ART. Kae On te Determination of Phosphorus in Tron ; 
y J. LAWRENCE Switu, Louisville, Ky. 
IN recent years it has been a matter of considerable interest to 
determine the amount of phosphorus in the iron used in the arts, 
especially in that form of it known as pig iron; in fact, since 
the manufacture of — by the process of conversion known 
as the Bessemer process, it has become a necessary procedure 
to ascertain the peculiar Hise of the cast-iron for this purpose ; 
and has a bearing also upon the commercial value of pig-iron. 
It is not many years ago that a few thousandths in the differ- 
ence in the amount of phosphorus in two lots of pig-iron had 
but little effect upon its commercial value, while now, its pres- 
ence affects it to the extent of several dollars value per ton. 
Formerly but little reliance was to be placed upon the 
analy scat estimate of the amount of these small percentages of 
s in iron, and uniform results were not furnished by 
different analysts. It was not until the use of an acid solution 
were to be had. Many years previous (in '1852), when I estab- 
was obliged to devise a process which, rue it gave very good 
results, was not applicable to the present 
The so-called molybdiec acid process did t not at first satisfy 
* Method of making described in Fresenius’s Analytical Chemistry.
