5. On an eae Sawer ie owes of Iron.—DrmxEt has repeated 
the experiment of a upon a ferrous solution with potassium 
nitrite and a sociiaaa reatitade; first noticed by Roussin, in order 
to — more carefully the product. To prepare the compound, 
s potassium nitrite is prado im 300 ¢. ¢. water, the 
solution is added, and the Leste tinea for a few minutes, 
A solution of 33 grams crystallized ferrous det in 200 c.c. water 
is then added gradually with shaking and the liquid boiled for ten 
minutes. It is then filtered and the filtrate deposits black —
