DESCRIPTION OF THE PLATES. 



Plate I. 



Fig 1. — Shows the roughly trapezoidal, and slab-shaped form. The drift- 

 effect developed over the whole principal surface shows clearly only on the 

 more strongly illumined parts. In front, below, is the slightly inclined 

 surface over which the drift-effect is continued uninterruptedly wherever the 

 crust is preserved, so that these two surfaces together form the front of the 

 meteorite. The bright edge on the left has been chipped and covered with a poorly 

 developed secondary crust. The other surface is inclined at almost right angles 

 to the principal surface, and one can see the sharp edges in which these meet. 



Fig. 2. — The figured side, almost at right angles to the principal surfaces, has a 

 finely wrinkled crust with no drift-effect. Below, on the right, is seen the place 

 where the wedge-shaped piece has broken off ; here, on the two bevelled edges on 

 the right and left, as well as on the two arms stretching over the surface, the stone 

 shows a secondary crust. 



Plate II. 



Fig. 1. — The back, uniformly covered with scar-like impressions and wrinkled 

 primary crust ; towards the edge traces of drift-effect are to be seen. On the 

 lower edge the secondary crust can be clearly distinguished from the primary 

 crust. 



Fig. 2. — Front, with shallow scar-like impressions and drift-effect radiating 

 from the crown uniformly in all directions ; on the right half the slight depression 

 of the surface is observable. The darker parts at the edge are covered with primary, 

 the lighter ones with secondary, crust. The drift-effect of the primary crust 

 on the slightly sloping side on the right is in reality much sharper than 

 the photograph shows. 



Plate III. 



Fig. 1. — Shows the structure, slightly enlarged. 



Fig. 2. — Enstatite chondrule with the confused radiated structure ; an example 

 of the chondi'ules most common in this stone. 



Fig. 3. — Vertical section through the crust. The three zones are indicated only 

 in the middle portion bounded by two cracks, and not clearly there. Still, one can 

 see that silicates are sparsely present, and are of smaller dimensions than in the 

 matrix. 



Fig. 4. — Two nickel-ii'on chondrules. Of these, one encloses a small enstatite 

 chondrule, the other isolated enstatites. The chondrule next to the latter is one of 

 the rare ones, which are made up of a few broad enstatite crystals. 



Fig. 5. — Chondrule, with diverging radiated structure, with indentations and 

 numerous inclusions of iron pyrites. The section was treated with copper sulphate 

 solution, and the surrounding nickel iron appears, in consequence, in larger 

 connected particles than is actually the case.
