Iron, Og. Two slices, weigliing 98 and 102 grams, respectively. 

 Etched showing Widmanstiitten figures. Found in 1810; date of fall 

 unknown. Original weight perhaps 30 zentners (3,000 pounds?), of 

 which the greater part was smelted, only some two zentners (200 

 pounds?) being saved. Composition: Analysis by Patera (I) and 

 Lowe (II) yielded: 



It was the nickel-iron phosphide found in this iron to which 

 Haidinger and Patera first gave the name schreibersite.
