376 Meteoric Iron of Texas and Lockport. 
phosphorus is very little more than is required to form a phosphu- 
ret with the nickel (Ni,P), or with about. half of the iron, 
and it is certainly difficult to conceive of the iron as retaining 
its magnetic condition, and resisting the action of hydrochloric 
, unless we suppose it to be in the state of magnetic oxyd.
