I'ho ninjor portion of tho book summnriscs the scientific litcrnturc of zirconium nnd its compounds. genernlly in a non-critical nncl non-conimittnl spirit. Whcrc so mucli is rngiic and indcfinito tlio nutlior is no doubt wisc to postpone nny nttciiipt n t scpnrnting tlic nlinit from tlic t:ircs.

No pretence is mndc of giving full clctnils of ~nctliocls of scpnrntion nncl nnnlysis, but full rcfcronccs to tho litcrnturo arc given in tlic biblio~mpliy.
