as if other portions were attached at one time, but had been rusted 
off by a process of oxydation that has made several fissures in 
the mass so as to allow portions to be detached by the hammer, 
although when the metal is sound the smallest fragment could not 
be thus detached, it being both hard and tough. Its dimensions 
are such that it will just lie in a box 13 inches long, 11 inches 
broad and 54 inches deep. The accompanying figure gives a 
correct idea of the appearance of this meteorite.

The exterior is covered with oxyd of iron, in some places 8° 
thin as hardly to conceal the iron, in other places a quarter of an 
inch deep. Its hardness is so great that it is almost impossible to 
detach portions by means of a saw. Its color is white, owing to 
the large amount of nickel present ; and a polished surface when 
acted on by hot nitric acid displays in a most beautifully regular 
manner the Widmannstattian figures. The specific gravity taken
