French Claim to Priority of Discovery of Hafnjum The result of Professor Bohr's X-ray examination of the substance Dr. Alexander Scott, of the British Museum Laboratory, isolated in 1913 from some titaniferous black sand from New Zealand, and which he believed was identical with the new element, "Hafnium," discovered in zironium ore at Copenhagen University, showed that it was not the missing element No. 73, but probably another of the five missing elements, the nature of which has yet to be decided. While Dr. Scott accepts the verdict of Professor Bahr, who is the leading author: on the subject, and is able at Copenhagen to apply the most decisive X-ray tests, two Yprench physicists, MIN. Urbain and Dauvillier, have put forward a claim to have discovered an element identical in every respect with hafnium as long ago as 1911. At that time Moseley had not enunciated his fundamental law of atomic numbers, and the French scientists gave the name "Celtium" to their discovery, which they found associated with certain rare-earth metals. They have now submitted it to X-ray analysis, with the result that they claim to be the first to discover No. 73, and dispute the claim of the Danish discoverers, Professor Hevesy and Dr. Coster, to priority in this matter,
