Heath , Comments:Comments:THE term “rare elements” is conveniently applied to thosemembers of the Periodic Table* whose chemistry in lit fie known.Home of these* elements are so scarce that their study has ofnecessity been difficult; others are abundant in nature*, buttheir development has been retarded by lack of sufficient interest;still others have only recently been discovered, and sufficienttime has not yet elapsed for them to lose the interest inherentin newness. The “rare elements1* then should be understoodto include? those elements which are little known either becauseof scarcity, neglect, or ignorance. The chemistry of norm* ofthese elements is developing rapidly, since* we are junt beginningto appreciate something; of their interest and usefulness. Rapidadvancement, has followed such an awakening,, and the namesof Home Htich substances have become household word*. Inother cases interest has been less keen and advancement hasbeen slow.
