Messrs. Levi and Kunzel, of the Val Benvit Nickel-Works, near Liege, Belgium, have, for a number of years past, been engaged in making experiments for the purpose of improving bronzes of this kind The results of their experiments are thus summed up by M. Dumas: —
The color, when the proportion of phosphorus exceeds one half per cent, becomes warmer and like that of gold largely mixed with copper.
The grain and fracture approximate to those of steel.
The elasticity is considerably increased, the absolute resistance under a fixed strain becomes more than do
