The technical working of massive platinum should be ascribed, however, to Thomas Cock, a brother-in-law of the platinum-refiner P. N. Johnson, rather than to Wollaston. Cock worked out the process in William Allen s laboratory at Plough Court and, at Allen s request, communicated it to Wollaston (51). According to G. Matthey, P. N. Johnson was the first to manufacture platinum on a commercial scale and the first to prepare a large and perfect sheet of the pure metal. James Lewis Howe has stated that Chabaneau s process was rediscovered by Knight and possibly also by Cock (72). 

The Journals examined arc approximately the same as those listed in James Lewis Howe s unexcelled Bibliography of the Platinum Metals and the plan followed is in general the same as outlined by him. The abbreviations used are familiar to all chemists.
