Suisse, 1838

Presumably calculating in the Swiss fluid ounce (not an English ounce, nor the long since abandoned Paris once)  Dr. Melly in Geneva assumed '1 once = 27cc' so "15 once de l'eau" is 405 cc (or 13.69 US fluid ounces, 14.25 British Imperial ounces.) 

By volume, a 400 cc dish weighed about 105 g; a platinum vase of 3.3735 Ozt. for "at least" Sw.Fr. 200 implies a very high cost (import duty?) exaggerated:

c.1836: 1 Troy Oz. Platinum (Mfg, Ret) = Sw.Fr Sw 59.29 (USD$ 11.16)

At nearly 1/10th the price, the plated manufacture (w/ 14 g platinum) would cost just SwFr 30, all labor and materials.
