Brezina M groups Guilford County with Toluca, and describes it as having small, slightly 

 puffy lamellae, 0.5 mm. wide. 



The small quantity of the iron known is distributed.

Iron. Hammond group of octahedrites (Oh), of Brezina. 



Found 1884; described 1887. 



Weight, 24 kgs. (53 Ibs.). 



The first account of this meteorite was by Fisher, 1 with a note by Kunz, and was as follows: 



The mass of meteoric iron described in this paper was ploughed up three years ago (1884) in a cornfield on the 

 farm of Mrs. Jenette Rattary, in Hammond Township, St. Croix County, Wisconsin. (The exact description of the 

 40 acres is: N. SW. J Sec. 31, T. 29 ., R. 17 W.) 



It attracted attention from its weight and silvery luster where freshly abraded, and was supposed to contain silver, 

 but its real nature was not suspected, and it lay about the farmyard until last winter. At that time, during the excite- 

 ment about iron ores in that neighborhood, a speculator chanced to see it and he at once paid $50 for an option on the 

 40 acres to prospect for iron ore. The mass was sent to me for analysis, and on its being reported to be a meteorite 

 was reclaimed by the owner, and it was not until I visited the region in May last that the facts of its discovery were 

 ascertained. 



It was struck by the plow near the surface of the ground in a field that had been cultivated for corn for several 

 successive years, and the fanner was quite certain that it could not have been there the year before, and its fresh 

 appearance noted later, testifies to the probability of its having recently fallen. It is quite remarkable that it kept 

 so bright during the three years it lay in the fanner's yard. No similar pieces have been seen, nor does this show signs 

 of fracture. 



The mass has been considerably disfigured by attempts to chisel off pieces at different points, and one piece was 

 detached and forged into a spike, but this I did not see. When it reached me, it weighed 53 pounds (24 kg.). It is 

 of irregular shape, as shown in an accompanying cut, engraved from a photograph I had taken when it first reached me.
