HOVEY, THE KINGSTON, N. M., SIDERITE 337 



from 0.5 to 1.5 mm. broad, but the usual width is 0.75 mm., where they 

 are not doubled or trebled. Some were measured that were practically 

 continuous for a length of from 75 to 85 mm. Neumann lines are abun- 

 dant and distinct, though occasionally obscured by a minute network 

 of curved lines. Tsenite is practically absent and plessite is extremely 

 subordinate in development. Thin, short lines of schreibersite may be 

 seen here and there, some of which are associated with little nodules of 

 troilite and some with the bands of kamacite. About fifty small nodules 

 of troilite were noted, varying in size from 1 to 8 mm. in diameter. 

 Lawrencite exuded rather freely from the crevices in the slices during 

 the dampness of summer. 



The iron is octahedral in structure, and the breadth of the lamellae 

 throw it into the medium octahedrites (OM) of Brezina's classification. 



A circle whose radius is 70 miles would pass through or close to the 

 places of origin of the following New Mexico siderites : Kingston, Luis 

 Lopez (Magdalena), Oscuro Mts., El Capitan and Sacramento Mts. 

 The irons, however, seem to be independent falls.
