*The value of polonium is purely speculative. Minute quantities have been sold at very high prices. It is worth 75 cents a gram on bismuth and platinum plates. The quantity of polonium is of course very minute.

† The supply is so small that any price can be asked. $3,500,000 is the current " newspaper estimate per pound. See Radium, page 449.
