October 1887: Prototypes - Additional Expense, Fr 16,341
Prototypes (meters and kilograms) are drawn Iridio-Platinum. The metal is provided by the firm Johnson, Matthey and Co. of London, which alone, it seems, can provide the necessary amount of Platinum. The instruments are completed by the French Section, which delivers them to the international office, located at the Pavilion de Breteuil. After the necessary tests, the office receives them permanently, from any location. To date, foreign states have requested 40 kilogram weights and 30 rulers. The 40 kgs are nearly complete. The 30 rulers were delivered to the French section, which continues completion. It is estimated that required prototypes shall be distributed in 1888; so it is at this time that the price will be refunded to the French Government, which governs all expenses. The appropriation is justified and your commission proposes adoption.
Scrap was accepted at Fr 900./Kg. The Kilogramme Standard cost Frcs. 2,150. each; the Metre Standard weighed 3.50 Kgs and cost Fr. 9,500./ea. but sold for Frcs. 9,600.
1873: 1 Troy Oz. Platinum (Scrap, Credit) = Fr. 27.99
1873-87: 1 Ozt. Platinum (Cost: Mfg, Bulk) = Fr. 66.87
1873-87: 1 Ozt. Platinum (Cost: Mfg, Bulk) = Fr. 84.42
1873-87: 1 Ozt. Platinum (Price: Mfg, Bulk) = Fr. 85.31
1887: 1 Ozt. Platinum (Total Cost, Bulk Mfg) = Fr. 81.73
This work, begun in 1873, did not cease to be continued since but was found delayed by various incidents independent of the willingness of members of the French Section. Types prepared after laborious operations were not judged acceptable to the Internalional Commission, the work had to be entirely redone; however, it is nearing its end, and the firm of Mathey and Co., with which the Ministry has dealt for making rules and directions to be making masses of meters and kilograms, standards, will shortly have delivered the work in its entirety; additional operations are performed and we can foresee the very next time standards will be presented at the International Bureau of Weights and Measures installed Pavilion Breteuil and responsible for making the final comparisons before final acceptance.
Expenses must be reimbursed by the States to which standards are remitted; but it is the Government of the Republic shall make advance. Already, extraordinary appropriations were for this purpose, at various times, the Ministry of Trade; it is necessary that his administration soon be able to pay the new accounts that will be provided by different suppliers, and it is essential to ask for a date, for this purpose, the budget for the 1887 financial year the opening an extraordinary credit 1. Messrs. Mathey and Co have a supply 30 meters in Iridio-Platinum, each weighing on average 3.500 kgs; metal prices have been fixed by them at past market price, at Fr. 2,000/kg., the expenditure on this account amounted to Frcs. 210,000.
In addition, it is due to them for the manufacture, rightly, Frcs. 2,500 each ruler = Frcs. 75,000
They also delivered 40 kilograms worth at Frcs. 2,000, each = Frcs. 80,000
The manufacture is set at Frcs. 150 per kilogram, or = Frcs. 6,000
Finally, it is appropriate to take account of their waste, which can be evaluated = Frcs. 4,000.
To ensure uniform composition of the alloy, samples were provided on various occasions, analyzed in Paris, by Mr. Debray of the Institute, and in Brussels by Mr. Stas; it must be allocated for the metal and used a fixed sum of = Frcs. 6,000
