M. McCann sent his paper to JH for communication to the R.S.L., which he did, but does not know the outcome of it. Was unable to report on it as his own knowledge was not modern enough.

Asks for latest chemical information on platina groups, or 'Platinoids.' In trying to remove platina from mineral specimens JH may have found new metal. Describes its characteristics. P.S.: Keep this information private.
Thanks for information [on latest platina research]. Has encountered 'a totally new metallic chemistry.' Searching for papers by Mr. Gros and Mr. Beiset. Describes JH's experiments with 'Platinoids,' which JH named like asteroids: Heberum, Astraeum, and Neptunium.
Encloses JH's letter of 11 Oct., which was not mailed to RK. Discovered traces of titanium in Astraeum. Puzzled by saline compounds that appear in JH's experiments with 'Platinoids.'
