Examination of a fractured surface shows a light ashy gray 

 color and the granulated texture imperfectly reproduced in fig. 

 13. Irregular chond rules, visible to the naked eye, are com- 

 mon, and here and there others become prominent by their 

 spherical form breaking half free from the matrix. In some 

 instances these hemispheres are quite perfect and of four or 

 five millimeters diameter, the largest one, illustrated in tig. 14, 

 reaching 11 millimeters. It has lost much of its definiteness 

 in photographing. 



Under a lens, the chondrules breaking with the matrix are 

 seen to be numerously distributed throughout the mass. A

large number of the chondrules are gray in color, others are 

 whitish. Not infrequently a broken chondrule shows radio- 

 foliate structure, sometimes with the radiant point at one edge. 



Microscopic Examination . 



This was made by Mr. W. Harold Tomlinson, whose report 

 follows : — 



The new meteorite is an aerolite containing a very little 

 native iron. There are three opaque minerals forming together 

 perhaps 4 per cent of the volume. Native iron and pyrrhotite
