LECTURE ON PLATINUM.
[_Delivered before the_ ROYAL INSTITUTION, _on Friday, February 22,
1861._]
Whether I was to have the honour of appearing before you this evening or
not, seemed to be doubtful upon one or two points. One of these I will
mention immediately; the other may or may not appear during the course of
the hour that follows. The first point is this. When I was tempted to
promise this subject for your attention this evening, it was founded upon
a promise, and a full intent of performing that promise, on the part of my
friend Deville, of Paris, to come here to shew before you a phenomenon in
metallurgic chemistry not common. In that I have been disappointed. His
intention was to have fused here some thirty or forty pounds of platinum,
and so to have made manifest, through my mouth and my statement, the
principles of a new process in metallurgy, in relation to this beautiful,
magnificent, and valuable metal; but circumstances over which neither he
nor I, nor others concerned, have sufficient control, have prevented the
fulfilment of that intention; and the period at which I learned the fact
was so recent, that I could hardly leave my place here to be filled by
another, or permit you, who in your kindness have come to hear what might
be said, to remain unreceived in the best manner possible to me under the
circumstances.
