Bessemer metal past all remedy,—Lieut. Dutton vere “T have 
already ventured the opinion that phosphorus increases its affinity 
for iron with every increase of heat; at least relatively if not ab- 
solutely. The fact seems to be, absolute tely. If we accept it, we 
can instantly explain what seem, otherwise, to be many anoma- 
lies and contradictions. It will explain to us why, in the great 
heat of the blast-furnace, it leaves every other combination and 
enters the iron; why, in the much lower heat of the puddling fur- 
nace it seems to waver between staying with the iron, or formin 
a of them formidable Ist. That a minute quantity of phosphorus 
into the blast-furnace, as fuel, flux, or ore, are almost wholly con- 
centrated in the resulting pig-iron ; and 3 at no portion Is

definite and rather narrow limits. Ma the same law ge

It seems to have been more severe in Canada and in New England. 
many places the shock was sufficient to throw down chimnies, 
erack the walls of buildings, and do other damage. It was re 
markably severe for the region of country visited.
