Nilson's papers: pp. 642-645 a. 645-648. First leaf with a tear to right margin, no loss of paper.

It was the second new element found after Mendeleev's prediction of its existence as "Eka-Boron"."Mendeléeff had predicted that another element, which he called eka-boron and which he said would have an atomic weight between 40 (calcium) and 48 (titanium), would some day be revealed. It was discovered in 1879 by Lars Fredrik Nilson. Nilson extracted 63 grams of the rare earth erbia from gadolinite and euxenite, and converted it into the nitrate. Upon decomposing this salt by heat, as Marignac had done, he obtained some very pure ytterbia and, to his great surprise, an earth that was unknown to him.Upon thoroughly investigating this new earth, he found that it contained an element whose properties concided almost exactly with those Mendeléef had predicted for ekaboron.
