✦ Synopsis

The incompleteness of scpnnition is only to be rinticiputcd in view of the Rninll nun~ber of frnctiotmtions nnd to the fnct thnt the volatilisntion point curve is of the crrntic hyperbolic type. Neverthcless, the elenletits grouj)ed together in the second nnd third frnctions nre those of rrtoniic weights suniciently different, to be ensily sepnrnted by tlic clnssicirl frnctioniil crystirllisntioti procedures.

COSCLWSIOXS

However brief, the foregoing report of the investigritions curried out run? be, it will serve to slio\v thnt by control of ntmospliere, pressure nnd tc~ni~)rnrt~lre, it is possible to conduct n rapid initid scpmrtion of the rim cnrth cleinents on the bnsis of the rolntilisntion tempcrntures of their chlorides. Although only one espcrimeiit was rnrricd out on the scpnrotiuu of tlic conipotietits of a nnturd niisture, the results obtniiied are higlily encournging nnd it may be thnt with ciiiploynient of strict tcnipernture control over a large nuniber of friictions, 11 cotnplcte hepiratioti of the riire curth eletnetits previously tdiing inniiy months-mid in sonic cnscs yenrs-will be complete in n ninttcr. of dnys. Furtlter investigntio~~s on this procedure nrc progressing.
