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
not given in quantity for all classes by Bureau of Foreign and Domestic
Commerce; estimated as 1,000 ounces of platinum.
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.
