History of the discovery and separation

Tennant gave the name iridium to the metal which Descotils and Vauquelin had observed, and the name osmium to the new one (20). In speaking of iridium, osmium, palladium, and rhodium, W. T. Braude stated in his lectures in 1817, Of these, the two former were discovered by the late Mr. Tennant and the two latter by Dr. Wollaston and bad we searched throughout chemistry for an illustrative instance of the delicacy of the modem art of analysis, it would be difficult to have found any one more notorious than the history of the discovery and separation of these bodies exhibits (46). During the entire course of the researches which led to ibe discovery of these four metals, Dr. Wollaston and Tennant had friendly intercourse with each other, and each kept in close touch with...

In 1817 the English chemist and mineralogist W. Brande justly noted in his lecture devoted to the discovery of platinum metals that if one tried to analyse the entire development of chemistry from the standpoint of contemporary analytical accuracy, the history of the discovery and separation of platinum metals would, prohahly, be the most striking one.
