The addition of aluminium to molt-

been found to render the metal per-
fectly sound when cast. The action
seems to be entirely chemical, and is
about twenty times more powerful
than that of silicon. The amount used
is from four to eight ounces ton. and
when used manganese can be dispensed
with.
The amount of phosphorus consumed
per annum is about two thousand tons.
