FLORENTIUM, the name given to element No. 61 by L. Rolla and L. Fernandes, who claim to have deposited a paper announcing its discovery with the Accademia dei Lincei in June 1924. On the other hand, B. S. Hopkins disputes this claim (see J. Franklin Inst., 1927, 204, p. 1) and has named the element "illinium," under which title it is described. (See also RARE EARTHS.)
