Spongy Metals in Therapeutics.— Telegraphic Messages. 103 
for wood charcoal in preparing moulds of clay for receiving copper, 
bronze and melted cast iron, proposed by a poor armorer, M. Rouy ; a 
plan now generally adopted in the founderies in France, because it is

Spongy Metals used in therapeutics.—We have already spoken of 
the spongy metals which M. Chenot has obtained by reducing the ni 
ized ores by means of a gaseous mixture of hydrogen and of oxyd of 
carbon produced through the decomposition of steam by incandescent 
charcoal. M. Chenot now proposes the use of these Sponges OE He
