Prag, 1814:
Given:
a) 7.9 Ozt Manufactured Platinum sold Paris Retail for Fr. 273 (Fl. C.M. 105.)
b) 7.9 Ozt Manufactured Platinum sold London Retail for £ 7.11 (Fl. C.M. 64. - 67.50)
and assuming:
c) 'transport costs' unknown, from Paris (or Vienna?)
d) Voltaic Piles of similar dimensions sold elsewhere about London Retail (Fl. C.M. 90)
it follows the given price "Fl. 132" can only be for the Platinum, Manufactured and Imported at a local cash price, all costs included.
1814: 1 Troy Ounce Platinum (Paris Import: Mfg) = Fl.C.M. 16.71 (Fr. 43.44)
In this year the chemical laboratory has been enriched with the following devices:
With a voltaic column apparatus, consisting of 106 copper and as many zinc plates, 4 Zoll in diameter, together with the corresponding thereto to medical and chemical tests required devices from silver, which in fine silver 19 Loth 5 Quenschen less weighing 10 Gran {~355.1 g/ 11.42 Ozt. ; =Fl. 30.395}
With, together with a platinum crucible with helm and cover, totaling 7 Unzen, 120 Gran Viennese apothecary weight {= 7.90 Ozt}, which, together with the costs incurred for transport comes to to Fl. C.M. 132. { ~Fr. 345. {in currency, highly variable rate}
In England, the Volta Pile of the same dimensions cost exactly £ 10. (Fl 90. - 95.)

National Coin-money assayeur Freiherrn Franz Xaver von Leithner
The chemist can Mr. Leithner consider the more connected than many now, namely by massive price, a crucible etc of platinum will be able to provide, where the opportunity is not so oflen, like himself, to much dearer prices to have come from Janety in Paris.
