a The figures used aboveincludeimports of manufactured platinum, iridium, and palladium, and a figure which is the diflerence between the item in the first column of the table on page 12 and the quantity of crude platinum that refiners report they used during 1919. This difference has been interpreted as repre­senting imports of refined platinum. There is also added 122 ounces of manufactured ware which has been included under platinum, though this material may have contained some iridium.
t> Exports not given in quantity for all classes by Bureau of Foreign and Domestic Commerce; esti­mated as 1,000 ounces of platinum.
It will be noted that the total quantity of platinum metals con­sumed as calculated above—156,422 ounces—is very close to 154,743 ounces, the figure arrived at by the first method of computation. It is therefore entirely reasonable to assume that the consumption of platinum metals in the United States in 1919 was approximately 155,000 ounces.
STOCKS OF PLATINUM METALS.
Refiners and dealers in platinum metals reported stocks of 43,432 ounces on December 31, 1919, as compared with 64,814 ounces on December 31, 1918.
Stocks of platinum metals on hand Dec. SI, 1918 and 1919, in troy ounces.
There is some question as to the accuracy of the figures in these tables; it is certain, however, that they reflect the trend of affairs. It must be admitted that we are drawing heavily on supplies that are not adequate and that probably will not be adequate for some years, at least. The stocks of iridium and of palladium are nearly the same for 1918 and 1919, but the stocks of platinum have been lowered about 43 per cent.
