery that fatty oils treated with anilines form alkaloids hints at an important new departure in organic chemistry.

These and many other practical applications of Skey's chemical talent are distinguished services to science, of which New Zealand should be proud. Without much training Skey, possessing a natural bent, developed by diligent labour and hard study, attained to such a position as to be recognised as one of the world's famous authorities in certain branches of chemical science.

In William Skey the colony has lost a good servant and an able scientific man. He used to say that chemistry, farming, and poetry were the three things he took most interest in, and would sit up all night in the Laboratory composing and printing his poetical fragments with a hand type-press.
