Abstract
THE black iron sand from New Zealand examined by Dr. Scott in 1915 in which, as he informed the Chemical Society at its meeting on February 1, he found a substance which he is now inclined to regard as probably identical with an oxide of the new element recently discovered by Dr. Coster and Prof. Hevesy of Copenhagen, and named by them hafnium, was doubtless similar in character to the deposit observed to occur in the bed of a rivulet at Tregonwell Mill, near Menaccan, in the parish of St. Keverne, Cornwall, and also in a stream at Lenarth, in the same parish, and in which the Rev. William Gregor, the minister of that parish, who analysed the deposit in 1789, first detected the existence of the element now known as titanium.
